High Speed Steel Twist Drill Bits Metal Drilling Bit

High Speed Steel Twist Drill Bits Metal Drilling Bit

1. HSS twist drill bits are widely used to cut round holes.A cutting point is on the top of a cylindrical shaft with spiral groove and chips will be removed through groove.It can be divided into M35/M2(6542)/4341/4241 by the HSS material and The M35 one is the best one due to its additional 5% cobalt which can increase the HSS material’s capability to keep its high hardness under the high temperature generated in the drilling and mostly used for hard metal cutting as stainless steel, thick iron plate as well as wood and plastic etc.

2. M35 cobalt HSS twist drill bit owns the best features of rigidity and heat-wearable and has the twice service life than 6542(M2) one.They are widely used to drill various metal,wood,even stainless steel materials.

118° and 135° split points

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.
