Characteristics of specific models, as well as customer reviews can be studied on the Internet, on thematic forums and in social networks. Very often it is this information that becomes decisive for the buyer.

Types of saw blades

Saw blades are called special cutting wheels, intended for use in various carpentry equipment. IN Depending on the manufacturing technology, all saw blades are divided into several types.

Monolithic saw blades

Monolithic saw blades

Made from solid metal and exposed initial laser sharpening. At the heart of them almost always lies high carbon steel, characterized by maximum strength and reliability. Such discs are inexpensive and convenient to operation, and also allow sharpening if necessary;

Advantages

  • Low price;

  • Allow secondary sharpening during operation;

  • Durable and sharp;

  • High quality;

disadvantages

  • Quickly dull;

  • Wear when working with hard surfaces;

Carbide wheels

Carbide wheels

Composite models, the core of which is made of alloyed steel, and the cutting edge is a solder of high-strength tungsten or titanium. The result is similar the design is lightweight, very sharp teeth and ability to hold sharpening perfectly.

Advantages

  • High strength;

  • Quality performance;

  • Excellent sharpening even when working with hard surfaces;

  • Sharpness;

disadvantages

  • Expensive;

  • With a frenzy, return to its original severity practically impossible;

Saw blade selection options

saw blade selection criteria

Outer and rim diameters

You should select those models whose characteristics are completely suitable for specific conditions of use and applicable equipment. The bore diameter should correspond to the dimensions cutting device shaft, the outer diameter should be slightly less mounting slot;

Number of teeth

  1. Disks with a small number of teeth are considered rough, they give rough cut, however, chips are well removed from the sawing area. Typical the number of teeth of the rough disc – from 10 to 40;

  2. Disks in large numbers, from 60 to 90, teeth – fine, designed to make accurate and accurate cuts wood;

Tooth shape and size

  1. Homogeneous straight teeth are used for processing plywood, Chipboard and even aluminum;

  2. Dissimilar teeth bent from the center line in different directions, designed for cutting soft and hard wood, as well as Fiberboard and particleboard;

  3. Small trapezoidal teeth designed for cutting soft metals and plastic;

  4. Large teeth and a large pitch between them are a sign of discs for longitudinal cutting of solid wood;

  5. Small and frequent teeth are direct evidence of a circle, designed to perform a transverse cut;

Disc thickness

A parameter that determines the thickness of the cut line. Standard thickness the disk is 3.2 millimeters, however on sale you can find both thinner and thicker models. First wide used for cutting valuable wood species. The second is for work with laminate and various metals;

Features of choosing a saw blade for wood

A correctly selected saw blade for wood must have following characteristics:

  1. Monolithic construction;

  2. 30-40 teeth for a rough saw and 60-80 for a smooth fair seam;

  3. The thickness of the disk is 2.8-3.2 mm;

  4. The design of the teeth of a heterogeneous shape, each of which is rejected at an angle of 7-9 degrees from the vertical;

  5. Landing and outer diameter corresponding to the dimensions devices

Features of the choice of a saw blade for a circular saw

  1. The disk structure is carbide;

  2. The number, size and structure of the teeth are selected based on the need to work with specific materials and type of wood. More delicate work requires thin disks with a large number of teeth, the implementation of the rough saw allows the operation of more a thick circle with a few large teeth and a significant step between them;

  3. The diameter of the disk and the size of the mounting hole are selected for dimensions of a specific device;

  4. Thickness – 3.2 and more than a millimeter;
