Step drill, 5 to 35mm BAHCO 230-SD

Sizes: 5-13-15-17-19-21-23-25-27-29-31-33-35 mm
Common Characteristics
- 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)
