Hosco Japan H-TLDB27086 step drill for tuners, 8.6mm and 7.0mm diameter

Step drill bit for installing vintage/Kluson style tuners.

- Shank: 8.6mm diameter
- 7.0mm and 8.6mm diameter holes are drilled at the same time

All of our step drill bits are made of HSS (high speed steel) and promise a fine job for making tuner holes. The drill bit blade is especially designed to drill hard woods like maple.
