3/16인치 스터비 코발트 M42 드릴 비트, 짧은 드릴 길이, 머신 스크류 드릴, 미국산

These cut through hardened steel like butter compared to the cheap bits I've been burning through. The stubby 2-1/4" length is perfect for drilling out broken bolts in tight engine bays where a full-size bit won't fit. Ten bits for this price is a steal.

Bought these for tight spots under the hood where a full-length bit won't fit, and the cobalt M42 tips have held an edge through a dozen holes in mild steel without wandering. Ten bits in the pack means I'm not babying the one good drill anymore.

The stubby 2-1/4" length is perfect for tight spots where a regular bit won't fit, like drilling between a wall stud and a fixture. Cobalt M42 holds an edge way longer than the cheap bits I used to burn through. Ten of them for this price feels like a steal.
