40MM (1.575") ARBOR HOLE
(4/12/64 = 4 bolt holes which are 12mm 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.
HSS M2 DMo5 VAPOR STEAM TREATED BLACK OXIDE
Our cold saw blanks are made from M2 - DMo5 tool steel. During the manufacturing process they are heat treated and hardened to about 65 HRc, triple tempered, and press quenched to preserve their flatness. Every blade undergoes a strict quality control check. During this process, we test for runout on flatness, surface roughness, blade thickness, cracks, and scars. Flatness is checked at every point on the surface and roughness is checked via infrared deflection.
