Steel cutting cold saw blades are a staple to any metal cutting workshop and are also handy for cutting pipes and tubes. The name comes from the process of transferring heat energy in the cutting process. At the time of cutting, blade and the metal surface remain cold, while heat is expelled in the chip.
Cold saw blades are the way to go if you are looking for an optimum finish with a super square and accurate cut. These blades will make sure that there is no secondary operation of re-facing or cleaning the cut surface. The most striking feature of the cold saw blades is that they can be re-sharpened with ease.
Steel Cutting Cold Saw Blades: Designed To Perfection
Made in Italy, all the blades are made of super high-speed steel with a high tungsten and molybdenum content. These elements of composition ensure that, after heat treatment, extremely high hardness and suitable tenacity is achieved. The right tungsten percentage is essential to create the correct quantity of very hard wear-resistant carbides to improve the tool life under high temperatures.
The tungsten increases the mechanical endurance of the tool, improving the cutting performance and preventing the austenite grain enlargement (In Material science, austenite grain growth is the increase in size of grains in a material at high temperature). The tungsten is also essential to guarantee the formation of a fine martensitic structure, and increases the tool tenacity, maintaining a high mechanical resistance. Vanadium is the element that forms the hardest, wear-resistant carbides amongst all other alloys.
Tips For Using Your Steel Cutting Cold Saw Blade
The most important thing to remember is to let the blade do the work. Forcing the blade through the material during cutting will decrease the blade’s life drastically. Below are some additional tips to extract the best performance out of your blade:
- Let the blade do the work. Applying too much pressure will increase chattering and vibrations leading to decreased blade life.
- Make sure all the clamps and screws and tightened to prevent any backlash.
- Make sure the cutting material is tightly clamped to the vise. Loosely placed cutting material will permanently damage the blade.
- When cutting stainless or alloy steel, reduce the speed of the blade. Use a blade with a smaller diameter and high pitch.
- When cutting non-ferrous material, use blades at higher speed with a larger diameter and fewer teeth.
