Leitz Boring & Drill Bits: Buying Guide
Precision boring bits for furniture and panel production — hinge holes, dowels, shelf holes, and through-bores. Solid carbide construction and round-spur geometry give tear-free edges even in glued, plastic-edgebanded panels.
How to Choose
- Confirm the drilling diameter and shank size (10 mm shank is standard on most boring machines).
- Check overall length (GL) and whether you need a through-hole or blind (dead) bore.
- Match the rotation — RL (right) or LL (left) — to your spindle.
- Choose brad-point/round-spur geometry for clean edges in coated and veneered panels.
Specs to Check
Best for point-to-point and through-feed drilling machines, CNC centres, and multi-spindle drill heads.
