5Pcs Square End Mill 5/16" X 1" X 5/16" X 2-1/2" Tialn Coat 4 Flutes 45 Degree

TiAlN (Titanium Aluminum Nitride) coating provides high hardness, increased lubricity, and improved heat resistance. Performs well under high-temperature cutting conditions and provides good wear resistance. Micro-grain carbide mill bit has high hardness, high wear resistance, high strength, enhanced rigidity and high temperature resistance. Fully ground mirror body with high smoothness, 45 degree large helix angle for effective deburring and polishing, larger core diameter is not easy to break the edge. Precision ground cutting edges for clean, precise cuts. 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. It is a milling cutter for machining abrasive materials like carbon steel, alloy steel, and titanium. Applicable machines: CNC machining center, engraving machine, precision engraving machine and other high-speed machines. Universal chamfered round shank, good compatibility and easy to use. The longer the length of the tool clamped by the chuck, the better. Tips: Make sure the end mill is suitable for the specific application and material being processed. Use a suitable coolant or lubrication method during milling operations to dissipate heat and prolong tool life. Select an appropriate feed rate and cutting speed.
