12 best grinders

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

In everyday life and professional activity, we constantly use various tools that need sharpening. From the knife to the cutter, everyone enjoys working if the edges are straight and sharp. Therefore, our experts have prepared a rating of the best grinding machines for straightening the cutting part of both conventional and specific tools. The material is compiled on the basis of numerous reviews and after careful comparison of product characteristics, which will help you choose proven equipment for different needs.

How to choose a grinder

Before starting to study the rating, it is worth considering how to choose a grinding machine in order to understand what these or those characteristics in the description say. Here are the main criteria to look out for:

1. Power. For household machines, 150-250 watts are enough. This is enough to sharpen a knife and garden tool. For professional use, machines are made with a power of up to 600 W. The ability of the engine to withstand the loads from the clamping of the sharpened parts and not overheat at the same time depends on this indicator.
2. Number of revolutions. Thin steel is sharpened at low speeds, otherwise it will overheat and release. Thick objects are sharpened at high speeds from 2000 rpm. In the case of carbide elements, a high speed of rotation of up to 15,000 rpm is required.
3. Landing diameter. Varies from 12 to 32 mm. The larger the shaft, the larger the circles are allowed. Mounting a large circle on a small shaft is not permitted.
4. Circle diameter and width. These values ​​affect the size of the tool to be sharpened. Small parts (knives, chisels, chisels) are sharpened on small and thin circles. Large objects (axes, scythes, hoes) need wide and large abrasive products. This will provide better edge flatness and performance.
5. Protection and convenience features. Grinding machines are equipped with various attachments for better performance and safety. For example, it can be a support for a stop, and for some models also with a variable angle. Protective transparent screen, covering the operator's eyes from the escape of small particles. Directional illumination to better see the sharpening quality. A bath for cooling and rinsing the equipment.

Understanding the main selection criteria, let us turn to the consideration of the best grinding models from the rating, divided into categories by the purpose of the equipment.

The best universal grinders

The universal machines are designed so that both small objects and large parts can be sharpened comfortably in them. These are the best devices for everyday life, installation in a garage or in a small enterprise where wood or metal is processed.

ELITECH ST 600C

Rating: 4.9

A well-assembled machine with a metal body. Inside there is a 600 W motor that can easily cope with tight pressing of parts and will not slip at the same time. A common shaft passes through the engine, along the edges of which two circles are installed: on the left with small granules, and on the right with large ones. Both emery have a diameter of 200 mm and a width of 2.5 cm. The abrasive elements are enclosed in a robust casing, and the eyes of the craftsman are protected by plexiglass screens with adjustable position. The manufacturer did not forget about the backlight lamp on a flexible leg, which is easy to direct to any point. The start button is rubberized and will not harm when pressed with wet hands.

In our opinion, the universal machine should be in the rating due to the extra strong stops with reinforcement on the bottom side. These are not simple plates, but thick strips that can withstand heavy loads. Their height is adjustable, and there is even a recess on the left for a secure location of the drills. According to the reviews, it can be seen that the powerful grinding unit does not vibrate on the table, so the use is quite comfortable.

Advantages

• one of the glasses is magnifying;
• good equipment;
• heavy (12 kg) and well balanced;
• circles homogeneous by the size of the abrasive.

disadvantages

• uninformative assembly instructions;
• the tray for cooling parts is very small;
• small stones cannot be placed;
• the engine heats up with prolonged use.

ZUBR ZTShM-200-450

Rating: 4.8

A modern universal grinding machine with a compact body and two circles with a diameter of 200 mm. The rotation provides the motor with a power of 450 watts and accelerates to 2950 rpm. The machine is equipped with an LED lamp on a flexible leg, folding glass screens and thin stands with a variable distance to the emery. There are two holes in the bottom of the case for permanent fixing. The model is delivered in a package with a seal 'Bison', confirming originality.

In the feedback from the owners, it can be seen that the machine is more stable and does not run loose on the table. For this, it has wide support legs that prevent the equipment from moving from vibration. This model from the rating is the best for places of work, where you often have to rearrange equipment to clear the place or put it away for storage. For subsequent use, the model does not have to be fixed to the table.

• optimal power 450 W;
• acceptable price;

VORTEX TS-400

Rating: 4.7

A simple domestic model with an air-cooled motor. The grinding unit consumes 400 W and develops a speed of 2950 rpm. The device works with large circles 200 mm in diameter and 2.0 cm in width, but it is endowed with a specific seating shaft with a size of 16 mm, so buyers say that it will be more difficult to find equipment for it. The budget has affected everything – except for the backlight, the device has nothing. Absent: stops, bath, protective screens. On the other hand, the luminaire bracket is long and flexible, which allows you to bring it to any side and clearly see the workflow.

