Precision Cobalt End Mill (5mm Dia, 13mm Cut Length) for Maximum Rigidity and Fine Finishing in Harder Metals in Canada.
The Snail Tools HSS Co Four Flute End Mill (5 x 6 x 13 x 57MM) is a medium-fine diameter, high-rigidity tool designed for precision finishing operations, particularly in steel, stainless steel, and tough alloys. The four-flute design provides the maximum possible tool rigidity and engagement, resulting in the finest surface finish and highest stability during demanding finishing passes. This cutter features a cobalt infusion for superior heat resistance, making it ideal for accurate CNC finishing applications across Ontario and the GTA.
Key Features & Fine Finishing
-
Design: 4 Flutes (Quad Flute) – Offers maximum stability and minimal deflection, resulting in the highest quality surface finish and longest tool life, especially when performing peripheral milling and finishing operations.
-
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 machining of tougher metals.
-
Stabilized Shank: Features a slightly larger 6 mm Shank Diameter (d) than the cutting diameter, providing enhanced stability and rigidity for the 5 mm Cut Diameter (D), crucial for minimizing deflection and improving accuracy.
-
Application: Ideal for profiling, shallow slotting (in lighter materials), and high-quality finishing passes where tool stability and surface integrity are paramount in ferrous metals.
