Reduced Shank Cobalt End Mill (13mm Dia, 26mm Cut Length) for High-Rigidity Finishing in Harder Metals in Canada.
The Snail Tools HSS Co Three Flute End Mill (13 x 12 x 26 x 83MM) is a specialized, high-rigidity tool designed to provide a large 13 mm cutting diameter while fitting into a smaller 12 mm tool holder (reduced shank). The three-flute geometry is optimized for stability, high feed rates, and superior surface finish 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: 3 Flutes (Triple Flute) – Offers maximum tool rigidity, resulting in better control, reduced vibration, and a smoother surface finish, ideal for precision profiling and 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 machining.1
-
Reduced Shank: Features a larger 13 mm Cut Diameter (D) with a reduced 12 mm Shank Diameter (d). This allows the use of a larger cutter diameter in machines limited to $12\text{mm}$ collet sizes.
-
Application: Ideal for general finishing, slotting, and profiling operations where rigidity, heat resistance, and a superior surface quality are paramount, especially in ferrous metals.
