Main highlights

This twist drill bit is usually able to run three to five times faster. Despite the higher price, the cost per hole is the lowest when using a cobalt drill as it can produce so many more holes.
The three-stage design can improve the efficiency of drilling stainless steel, aluminum, copper, plastic and hardwood.
The sufficiently sharp bit edge can cut the metal material into long strips of iron shavings instead of slowly grinding the material with a blunt drill.
Premium M42 8% Cobalt HSS Drill Bit Set, 68-70 HRC (Rockwell Hardness Scale), usually provides the best heat, wear and chip resistance and long tool life.

Main highlights

The twist drills for metal have optimal cutting behaviour, especially in all stainless steel, but are also suitable for all types of steel, cast iron and cast steel
The steel drill bits with special grinding and 130° tip angle ensure small metal shavings using the 'Quick Cut' geometry and are three times stronger than the drills with cobalt content
The shaft and spiral of the cylindrical drill bit for steel are hardened differently to reduce the risk of breakage
Thanks to the short, specially shaped spiral groove, the retracting effect of the HI-NOX HSS M2 metal drill is reduced, which is why the drill is ideal for drilling in sheet metal
Even under heavy loads, the HSS drill bits are extremely heat-resistant and stable, so that the material retains its hardness even at high temperatures and is not damaged

Main highlights

Versatile professional use: our drill bits are designed to effortlessly drill hard materials such as stainless steel, steel, sheet metal and cast iron as well as softer materials such as plastic, aluminium alloys and wood. Please note that these drill bits are not suitable for glass or ceramic.
Precision manufacturing: thanks to a 135° tip geometry, our drill bits ensure precise starts and reduce slipping on the surface. The fully ground body allows for faster drilling with fewer errors compared to conventional rolled drill bits, while providing excellent chip and heat dissipation.
Optimised spiral groove design: the fully ground spiral groove ensures quick chip removal, reduces friction and heat generation. This allows for faster, cooler and more efficient drilling, even in the most demanding conditions.
M35 COBALT STEEL: Our drill bits are made of high-quality M35 high-speed steel, which is significantly harder than conventional HSS. With a 5% cobalt content, they offer superior wear resistance, increased durability and longer life, making them ideal for demanding applications.
Improved heat resistance: our drill bits are designed to withstand high temperatures and maintain their hardness and cutting performance even in intense heat. This makes them perfect for long-term use in high-speed drilling applications without sacrificing performance.