Our experts recommend this model from the rating as the best for the garage. On a coarse emery, it will turn out to quickly fix an ax, a cleaver and a chisel, and on a fine one to sharpen knives, drills and garden tools. The cost of the machine is two times lower than similar products from other manufacturers, which will not create problems for the family budget.

Advantages

• almost not heated;
• slight vibration;
• affordable price;
• no loud hum.

disadvantages

• specific bore diameter 16 mm;
• inconvenient lamp;
• for coarse emery 200 mm, the engine is a little weak;
• fixing on the table is required, otherwise it will 'run'.

Wert GM 0315

Rating: 4.7

Grinding machine with two small stones 150 mm in diameter and 16 mm in width. They put on a shaft with a fit of 1.27 cm. A 250 W motor starts rotation, but the speed is at the level of professional equipment and is 2950 rpm. The start button is protected from water ingress and there are two stops with a variable distance. Protective screens with an expanding shape to better block the path of escaping particles. In the reviews, the owners note the absence of beating of stones.

The sharpener is ranked as the cheapest in the category. But the affordable price affects the size, so the equipment is not suitable for sharpening large tools and equipment. Since buying it only for straightening knives in the kitchen is not profitable, our experts recommend paying attention to argon welders who constantly need to sharpen tungsten needles of non-consumable electrodes. A fine abrasive disc will provide a perfect taper to promote neat seams. On a rough stone, it will turn out to process the seam itself on a pipe or small plate.

Advantages

• consumes electricity like two light bulbs;
• high rotation speed of 2950 rpm;
• lowest cost;
• weight 5 kg – can be placed even on a simple stool.

disadvantages

• plastic case;
• needs to be fixed on the base;
• poor equipment;
• only for small circles.

The best machines for sharpening drills and knives

Sharpening knives and drills with a regular sharpener requires skill and skill. The blade of kitchen utensils can be simply grinded or burned, and the drills will remain dull due to the wrong angle. Therefore, manufacturers produce machines with already prepared slots, where you just need to insert the equipment, and the device will do the rest itself. Here is a ranking of the best sharpening models of this type.

Diold MZS-0.2

Rating: 4.9

Electric machine powered by a single-phase 220 V network, consuming 200 W per hour of operation. Despite its compact size and low power, it develops a rotation speed of up to 5500 rpm, which allows you to effectively sharpen carbide steel on drills. A handy chuck is provided to secure the tooling, as well as a centering system to ensure even passage of the edges. A nest with a horizontal entry opens up access to the sharpening stone, and by placing a cartridge in a vertical hatch, it will be possible to remove burrs.

Proven grinder, sold for several years and tried and tested by users. According to the reviews, it is clear that the machine is reliable and productive, but you can not buy circles on it everywhere. Therefore, it is not suitable for large volumes of work. But our experts recommend drawing the attention of those who need sharpening of 13 mm drills. Not every model is able to accommodate such equipment, but this one is designed to work with such dimensions, for which it received a place in the rating.

Advantages

• light weight 1.9 kg allows you to carry the equipment with you when changing workplace;

The manufacturer has interestingly implemented a system for fastening the equipment. The model has three blocks for holding drills, scissor knives and chisels. One stone works at the heart of the structure, and the blocks are attached to this part of the body alternately. In order not to lose unused parts, fastening is provided on the sidewalls. The module designed for chisels and thick ax blades has a degree switch that provides sharpening at different angles. Users refer to it as a quiet device without vibration.

The experts ranked the machine as one of the best thanks to the secure system for holding large tools. When sharpening chisels or chisels, the equipment is fixed with a magnet, which prevents the object from being pulled out of the hands.

Advantages

• small dimensions and weight;
• can be fixed to any surface;
• aluminum body around rotating stones;
• convenient start button on top.

Patriot BG 100

Rating: 4.7

American brand assembled in China. Equipped with a power of 96 W and accelerates the circle with a diameter of 56 mm to 1350 rpm. The grain size of the stone is 180 units, which ensures accurate grinding of the edge and sharpness. The rubberized cable is resistant to negative temperatures and remains flexible for a long time. The machine was made of plastic, which made it possible to reduce the cost and weight. By analogy with other brands, it has three repositionable blocks for securing different items. The module for chisels and chisels has a screw for adjusting the tilt position, but without indicating the degrees, so you will have to adjust the device by eye. In the reviews, the owners note that this is an exclusively household model, because the circle will quickly be erased from frequent use.

