PBU-E Ball End Mill Heads

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)
