Standard Cobalt End Mill (20mm Dia, 32mm Cut Length) for High-Rigidity Finishing in Heavy-Duty Machining in Canada.
The Snail Tools HSS Co Three Flute End Mill (20 x 20 x 32 x 104MM) is a robust, standard 20 mm diameter, high-rigidity tool designed for precision milling and finishing across a wide range of tough materials, including steel, stainless steel, cast iron, and high-tensile alloys. The three-flute design offers maximum stability, reduces deflection, and delivers a smoother surface finish, while the cobalt infusion ensures superior heat resistance for demanding industrial 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 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.
-
Dimensions: Features matching 20 mm Shank Diameter (d) and 20 mm Cut Diameter (D). The 32 mm Length of Cut (B) provides ample depth for industrial milling and finishing tasks.
-
Application: Ideal for production finishing, general slotting, and profiling operations where rigidity, heat resistance, and a superior surface quality are paramount, especially in ferrous metals.
