Features

Geometry Ball nose (R = D/2), 2 flutes
Neck Reinforced tapered: starts just below the cutting diameter and widens with a 0.5° to 2° taper up to the collar. It follows the wall draft and is more rigid than a cylindrical neck.
Diameters Ø 0.5 – 3 mm in tight tolerance; intermediate diameters and above Ø3 custom made
Usable length from 2 to 45 mm (up to 15 times the diameter)
Helix 30°, right-hand cut
Shank Ø 6 h6 with tapered collar
Materials Mould steels, quenched and tempered and hardened steels up to 65 HRC, stainless steels, cast irons, copper and aluminium
Construction Ultra-fine grain solid carbide, coating chosen for the material (high-silicon coating for hardened steels)

Dimensions in mm. For each diameter the usable lengths shown are available in 1 – 5 mm steps with four neck tapers. Other combinations, special radii and intermediate diameters custom made.

Why a tapered neck

  • Mould walls almost always have a draft: the tapered neck follows it and reaches the bottom without touching the wall.
  • For the same usable length the cross-section grows towards the shank: the tool deflects less, vibrates less and leaves a better finish.
  • Choose the taper closest to the draft of your walls: more taper, more rigidity.
