Leitz Router & CNC Bits: Buying Guide
Solid tungsten-carbide and DIAMASTER PCD diamond router tooling for profiling, trimming, nesting, and boring on hand routers and CNC machining centres. Diamond tooling delivers up to 100× the edge life of carbide on coated board and composites.
How to Choose
- Confirm the shank diameter (6, 8, 10, 12 mm or 1/2") matches your collet.
- Match cutting diameter and cutting length to the profile and material thickness.
- Pick the spiral direction — up-cut clears chips, down-cut leaves a clean top edge, compression gives clean faces on both sides of coated panels.
- Choose HW for solid wood and short runs; DP (diamond) for MDF, laminate, and high-volume nesting.
Specs to Check
Best for CNC routers, machining centres, point-to-point, and hand-held routing.
Sharpen It, Don't Replace It
Solid-carbide spiral bits can typically be resharpened two to three times before retirement, restoring a factory-sharp cutting edge for a fraction of the cost of a new bit. Our spiral bit service is precision CNC grinding that preserves the flute geometry — not a hand touch-up.
