Pferd rotary burr for precise metalworking

Practical benefits

Efficient material stock removal: The integrated chip breaker geometry delivers steady material removal while preventing chatter marks on steel and cast iron components.
Effortless access to contours: The flame profile lets you navigate curved inner surfaces, narrow cavities, and complex workpiece shapes with great precision.
Dependable at lower speeds: Tough high-speed steel construction resists edge chipping and delivers reliable cutting performance on drive units with lower rotational speeds.

In a nutshell

The right choise for

With the Pferd hss b 0820/6 Z3 hss rotary burr, you can effortlessly machine hard-to-reach cavities, inner radii, and complex contours. The slender flame shape, featuring an 8 mm diameter and a 20 mm cut length, gives you complete control when deburring, shaping, or dressing weld seams. Thanks to the tough hss build and cut Z3 geometry with an integrated chip breaker, you achieve steady material removal on steel and cast iron without disruptive chatter. Engineered for drive units running at lower rotational speeds, it mounts smoothly into straight grinders, flexible shafts, or drills with a 6 mm collet to keep your metalworking precise and efficient.

Product description

PFERD HSS rotary cutter flame-shaped B dia. 08x20 mm shank dia. 6 mm Z 3 universal medium fine chip breaker

Characteristics

Cut 3 has chip breakers and is especially well-suited to machining of steel, cast steel and cast iron
It is used in a rotational speed range of 1,200 to 7,900 RPM, depending on the burr diameter
Flame-shaped burr

Advantages:

Highly aggressive.
Can be used at low rotational speeds.
Very robust tooth cutting edges due to the toughness of the high-speed steel (HSS).
The highly accurate concentricity enables impactfree working without creating chatter marks. This considerably reduces wear on the tool and tool drive.
