DIN338 Twist Drill Bit Set Metal Drilling Bit
M35/6542(M2)/4341 Twist drill bits are widely used to drill holes.A
cutting point is on the top of a cylindrical shaft with spiral
groove and chips will be removed through groove.HSS is one of tool
steel.It’s more hard and wear-heat than high-carbon steel as well
as the cutting speed.
HSS twist drill bits are widely used to drill stainless
steel,alufer,copper and other metals. They are suitable for
timber,pvc materials cutting as well.
1. HSS 4341/4241: Suitable for common metal cutting, like iron,
copper, alufer and timber etc.
2. HSS 6542(m2): suitable for all types of metal, like stainless
steel, iron, copper, alufer and wood etc.
3. M35: This type currently is the best one among HSS materials.It
largely improves its rigidity due to its 5% content of cobalt.It’s
suitable for cutting all kind of metals, like stainless steel,
iron, copper, alufer, cast iron and 45# steel as well as wood,
plastic etc.
118° and 135° split point
118 drill bits are more suitable for soft materials cutting,like
mild steel or cast iron.
135 drill bits are suitable for hard steel,especially for hole
diameter 4times as the drill bits’ diameter.The thick chips
produced when cut hard materials reduce the working hardening of
the cavity.
