Description

Precision engineered steel bits with 2-flute design and tapered cutting edges allowing for de-burring or chamfering of the hole drilled. Included in the range is a quick-change, hex shank and round. 
Titanium coating protects the drill bits from corrosion and rust. Also provides friction reduction which makes it easier to do multiple drills on surfaces such as plastic, aluminum, copper, stainless steel, and other types of sheet metal.
With two-flute design, bit drills faster and more smooth.
