How do I make sure this Leitz tool fits my machine?

Match the mounting (bore, shank, or HSK/hydro interface), confirm the maximum speed rating (n max / MAN) against your spindle speed, and order the correct rotation/hand (RL or LL) where applicable. Our team can verify the exact fit for your machine — just contact us with your model.

Should I choose carbide (HW) or diamond (DP) Leitz tooling?

HW tungsten carbide is versatile and resharpenable — ideal for solid wood and shorter runs. DP polycrystalline diamond costs more up front but lasts up to 100× longer on abrasive coated board, MDF, and composites, giving the lowest cost-per-cut on high-volume production.
