MINI TUNGSTEN CARB. CUTTER 3.2MM ROUND POINT 3.2MM SHANK

Tip Diameter: Ø3.2mm
Shank Diameter: Ø3.2mm
Shape: Round Point

Achieve unparalleled precision in your detailing work with the 3.2mm Mini Tungsten Carbide Round Point Cutter. This versatile bit features a unique round point shape, also known as a ball-nose or radius-end cylinder, which combines the straight-edge cutting power of a cylinder with a smooth, curved tip. This geometry is specifically engineered for carving U-shaped grooves, rounding off sharp internal corners, and performing intricate 3D contouring where a flat-bottomed tool would be too aggressive.

Designed for seamless operation, the 3.2mm tip diameter is perfectly aligned with the 3.2mm shank, providing a slim and balanced profile. This 1:1 ratio ensures excellent tool-to-workpiece visibility and fits effortlessly into standard rotary tools and high-speed handpieces. The precision-ground shank minimizes runout, allowing for smooth, chatter-free material removal even at the high speeds required for professional-grade engraving and finishing.

Forged from industrial-grade tungsten carbide, this cutter is built to outlast traditional steel bits by a significant margin. Its incredible hardness allows it to bite into the toughest materials—including stainless steel, cast iron, hardwoods, and reinforced plastics—while maintaining a sharp edge under extreme heat. The specialized flute geometry is designed to clear debris rapidly, ensuring that the tool remains cool and efficient during prolonged carving or deburring sessions.

This round point carbide burr is a favorite among mold makers, custom jewelers, and automotive enthusiasts for its ability to create fluid transitions and organic shapes. Whether you are porting an engine intake, hollowing out a delicate wood carving, or refining a metal sculpture, this tool provides the perfect blend of aggressive cutting power and refined finishing capability for any high-stakes project.
