HARFINGTON 5pcs Carbide Square End Mills 8mm (5 /16 inch) Dia 8mm (5 /16 inch) Shank 100mm (4 inch) Extra Long HRC55 TiSiN Coated Micro-Grain Tungsten Carbide 4 Flutes Milling Bit Cutter

Features

• Size - Cutting diameter: 8mm / 5/16" (right hand); shank diameter: 8mm / 5/16"; cutting length: 35mm / 1-3/8"; total length: 100mm / 4" (extra long); cutting hardness: HRC55; end cut type: square; helix angle: 35 degree; bending strength: 3900N/mm2.
• Material - TiSiN (Titanium Silicon Nitride) coating offers high hardness, excellent oxidation resistance, and improved toughness. 0.6m micro-grain carbide mill bits has high hardness, high wear resistance, high strength, enhanced rigidity and high temperature resistance. It is a milling cutter for high hardness and high-speed cutting applications.
• Features - Fully ground mirror body with high smoothness, 35 degree large helix angle for effective deburring and polishing, larger core diameter is not easy to break the edge. Large spiral design helps effectively remove chips during cutting, reducing clogging and improving chip evacuation.
• Applications - Square end mill can create slots (keyways or internal grooves), straight or square edge features, flat smooth surfaces, holes or for roughing, finishing and side milling operations. Suitable for high-speed machining and can process a variety of materials, including hardened steel, stainless steel and cast iron.
• Notes - Applicable machines: CNC machining center, engraving machine, precision engraving machine and other high-speed machines. The longer the length of the tool clamped by the chuck, the better. Use a suitable coolant or lubrication method during milling operations.
