10pcs End Mills CNC Router Bits 1/8" Shank 1mm Blue Coating Tungsten Carbide Milling Cutters for PCB Acrylic Wood Aluminum Metal <p>Size - Cutting Blade Diameter: 1mm / 0.039"; Shank Diameter: 3.175mm / 1/8"; Cutting Blade Length: 10mm / 3/8"; Total Length: 38mm / 1-1/2"</p> <p>Material - Made of premium tungsten carbide, the CNC router bits feature excellent hardness, sufficient bending strength, wear resistance, durability and good performance in milling and cutting to ensure high working efficiency.</p> <p>Features - The blue coating increases hardness, reduces friction and heat, improves lubrication and protects bits from rust and corrosion. It provides longer tool life, higher wear resistance and smoother chip evacuation. The surface is very clean, neat, and flawless.</p> <p>Applications - Suitable for PCB, plastic, wood, aluminum, copper, stainless steel. Ideal for precision milling, profiling, grooving, engraving, and other CNC machining operations. Sharp cutting edges ensure clean cuts, accurate dimensions, and minimal vibration.</p> <p>Note - Milling cutters are used on CNC machines, precision engraving, and milling machines. When inserting the cutter into the collet, make sure it is properly inserted and clamped. Correct setting of the cutting speed and feed rate is very important for efficient and accurate cutting.</p>
