Stepped cone drill bit for very thin sheet metal.
Titanium-nitride coating with a hardened surface allows
the product to last 4 to 5 times longer than a regular drill bit.
This treatment reduces friction, allowing the tool to remain cool
and self-lubricate in dry materials.
Sizes 4-12 mm with 1 mm step. Shank 1/4” (6 mm)
