Stepped Precision Cobalt End Mill (8mm Dia, 18mm to 45mm Cut) for High-Speed Machining of Aluminum and Non-Ferrous Metals in Canada.
The Snail Tools HSS Co Single Flute End Mill (8 x 8 x (18 x 45) x 100MM) is a specialized tool featuring a stepped or variable length of cut design, intended for highly efficient, high-speed material removal, particularly in aluminum, brass, and plastics. The single flute design allows for maximum chip clearance and evacuation, crucial for preventing material adhesion and ensuring a smooth finish. This cutter provides superior rigidity during intricate and deep CNC applications across Ontario and the GTA.
Key Features & Optimized Performance
-
Design: 1 Flute (Single Flute) – Provides the largest chip valley, essential for very high feed rates and fast evacuation of soft materials, minimizing material sticking and friction.
-
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-speed machining.
-
Variable/Stepped Cut Length: The 18x45MM notation suggests a cutting length that extends from a minimum of 18mm up to a total of 45mm (Length of Cut, B), optimized for different depths, contouring, or specific progressive milling geometry.
-
Balanced Dimensions: Features matching 8 mm Shank Diameter (d) and 8 mm Cut Diameter (D), offering a balance of stability and clearance for deeper, continuous cuts.
-
Application: Ideal for profiling, intricate slotting, and deep routing in non-ferrous metals and plastics, delivering an exceptionally clean surface finish.
