RUKO FRS-A-3.0mm Cylindrical Cross-Cut Tungsten Carbide Rotary Burr

The RUKO FRS-A-3.0mm cylindrical cross-cut burr is a precision tool for deburring, edge breaking, and surface finishing on hard materials. Its cross-cut tooth geometry reduces chatter and leaves a smoother finish than single-cut burrs, making it suitable for work on steel, stainless steel, and cast iron. The 3.0 mm head diameter and 38 mm overall length allow access to tight contours and small bores.

Highlights

• Cylindrical (Form A) shape with cross-cut (Z3) teeth for controlled stock removal
• Solid tungsten carbide head for high wear resistance and long tool life
• 3.0 mm shank diameter fits standard die grinders and rotary tools
• Recommended for steel, stainless steel (INOX), cast iron, non-ferrous metals, and plastics

In daily use

Mount the burr in a die grinder or flexible shaft machine and run at speeds up to 80,000 RPM. The cross-cut pattern produces small chips and reduces vibration, improving control when working on edges, weld seams, or mold surfaces. The cylindrical profile is ideal for flat surfaces, slots, and internal corners.