Experts recommend a multifunctional sharpener from our rating for sharpening manicure accessories. Since the manicure tool often dulls, this machine, weighing only 1 kg, will always help you to have a sharp cutting edge, and the stone will last a long time thanks to working with short blades.

CHAMPION C2001

Rating: 4.9

Professional grinder with 230 W power and 3000 rpm. Equipped with a 14.5×2.2 cm stone mounted on a straight shaft from an electric motor. The drive is located on a metal bracket with a drop-top. The horizontal metal bed has a vise slot for clamping the chain. The rotating emery is covered with a transparent cover for proper visibility and safety. Users in the reviews pay attention to a convenient scale by which it is easy to adjust the degree of impact of the stone on the teeth of the chain.

There are three adjusting screws for clamping the chain and adjusting the angle of the motor unit. The rear of the compartment has a perforation for heat dissipation. Although there are some backlashes in the design, according to the owners' feedback, they can be easily eliminated and the equipment set up for correct operation.

The machine is listed as one of the cheapest in the category compared to its peers. We recommend this machine for those who need to independently harvest a large amount of firewood for heating, and therefore the chain on the chainsaw needs to be adjusted regularly. Due to the low cost, the product will quickly pay off.

CHAMPION C2000

Rating: 4.7

Saw chain sharpener with a simple design and a weight of only 2 kg. The rotation is provided by an 85 W electric motor, which spins the emery to a speed of 4500 rpm. The thickness of the stone 4.5 mm allows you to sharpen even professional chains with a large pitch. According to reviews, it was noticed that the machine works very quietly, and its clamp reliably holds the inserted chain. But users don't have enough backlighting, so you'll have to take care of that separately. The model also does not have a full-fledged handle, but only a small protrusion – the pressure, in fact, is carried out behind the headband of the engine.

The experts decided to add this grinder to the rating as another affordable option for people who often use a chainsaw in their country. The machine will allow you to comfortably sharpen the chain, and not spend half a day using a file. It is especially good with its help to change the sharpening angle from 30 degrees to 10, which was noted by most of the owners.

Advantages

• rotation of the desktop from 0 to 35 degrees;
• economical power consumption 85 W per hour;
• sharpening wheel 10.5 cm;
• engraved scale for accurate setting.

disadvantages

• plastic bed;
• flimsy protective cover;

Enkor Korvet 472

Rating: 4.9

Product from a Russian brand with a powerful 370 W motor and belt drive. An asynchronous motor rotates a stone 2 mm thick and 100 mm in diameter at a speed of 3500 rpm. The machine is placed on a solid base and weighs 40 kg, so it does not rattle or move during operation. A scale on the turntable helps you set the desired sharpening angle. The reviews noted that the machine does not heat up and is suitable for operation all day.

The experts ranked the machine as the most convenient. The disc is securely fixed on a bracket that moves along two guides. Backlash is minimal here, which ensures high sharpening accuracy. When moving from one tooth to another, the disc is blocked from reverse rotation so as not to spoil the cutting edge by accidental movement. We recommend this grinder for large sawmills where the operator can work comfortably for a long time.

Advantages

• full steel body;
• powerful guides;
• weighty base, which does not have to be fixed;
• good air cooling for long-term operation.

disadvantages

• high price;

Kalibr Master EZS-110DM

Rating: 4.8

Russian-Chinese grinder for discs with a rotation speed of 5300 rpm. At the same time, the machine consumes only 110 W, since a rectifier is provided inside, and the machine then operates on direct current. Small dimensions and weight of 5 kg are due to the extraordinary design with a swivel guide, on the axis of which the disc is located. The stone is safely hidden in a plastic casing. The user's eyes are closed with a transparent screen, through which it is convenient to monitor the process. The owners recommend in the reviews to first train on a damaged disc in order to learn how to accurately set the adjustment angle, since it is very difficult here.

The model is included in the rating because it costs five times cheaper than analogues. But since there are backlashes in the design, it is optimal to use it for sharpening discs for sawing rough wood. This will help to easily restore the sharpness of the rig and accelerate the work.

Advantages

• diamond grinding wheel;
• suitable for disc diameters from 90 to 400 mm;
• about 100 positions for adjustment to achieve an exact machining angle;
• converts alternating current to direct current.

disadvantages

• the landing size of 20 mm will not allow putting on discs with a parameter of 16 mm;
• difficult to set up;
• there is play on the guides;
• inconvenient to change the angle of inclination of the axis (located under the motor).
