FAQ

Small bit drilling, drilling machine speed is fast or slow?

The two cutting edges should be the same length, and the cutting edge is usually between 8~12 degrees. Do not cut the cutting edge even lower than the back angle, so that the drill can not be drilled. In addition, the drill bit should be slightly sharpened so that the axial resistance of the bit during drilling will be reduced, so that the drill can save a lot of effort when drilling down.

What drill is used in stainless iron drilling?. What color?

The best is to make the stainless steel material of cobalt containing material with high speed steel drill, high-speed steel drill is cobalt containing silver, do not know the landlord of the silver white bit is not high speed steel containing cobalt, if not, you can buy only high speed steel cobaltiferous material drill (also called stainless steel special under the best bit), buy imported, not much of your money, the quality difference is too large domestic drill. Or if not, can change the drill bit Ti, Ti is abrasion resistant, average life is 3 times more than the standard twist drill

When the blade is in contact with the grinding wheel, it should be drawn back from the main cutting edge, that is, contact the grinding wheel from the edge of the drill bit and then slowly grind down the whole flank. Gently contact wheel bit penetration, advanced for less grinding, and observe the uniformity of discharge, timely adjustment of the size of the pressure on the hand, but also pay attention to the drill bit cooling, can not be allowed to wear too much, causing the edge to edge discoloration, annealing. When the blade temperature is high, the drill bit should be cooled in time.
