Reduced Shank Cobalt End Mill (19mm Dia, 38mm Cut Length) for High-Rigidity Finishing in Extreme Heavy-Duty Machining in Canada.
The Snail Tools HSS Co Three 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 concept). The three-flute geometry is optimized for maximum rigidity, high feed rates, and superior surface finish 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: 3 Flutes (Triple Flute) – Offers maximum tool rigidity, resulting in better control, reduced vibration, and a smoother surface finish, ideal for heavy finishing passes and applications requiring high stability 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.
-
Reduced Shank: Features a 19 mm Cut Diameter (D) with a 20 mm Shank Diameter (d). The 38 mm Length of Cut (B) provides substantial depth for industrial finishing and profiling operations.
-
Application: Ideal for production finishing, slotting, and profiling operations where rigidity, heat resistance, and a superior surface quality are paramount, especially in ferrous metals.
