Engineered for high-efficiency deep cavity milling, extended-reach profiling, and deep-pocket ramping, the Guhring Metric Long Series M42 Cobalt 3 Flute End Mill range delivers the ultimate industrial balance of red-hardness and structural toughness. Manufactured from premium 8% Cobalt High-Speed Steel (designated as M42 HSS-E), these heavy-duty long series slot drills feature a specialized 3-flute geometry that provides superior core rigidity to resist lateral tool deflection over longer overhang distances, while maintaining massive flute clearance valleys for rapid chip evacuation. Unlike brittle solid carbide alternatives that can fracture under structural vibration, the high-tensile elasticity of the premium M42 substrate absorbs heavy shock loads and harmonics without chipping. This series is the definitive workshop choice for reliable deep pocketing and slotting in work-hardening stainless steels, high-tensile alloy plates, titanium, and demanding structural fabrication setups.
