Exchangeable-Head Milling Cutters
PBU-E Ball End Mill Heads
General Specifications
Solid carbide exchangeable milling head — 4-flute ball-nose end mill head. Screws into any TE, WE or SE holder with the matching E-size connection.
- One holder takes flat, corner-radius and ball-nose heads — change the head, not the tool.
- Heads can be changed on the machine.
- Uses far less carbide than a solid end mill — about 70% less for a 100 mm long, 20 mm flute-length tool.
- Taper-and-thread connection maximizes contact area between head and holder while keeping concentricity stable.
- End Type: Ball nose
- Flutes: 4
- Helix Angle: 25°
- Connection: Taper thread lock, E10–E20
- Sizes: Ø10–20 mm, 8 sizes (metric)
