4-Flute Corner Radius End Mill — Variable Helix
A radius at the corner makes the edge last. Variable helix keeps it quiet. The tool most shops settle on…
Ø3–20 mm, R0.2–3.0 · 4 · AlCrN
Corner Radius End Mills
Radiused corners that strengthen the cutting edge and resist chipping in interrupted cuts — the workhorse geometry for hardened steel and high-feed roughing.
4-Flute Corner Radius End Mill — R0.5
A fixed 0.5 mm radius corner, ground to ±0.01 mm, for production work where the radius is specified on the…
Ø6–16 mm, R0.5 · 4 · AlCrN
3-Flute Corner Radius End Mill — Aluminium
High-helix three-flute geometry with a radiused corner for aluminium, where chip clearance decides the finish.
Ø6–16 mm, R0.5–2.0 · 3 · Uncoated / polished
6-Flute Corner Radius End Mill — High-Feed
Six flutes, a generous radius and a strong core for high-feed roughing strategies where the machine can take it.
Ø8–20 mm, R1.0–3.0 · 6 · AlTiN
Corner Radius End Mill — Hardened Steel 60 HRC
For the top of the hardness range: an ultra-fine substrate and AlTiN coating that keep cutting where standard grades stop.
Ø4–16 mm, R0.3–2.0 · 4 · AlTiN
