Product Description

 

Product Description

What sets High Speed Steel Twist Drill Bits apart from conventional drill bits is the material they are made of - high speed steel. This type of steel is specifically engineered to withstand high temperatures and high-speed drilling applications, making it ideal for drilling into tough materials like metal, wood, and plastic.
Featuring a twisted fluted design, these drill bits enable efficient chip removal, preventing clogging and overheating. This design also enhances the bit's strength and stability, ensuring accurate and precise drilling every time.

Our Advantages

1.Cobalt drill bits are more expensive than other drill bits, but if you regularly drill through metal, they are a good investment since they tend to last longer.
2.No center punch is needed-the aggressive 135° Quick-Cut points are self-centering and penetrate quickly with lesspressure. Will not "walk" or "wander".
3.Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance.

Product Application

To drill holes in various alloyed, unalloyed steel, rough metal , stainless steel, inox, iron, castiron,etc.
1, Fully ground drill bit 5% Cobalt HSS with 135degrees split point and flute type N.
2, Diameter tolerance h8 standard.
3, The cobalt content makes the bit harder and heightens temperature resistance,for work with hard metals such as stainless steel.
4, To drill holes in unalloyed and alloyed steels (up to 1200/mm2), stainless steel, cast iron.
5, The basic choice for industrial applications and the drilling of materials difficult to machine.
