Surface Of Treatment(Coating):

Steam Treated

This is currently the most common surface treatment for circular saw blades. The steam treatment creates a hard oxide layer on the blade and is the simplest “coating” available. It is used for general cutting applications, except for aluminum, copper, brass and their alloys.

Goldface (TiN – Coating)

The GOLFACE coating gives the blade a great surface hardness. The high oxidation temperature, together with other positive characteristics, makes it possible to work at cutting and feed rates approx. 50% higher than with an untreated blade. Cutting times are reduced and blade life is increased. GOLDFACE blades are suitable for cutting of mild steels (500 – 750 N/mm2).

Speedface (TiCN – Coating)

This is a multi-layer coating with a low friction coefficient that offers an excellent finish at very high cutting and feed rates. It can be used for hard steels (800 – 1000 N/mm2), for copper and brass alloys and for extremely abrasive materials where the phenomenon of “chip welding” can be a problem.

Bestface (CrN - Coating)

Characterised by a high surface hardness and low friction coefficient (the lowest of all), this coating is particularly suitable for cutting pasty materials such as copper, brass and bronze. Thanks to its high corrosion resistance this coating is also ideal for some plastics and applications where high temperatures and corrosion phenomena could develop.

Activeface

High performance coating for cutting high tensile strength materials, stainless steels and abrasive materials. Thanks to its high oxidation temperature (approx. 700°C) and low thermal conductivity, this treatment is suitable for dry-cutting at relatively high cutting speeds

Tip:How to Choose the Right Cold Saw Blade

Cold saws are a type of circular saw used for cutting wood and metal objects. Unlike traditional saws, cold saws transfer heat back into the blade rather than into the object being cut. These tools are primarily used for cutting sheet metal and metal pipes, but they may also be used by woodworkers and other professionals. To ensure smooth and safe cuts, buyers should choose saw blades carefully. When selecting cold saw blades, consider factors like size, tooth design and material to find the right blade for your needs.

Compare blade materials. Band saw blades come in three basic varieties, including carbon steel, high speed steel (HSS) and tungsten carbide tip. According to Tool Center, carbon blades are the most economical of the three, and are sufficient for most basic cutting jobs. HSS blades are more durable than carbon steel and have a longer lifespan in general. Tungsten carbide blades offer a high level of strength and durability, as well as the fastest cutting speed and longest lifespan of the three materials.

Choose the thickness of cold saw blades based on the diameter of your saw's mounting wheel. Most blade manufacturers provide a standard sizing chart, or you can reference the chart at the Tool Center website (see Resources). The smaller the mounting wheel, the thinner your blade should be. For example, a wheel that measures 6 inches or smaller requires a blade of only 0.014 inches. When in doubt, choose the thinner of two potential blades to maximize the life of the blade.

Match the diameter of the blade to the requirements for your cold saw. Check your owner's manual to find the correct blade diameter, or take your old blade to a local supplier and ask for help in finding the correct size.

Look at the tooth design, or tooth shape for each blade. According to Sterling Machinery, standard tooth designs are the best choice for fragile materials and are also a good option for general-purpose cutting. Skip-tooth blades provide the smoothest and fastest cuts for wide or large objects, while hook-tooth units are the most efficient for cutting soft metals like aluminum.

Find the pitch rating for each blade, measured in teeth per inch (TPI). According to Detroit Band Saw Works, the optimal TPI ranges from 6 to 12 depending on material. Soft or narrow materials require very fine blades, which will have a relatively high TPI. Wide or dense materials require coarse blades with a low pitch. The lower the TPI, the more coarse the blade will be.

Check the tooth set pattern. Regular blades, also known as raker pattern blades, feature single alternating teeth that are offset to opposite sides of the blade. According to Sterling Machinery, raker patterns provide the most uniform cuts and are best for cutting curves and contours. Wavy pattern blades feature several adjacent teeth set to one side of the blade, with the next group of teeth set to the opposite side to form a wave pattern. This design places the least amount of stress on the blade and can help prolong the life of most blades.
