General Purpose & Thunder End Mills
For milling mid-hardness materials (HRc 10-30), Thunder End Mills deliver consistent
performance across general-purpose applications. Metric (Ø1mm – Ø50mm) and
imperial (1/16"–1") sizes are offered with uncoated or TiN coatings for cost-effective
machining.
Classified under ISO 513 group P, Thunder End Mills feature helix angles of 30°–40° and 2–4 flutes. Sharp corners and radii up to 1.5mm ensure flexibility, while h6 shank tolerances guarantee precision.
