About this tool
High-feed milling trades depth of cut for feed rate, which only works if the tool can carry the chip load. Six flutes and a protected corner let you keep the feed high in materials that would normally slow the operation down.
Where it works
High-feed roughing in hardened steel, tool steel and cast iron. Best on machines with the power and rigidity to run the strategy properly.
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 |
|---|---|---|---|
| Hardened steel 45–55 HRC (H) | 120–180 m/min | 0.02–0.05 mm/tooth | 0.3×D |
| Alloy steel (P) | 220–300 m/min | 0.03–0.07 mm/tooth | 0.5×D |
| Cast iron (K) | 180–260 m/min | 0.03–0.06 mm/tooth | 0.4×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
