DIN338 M35 Cobalt Twist Drill Bits Metal Drilling Bit For Hardened
Steel
M35 cobalt metal drill bit is the most widely used in metalworking.
metal drill bit is mainly composed of the cobalt metal drill bit
and the shank of the drill. There are two spiral grooves in the
working part drill bit,making cutting faster and less powerful,
cutting stainless steel more precisely. The inability to penetrate
while working indicates that the drill bit is blunt. Solution:
Re-grind the drill bits point and the cutting edge of the drill
bits to make it sharp.
