RUKO Solid Carbide Weldon End Mill 42mm, 4-Flute, DIN 844

Machining large-diameter profiles in steel, stainless steel, cast iron, and non-ferrous metals requires a cutter that combines rigidity, precision, and chip evacuation. The RUKO KEB-HM-Weldon-42,0mm solid carbide end mill addresses this with a 42 mm cutting diameter and Weldon shank for secure tool holding.

Who is it for

CNC machinists and toolmakers who need a reliable end mill for universal milling operations on a wide range of materials, from tough steels to softer non-ferrous alloys.

Main features

• Solid carbide (HM) construction for high wear resistance and cutting performance
• Weldon shank (DIN 1835 B) ensures positive locking and prevents slippage under high torque
• 4-flute design with 30° helix angle for efficient chip removal and smooth cutting
• Sharp cutting edge geometry suitable for universal machining
• Uncoated surface allows regrinding and is cost-effective for general use
• Right-hand cut with external coolant supply for standard machining setups
