The HSS bit is a good all-rounder when it comes to drilling steel. It can be used on most materials. HSS (High Speed Steel) is the kind of tool steel used in the manufacture of these bits.
The black oxide coating provides heat resistance and lubricity as well as corrosion resistance.
The 118 degrees cutting point makes it a general purpose bit for drilling into wood, plastics, and milder steel types.
General tips:
• Use slow rotation speed to prevent overheating
• Use start-stop drilling action
