HARFINGTON 10pcs End Mills CNC Router Bits 1/8" Shank 3.175mm Blue Coated Tungsten Carbide Milling Cutters for PCB Acrylic Wood Aluminum Metal - hta230723hh000179

• Size - Cutting edge diameter: 3.175mm / 0.125". shank diameter: 3.175mm / 1/8". cutting edge length: 13mm / 1/2". overall length: 38mm / 1-1/2" Material - Made of premium tungsten carbide, the cnc router bits have excellent hardness, sufficient bending strength, wear resistance, durability, and good milling and cutting performance to ensure high working efficiency. Features - The blue coating increases hardness, reduces friction and heat, improves lubricity, and protects bits from rust and corrosion. Provides longer tool life, higher wear resistance, smoother chip evacuation. The surface is quite clean, neat, and no glitches. Applications - Suitable for PCB, plastic, wood, aluminum, copper, stainless steel. Great for precision milling, profiling, grooving, engraving and other CNC machining operations. The sharp cutting edges ensure clean cuts, precise dimensions, and minimal vibration. Note - The end mills are used on CNC machines, precision engraving and milling machines. When inserting the router bit into the collet, make sure it is securely seated and tightened. Correct adjustment of cutting speed and feed rate is very important for efficient and accurate cutting.
