BAHCO Step drill, 4 to 22mm 229-SD

Sizes: 4-6-8-10-12-14-16-18-20-22 mm
Common Characteristics
- For making holes in thin 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 whilst running dry
- Drills holes from 4 to 22 mm in 2 mm increments
- Shank 3/8" (10 mm)
