RUKO FRS-D-3.0mm Ball/Cross-Cut Carbide Burr

Carbide burr with spherical head shape and cross-cut tooth pattern, ideal for precise deburring, chamfering, and contouring in hard-to-reach areas. The 3.0 mm ball-shaped head and cross-cut design provide excellent control and a smooth finish on a variety of metals.

Advantages

Cross-cut tooth geometry reduces vibration and improves chip breaking, resulting in cleaner surfaces and longer tool life. Tungsten carbide construction ensures high hardness and wear resistance, suitable for high-speed operation up to 250,000 RPM.

Suitable for

• Deburring and edge breaking on steel, cast steel, and stainless steel (INOX)
• Milling and contouring of non-ferrous metals and cast iron
• Precision work in die grinding, straight grinding, and flexible shaft machines
