sourcing map 4mm End Mill Bits 1/6"(4mm) Straight Shank Solid Carbide CNC Router Bits Engraving Cutter Tool with Corn Blade for PCB Circuit Board Milling Machine Wood Carving

Product description

• Size - Cutting edge diameter 4mm 0.16"; shank diameter 4mm 1 6"; cutting edge length 20.0mm 0.79"; overall length 50mm 1.97"; left right rotation right rotation; blade shape fishtail corn shape; shank form straight shank; style with positioning ring; package included 1pc carbide end Mill.
• Material - This milling cutter is made of tungsten steel (carbide), which has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. These properties extend tool life and keep end mills sharp, helping to improve cutting accuracy and efficiency.
• Feature - Corn-shaped cutting edge, diamond-shaped cutting teeth, fishtail-shaped cutting tip, CNC router bits integrating drilling and milling. This manufacturing process effectively reduces cutting resistance, minimizes vibration during processing and reducing errors caused by tool vibrations, ensuring a smoother cutting process without damage.
• Application - This flat end mill is frequently used in PCB circuit boards, various CNC milling machines, woodworking CNC tools, and engraving machine tools. In addition, it is also suitable for cast iron, copper, carbon steel, alloy steel, pre-hardened steel, and hardened steel processing of metal materials.
• Note - Most end mills are clamped using spring clamps, to prevent the end mill from gradually protruding from the tool holder or even falling completely, we recommend that the end mill handle and tool holder be removed before clamping the end mill, clean the inner hole with cleaning fluid and dry it before clamping.
