10Pcs 1/4" (6Mm) Head 1/8" (3Mm) Shank E-Shape Double Cut Carbide Rotary Burrs

Carbide rotary burrs, also known as carbide files or carbide grinding bits, are made of tungsten carbide, which has high hardness, excellent wear resistance, high temperature resistance, durability, and corrosion resistance. Widely used in automotive, metal processing, woodworking, tool making and other industries. Double cut burrs with cross-cut design can create small, uniform chips, provide efficient material removal, produce a smoother finish, and enables better control during machining. Double cut burrs are often preferred when precision and smoothness of the surface is required. The double cut carbide burrs are commonly used for general purpose applications, including deburring, shaping, polishing, engraving, and stock removal. Suitable for machining relatively low-density objects such as aluminum, metal, plastic, wood, and composite materials. Can be used for weld seam cleaning, porting and polishing, removing excess material, or creating intricate details. Used with handheld rotary tools such as die grinders, pneumatic air tools, or electric drills. Maximum speed is: 6000-50000 rpm/min. Always ensure the shank is well inserted into the collet and clamped tightly. Use the correct speed and pressure, and keep the burrs sharp. Using a coolant or lubricant reduces heat buildup, prevents excessive wear, maintains cutting efficiency and extends tool life. Clean the burrs and remove any debris or buildup after each use. Always wear appropriate personal protective equipment.
