High Speed Steel:
High speed steel construction provides ultimate durability and the titanium coating ensures a longer service life so that the drill bits last through multiple uses.
The split point tip and twist design increases cutting speed while easy self centering prevents walking. Say bye to all those chips and particles, with the twist design the drill bit can quickly clears them out, and leaves a clean, smooth hole.
