uxcell Carbide Square End Mill, 3/8" Diameter AlTiN Coated 4 Flutes Milling Bit Cutter, for Carbon Steel Alloy Steel Titanium Metal, 3/8" Shank 1-3/4" Cut Length 4" Extra Long HRC55

Cutting Diameter: 3/8"Shank Diameter: 3/8"Cutting Length: 1-3/4"Total Length: 4"Material: Tungsten Carbide (Solid Carbide)Finish: AlTiN CoatedNumber of Flutes: 4Cutting Hardness: HRC50End Cut Type: Square EndCutting Direction: Upcut (Right Hand)Descriptions: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. Well-suited for machining abrasive materials like carbon steel, alloy steel, and titanium.Micro grain carbide mill bits offer high hardness, wear resistance, enhanced rigidity and excellent heat resistance. AlTiN (Aluminum Titanium Nitride) coating provides enhanced hardness, high oxidation resistance, and increased lubricity. Offers excellent performance in dry cutting applications and at high temperatures.Features precision ground cutting edges for clean, precise cuts, resulting in accurate machining and excellent surface finish on your workpiece. Up-cut spiral flutes lift chips upward and away from the cutting area, providing excellent chip evacuation. Large spiral design helps effectively remove chips during cutting, reducing clogging and improving chip evacuation. Universal chamfered round shank, good compatibility and easy to use. Use on standard milling machines, CNC machining centers, engraving machines and other high-speed CNC machine tools. 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.
