Reduced Shank Cobalt End Mill (15mm Dia, 32mm Cut Length) for Maximum Rigidity and Fine Finishing in Heavy-Duty Machining in Canada.
The Snail Tools HSS Co Four Flute End Mill (15 x 16 x 32 x 92MM) is a specialized, high-rigidity tool designed to provide a large 15 mm cutting diameter while utilizing a common 16 mm tool holder (reduced shank concept). The four-flute geometry is optimized for maximum stability and minimal deflection, resulting in the finest surface finish during heavy finishing passes in tough materials, including steel, stainless steel, cast iron, and high-tensile alloys. 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 rigidity 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.
-
Reduced Shank Concept: Features a 15 mm Cut Diameter (D), a 16 mm Shank Diameter (d), and a substantial 32 mm Length of Cut (B), providing ample capacity for deep finishing cuts while fitting a standard holder size.1
-
Application: Ideal for production finishing, slotting, and profiling operations where rigidity, heat resistance, and a superior surface quality are paramount, especially in ferrous metals.
