13 best diamond blades

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 the world of cutting tools, tooling plays a decisive role because of the speed of the process, the ability to cut hard materials and the cost of the consumable part. Diamond blades take the leading place here, as they are characterized by increased hardness of the cutting layer and a long service life. Because super hard carbon is superior to other materials, it can cut stone, concrete, ceramics, granite, brick and even metal.

But on sale there is a large selection of similar products that differ in the shape of the cutting edge, thickness and design. To make it easier to navigate in such a variety, our experts have prepared a rating of the best diamond blades for different materials. We took into account the characteristics of the cutting elements and the feedback from experts, as well as from ordinary users. All this will help you get a complete picture of the best discs and find the right one for specific jobs.

The best diamond blades for concrete and stone

Products in this category are the most popular. They come in handy when chipping walls for wiring, cutting out door and window openings, dismantling wall partitions and laying communications. Such discs are installed in cutters (electric or gasoline), wall chasers, furrow makers, angle grinders.

Husqvarna 5748362-03

Rating: 4.9

In the first place in the rating is a disc from a Swedish brand. This is an accessory for professional tools in the form of gasoline-type water-cooled cutters. The cutting element is made of high-strength steel and equipped with 15 long diamond teeth, 8.5x40x2.4 mm in size. This configuration at a diameter of 230 mm allows you to quickly cut through hard concrete, brick and other building blocks. 15 grooves with a round base provide compensation for thermal expansion and remove dust from the cutting area. Masters in the reviews praise the product for its 'vitality'. Having bought a couple of discs once, it will be possible to provide yourself with equipment for many years with regular use at construction sites.

Our experts ranked the rig in the first place in the rating as the best for phased cutting of walls up to 40 cm thick. The saw part easily sinks into concrete and brick, so making openings or dismantling partitions will not take much time.

Advantages

• the set includes two disks at once;
• long service life;
• will not turn on the shaft due to two additional holes for the pins;
• 15 diamond teeth;
• deep grooves for temperature and dust removal.

disadvantages

• high price;
• every 15 minutes of continuous operation, let it cool;
• a special mount for hand cutters (CnB) will not allow you to install the disc on the grinder;
• water cooling required.

Bosch 2608603241

Rating: 4.8

In second place in the rating is a product from the German manufacturer Bosch. The diamond disc is produced in a set and sold at once in 10 pieces. The equipment is designed to work with a grinder with a 2.2 cm seating shaft. The cutting wheel is made with a diameter of 15 cm and is equipped with 9 teeth with a turbocharged cutting technology (accelerated temperature removal through deep grooves). Diamond spraying has a triple layer, so when one diamond wears off and falls off, it is replaced by another, without sacrificing cutting performance.

Our experts rated the diamond blade as the best for a compact angle grinder to quickly cut a hole in a wall for an electrician or pipe. Due to 10 pieces in a set, such a purchase is a one-time, since the discs will last for 10-15 years, which is what the masters like in the reviews. Another 1 cm tooth height surpasses the performance of other manufacturers, so it has no equal in cutting speed and heat removal. This is confirmed by the permissible speed indicated on the packaging – 10200 rpm.

Advantages

• universal fit diameter;
• does not need water cooling;
• due to the thickness of 2 mm, it is resistant to breakage;
• 10 pcs per set.

disadvantages

• high price;
• not everywhere you can get it due to the small diameter;
• in some cities it is difficult to buy by the piece.

GRAFF GDD 18 350.10

Rating: 4.7

The third place in the rating is a diamond disc from a Belarusian company. Its price is significantly lower than other European brands. Despite this, the wheel has a diameter of 35 cm and is equipped with 24 diamond-coated teeth. The cutting part has a section of 3.4 mm, which allows you to confidently pass not only bricks, but also thick paving slabs, as well as curb blocks. The diamond compound is integrated into the metal by thermal pressing, which increases the degree of bonding. In the reviews, the owners note that the disc is well balanced, cuts smoothly and quickly.

Our experts liked the disc for its versatility, for which it was included in the rating. It can be installed on both handheld cutters to cut openings and stationary stone cutting machines for cutting blocks. Thanks to the turbocharged design, dry cutting is allowed, but the diamond tooling is also designed for watering, which prolongs the service life. The thick, diamond-coated 3.4 mm teeth take an especially long time to grind.

