2-Flute · TiSiN · HRC55 · Standard Reach
1mm 2-Flute TiSiN Solid Carbide Square End Millfor HRC55 Steel & Stainless
The 2-flute TiSiN variant offers maximum chip clearance for full-slot milling and deep pocketing in steel and stainless steel up to HRC55. Fewer flutes mean lower cutting forces and reduced heat accumulation in the cut, extending tool life in interrupted cuts, thin-wall features, and gang drilling operations. TiSiN coating prevents micro-chipping at high chip loads.
