Bahco 230-SD Step Drill 13 Steps 5-35mm Titanium-Nitride Coated 230-SD

For making holes in thinner metal sheets

Titanium-nitride coated step drill with a surface hardness that makes the tool last 4 to 5 times longer than ordinary step drill bits. That same surface reduces friction, resulting in a tool that runs cooler and, in effect, self-lubricates while running dry

Drills holes in 13 steps from 5 to 35 mm

Shank 1/2" (12.7 mm)
