About this tool

Three flutes and a deep, polished chip gullet — the geometry that stops aluminium from welding to the edge. Run it hard: this tool is designed for high spindle speeds and generous feed rates.

Where it works

Aluminium and other non-ferrous materials, plastics and composites. Ideal for profile cuts, slots and pockets where chip evacuation is the limit rather than the tool.

Cutting data — starting point

Starting values for a rigid setup with a good coolant supply. Treat them as a first trial, then adjust to the machine, the holder and the actual condition of the material.

Work material Cutting speed vc Feed Depth of cut
Aluminium (N) 300–600 m/min 0.05–0.12 mm/tooth 0.5×D
Aluminium 7075 (N) 250–450 m/min 0.05–0.10 mm/tooth 0.4×D
Plastics (N) 200–400 m/min 0.05–0.10 mm/tooth 0.5×D

What you can specify

  • Diameter, corner radius and flute count ground to your drawing
  • Coating — AlCrN, AlTiN, TiAlN, DLC or uncoated, matched to the workpiece
  • Shank — h6 ground, HA / HB / whistle-notch
  • Laser-marked part number, or blank shanks for distributor stock

Not sure about the geometry? Send the drawing or a photo of the part. We recommend the profile, the coating and the starting cutting data — and quote from there.

Why it works

  • Polished flutes and a 45° helix clear soft chips fast
  • Wide chip room stops the built-up edge that ruins aluminium finishes
  • Uncoated surface keeps the edge sharp rather than slippery
  • Centre-cut for ramping and helical entry
