10pcs 1/8" Shank 1.8mm Tungsten Carbide Blue Coated End Mill CNC Router Bits 9mm(ID)x11mm(OD)x300mm(L) Straight 3 flutes are groundMade of premium tungsten carbide, the router bits have excellent hardness, sufficient bending strength, wear resistance, durability, and good milling and cutting performance to ensure high working efficiency. Carbide ensures the bits can withstand the high speed and high stress requirements of CNC machining. The blue coating on end mills increases hardness, reduces friction and heat, improves lubricity, and protects bits from rust and corrosion.
