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.
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.
