RUKO FRS-D-6.0mm Ball Nose Double Cut Rotary Burr, 3mm Shank, HSS

Deburring, chamfering, and weld preparation in hard-to-reach contours demand a rotary burr that combines precise geometry with durable cutting edges. The RUKO FRS-D-6.0mm ball nose double cut rotary burr addresses these tasks with a 6 mm ball-shaped head and double cut tooth pattern for controlled stock removal and a smooth finish on steel, cast steel, stainless steel, non-ferrous metals, and cast iron.

Who is it for

Machinists, metal fabricators, and maintenance technicians who use die grinders, straight grinders, or flexible shaft machines for manual or CNC-assisted deburring and surface work. The ball nose profile suits concave radii, rounded grooves, and edge breaking where a cylindrical or conical burr cannot reach.

Main features

• Ball-shaped head (Form D) with 6.0 mm diameter and 5.0 mm head length for contour work.
• Double cut (Kreuzverzahnt / Z3 PLUS) tooth geometry for reduced chatter and finer finish compared to single cut.
• High-speed steel (HSS) body, milled and bright finished, for general-purpose use on ferrous and non-ferrous metals.
• 3.0 mm shank diameter and 45 mm overall length fit standard collets and chucks.
• Maximum permissible rotational speed: 38,000 RPM.
• Complies with DIN 8032 dimensional standard.

Tips

Use light, steady pressure and let the tool do the work; excessive force shortens burr life and degrades finish. For stainless steel, keep cutting speed below the maximum and use a suitable cutting fluid to prevent work hardening. Clean the burr after use to remove chips and extend service life.
