Reduced Shank Cobalt End Mill (19mm Dia, 38mm Cut Length) for Maximum Rigidity and Fine Finishing in Extreme Heavy-Duty Machining in Canada.
The Snail Tools HSS Co Four Flute End Mill (19 x 20 x 38 x 104MM) is a specialized, large-diameter tool designed to provide a large 19 mm cutting diameter while fitting into a standard 20 mm tool holder (reduced shank design). The four-flute geometry is optimized for maximum rigidity and minimal deflection, resulting in the finest surface finish during heavy finishing passes in tough materials, including structural steel, difficult alloys, and high-tensile cast iron. The cobalt infusion ensures superior heat resistance, making it essential for precision finishing applications across Ontario and the GTA.
Key Features & Precision Finishing
-
Design: 4 Flutes (Quad Flute) – Offers maximum tool stability and high engagement, resulting in better control, minimal vibration, and a superior surface finish, ideal for high-speed finishing passes in hard materials.
-
Material: HSS Co (High-Speed Steel with Cobalt) alloy construction ensures superior hardness, allowing the cutter to maintain its sharp edge and structural integrity during high-temperature and heavy-load machining.1
-
Reduced Shank: Features a 19 mm Cut Diameter (D) with a 20 mm Shank Diameter (d).2 The 38 mm Length of Cut (B) provides substantial depth for industrial finishing and profiling operations.
-
Application: Ideal for production finishing, precise contouring, and profiling operations where high rigidity, heat resistance, and a superior surface quality are paramount, especially in ferrous metals.