Advantages

• does not 'walk' during cutting;
• can be used at speeds up to 5400 per minute;
• suitable for any type of cut;
• applicable to manual and machine tools.

• the landing size of 2.54 cm does not fit the shafts of all machines.

PRACTICE 030-771

Rating: 4.6

The fourth place in the rating belongs to a disc from a Russian manufacturer. The product is positioned as a turbo segment, that is, 12 teeth are also divided into parts to better cool. Tooling with a diameter of 15 cm is designed to work with a small angle grinder. Due to the special design, such a diamond-coated disc is allowed to cut not only brick, but even reinforced concrete (with metal rods inside). Therefore, the circle is used regularly when working in the armopoyas area, trimming puffs and thin curb stones. For the price, the disc is a worthy alternative to expensive brands.

This diamond blade is structurally different from other models, for which it is included in the rating of the best. Instead of short, straight grooves, the circle has long slots cut at an oblique angle. Its diamond spraying is not continuous, but serrated, which allows air flow not only along the grooves, but also between the cutting edge. This design contributes to more efficient cooling, which users agree with in the reviews.

Advantages

• affordable price;
• improved cooling;
• standard mounting diameter for the grinder 2.2 cm;
• application is allowed at speeds up to 10200 per minute.

disadvantages

• the small diameter of the circle is only suitable for thin walls;
• absolutely cannot be cooled with water.

BIZON 0515001

Rating: 4.5

The fifth place in the rating was taken by another product from a Russian manufacturer. This is a diamond disc with a diameter of 23 cm and a thickness of 2.2 mm. The base is made of tool steel with non-ferrous metal oxide. The cutting part is represented by synthesized diamonds in an amount of at least 30%. The designers have provided compensation holes in it, which contribute to the accelerated removal of construction dust from the cutting zone. The wheel has no pronounced teeth, but the cutting edge is raised, due to which the turbocharging effect is achieved. Thanks to the weight of 360 g, the rig is less felt on the grinder. Users in the reviews note the easy cutting of strobes with its help.

This is the cheapest disc in the rating category. If you need to disassemble the partition at home or carry out new wiring, then it will be enough for a one-time project, and you will not need to buy an expensive analogue. The blade is suitable for wet cutting, which increases its productivity – in this case, you can work without interruption.

Advantages

• suitable for rotation at 6600 rpm;
• any type of cut (dry or wet);
• affordable price;
• improved design technology for dust extraction.

disadvantages

• cannot cope with SHA-8 bricks;
• increased voicing during work;
• wears out faster than imported analogues;
• only suitable for grinders.

The best diamond discs for metal

Diamond brazed tooling is used for cutting metal, as an alternative, instead of abrasive discs. Unlike compressed abrasives, diamond blades emit less sparks and do not shrink or break during operation, which improves safety. Depending on the diameter, they are used for cutting pipes, profiles, angles and sheet steel.

Hilberg Super Metall (350х25.4 mm) TRIO-DIAMOND 520350

Rating: 4.9

In the first place of the rating, in the category of diamond discs for metal, is the product of the Russian brand. The tooling has 24 complex shaped teeth, each equipped with three cells, which facilitates the removal of metal dust. The grooves between the teeth allow the steel to expand from heat so that the circle does not bite into the material. Thanks to the grooves, the disc is regularly ventilated to remove the temperature. Diamond grit is vacuum-brazed to the steel, so it does not fall off. Users in the reviews like the 'omnivorous' cutting element, which can handle cast iron, copper, carbon steel, stainless steel.

In our opinion, the product has earned a place in the ranking as the best for cutting pipes in a cutting machine.

Best diamond discs for granite

To process granite, other diamond discs are used in design. This material is harder than stone or concrete and therefore requires a high diamond coating. But unlike them, granite forms less dust, and the equipment does not need a large number of expansion joints. Granite cutting wheels are used to trim or cut natural stone, basalt, bacor and clinker.

MESSER 01-26-230

Rating: 4.9

The first place in this rating category is assigned to a product from Messer. This is a domestic brand that produces premium products that can compete with European counterparts. The diamond tool has a diameter of 230 mm and a thickness of 1.6 mm. This is considered an ultra-thin metric to promote high performance. The solid working part is supplemented with embossed notches that improve the removal of dust from the cutting zone, for which the product is praised in reviews.
