250 x 2.5 x 40 HSS M2 DMo5 Cold Saw Blade

250MM (9.843") DIAMETER 2.5MM (0.098") THICKNESS 40MM (1.575”) ARBOR HOLE Please verify you order the correct arbor hole size. If your machine takes a 250mm diameter blade AND has a 40mm arbor, this blade is guaranteed to have the appropriate bolt holes to fit your machine with no issues. Most cold saw machines will have a model number such as CS-250, which will signify the diameter of the blade that the machine uses. BOLT HOLES: 4/12/64 + 2/9/55 (4/12/64 = 4 bolt holes which are 14mm in diameter on a 64mm bolt circle) The bolt circle is the distance from the center of one pinhole to the center of the other pinhole directly across the arbor hole If you are unsure of how many teeth you need for your application, try using our tooth count calculator by clicking here (new window or tab will open). HSS M2 DMo5 COLD SAW BLADES Our cold saw blades combine HSS (High-Speed Steel) M2 and DMo5 steel, both renowned in manufacturing and machining. HSS M2, enriched with tungsten, molybdenum, vanadium, and carbon, stands out for its toughness and wear resistance at elevated temperatures. It is widely applied in drills, taps, milling cutters, and tool bits necessitating high cutting speeds and temperatures. DMo5, a high-alloy cold-work tool steel or AISI M2 modified, offers exceptional wear resistance, hardness, and toughness crucial for cold work tasks like crafting cutting and punching tools, as well as dies for blanking and forming operations under high stresses. While both materials excel in various machining and cutting scenarios, their integration in cold sawing enhances their performance. VAPOR STEAM TREATED BLACK OXIDE All cold saw blades used to cut steel products should have a coating. The most common coating is black oxide, sometimes referred to as vapor steam coated. The coating is most important to help prevent galling. Galling is caused by friction between sliding surfaces, most commonly found in metal on metal applications when there is inadequate lubrication between the surfaces. The combination of the coated blade and your flood coolant will prevent this issue. All blades are ground in the US on advanced computer numerically controlled (CNC) grinding equipment made specifically for manufacturing our blades to our specific standards by industry experts with over 40 years of industry experience.
