Specification Brand : HARFINGTON BulletPoint1 : Size - Shank Diameter: 3mm / 1/8"; Head Diameter: 6mm / 1/4"; Head Length: 13mm / 0.51"; Total Length: 50mm / 1.97"; Shape: 60 Degree Cone (M); Style: Single Cut BulletPoint2 : Material - 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. BulletPoint3 : Feature - Single cut burrs with single flute design provide a deeper, stronger cut, and produce larger chips and a rougher surface finish. Single burrs are often preferred when speed and efficiency are more required than a smooth finish. BulletPoint4 : Applications - The burrs are typically used in applications that require fast material removal and forming, and are suitable for machining harder materials such as ferrous metals, stainless steel, cast iron, alloy steel or hardened steel. Used for weld seam cleaning, and porting, removing excess material, or creating intricate details. BulletPoint5 : Note - Used with 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, keep the burrs sharp, and apply a coolant or lubricant.

Widely used in automotive, metal processing, woodworking, tool making and other industries. Single cut burrs with single flute design provide a deeper, stronger cut, and produce larger chips and a rougher surface finish. Single burrs are often preferred when speed and efficiency are more required than a smooth finish. The single cut carbide burrs are typically used in applications that require fast material removal and forming, and are suitable for machining harder materials such as ferrous metals, stainless steel, cast iron, alloy steel or hardened steel. 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.
