The Snail Tools HSS Co Four Flute End Mill (8 x 8 x 19 x 63MM) is a standard $8\text{mm}$ diameter, high-rigidity tool designed for precision finishing operations across a wide range of materials, including steel, stainless steel, cast iron, and general 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 on ferrous metals.
-
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
-
Dimensions: Features matching 8 mm Shank Diameter (d) and 8 mm Cut Diameter (D). The 19 mm Length of Cut (B) provides ample depth for common milling and finishing tasks.
-
Application: Ideal for profiling, shallow slotting (in lighter materials), and high-quality finishing passes where tool stability and surface integrity are paramount.
