Product Details

DIN338 Oxide Black Jobber Drill Twist Drill Bits For Iron Drilling

1. Premium Raw Material: Made of high speed steel for strength and durability
2. Package: Supplied in a pvc box or metal case for easy storage and transportation
3. Widely Used: The 135° fast cutting point is automatically centered and penetrates quickly with less pressure,The drill kit meets all your requirements including all common size specifications for Wood/Cast Iron/Aluminum Alloy/Plastic/Fiberglass

4. 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.
5. HSS is one of tool steel.It’s more hard and wear-heat than high-carbon steel as well as the cutting speed.
6. 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.

Choose the most suitable HSS twist drill bits according to the processing requirement

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.
