About this item
- TiAIN coating: the TiAIN coating in industrial quality with very high hardness gives step drills a longer lifetime, higher processing speeds and excellent heat resistance. This coating has excellent heat, wear and corrosion resistance, as well as strong adhesion and low friction
- Made of high-quality M35 steel: HSS M35 steel enables efficient drilling in a wide range of materials, including stainless steel up to 3 mm thick, as well as iron, aluminium and other metals up to 5 mm thick. Optimised cone drill with deep double helix for better chip removal
- 15 steps (diameter 4-32 mm): our HSS stepped drill bit includes 15 steps from 4 mm to 32 mm, namely 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30 and 32 mm. It is multifunctional for pre-drilling, drilling, deburring and all other daily drilling needs
- 10 mm drill shank: thanks to the special production, our cobalt cone drill bit bits fit perfectly into all types of cordless screwdrivers and drills, especially in bench drills. The shank length is 24 mm and the shank torque no less than 1100 Nm
- Helpful tips: oil is needed at first use to give the auger an easy start and reduce friction. As the auger is a wearing part, it should be replaced regularly, especially if it is heavily loaded

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
