What are the dimensions of this burr?

The burr has a head diameter of 8 mm, a cut length of 20 mm, and a cylindrical shank of 6 mm.

Which materials is cut Z3 suitable for?

Cut Z3 with chip breaker is ideal for machining steel, cast steel, and cast iron.

What is the benefit of the end cut (shape A-ST)?

The end cut allows you to cut material using both the outer circumference and the front end face.

What is the recommended rotational speed for this burr?

For steel and cast iron, the recommended operating speed is between 3200 and 4000 RPM.

Why choose an HSS burr over a carbide burr?

High-speed steel (HSS) offers high toughness, impact resistance, and cost efficiency on lower-RPM drives.

Versatile and efficient milling with Pferd

Practical benefits

Efficient machining with end cut: With its front-end cut and integrated chip breaker, you easily tackle inner contours, blind holes, and deburring tasks on steel or cast materials.
Stable at low speeds: The tough HSS construction lets you work aggressively at lower rotational speeds while maintaining smooth operation without chatter marks.
Precise 6MM cylindrical shank: The balanced 6MM shank fits securely into your standard drive tools, ensuring true concentricity and reduced drive wear.

In a nutshell

The right choise for

With the Pferd hss a 0820ST/6 Z3 hss burr, you machine and deburr steel, cast steel, and cast iron with total control. The integrated end-cut teeth (shape A-ST) and chip breaker enable simultaneous face and peripheral milling, making it easy to rework inner contours, slots, and blind holes. Thanks to its tough high-speed steel construction, the burr performs reliably at lower rotational speeds between 3200 and 4000 RPM, delivering smooth, chatter-free stock removal on straight die grinders. Featuring an 8 mm head diameter, a 20 mm cut length, and a balanced 6 mm cylindrical shank, this tool provides secure concentricity and a clean, medium-fine surface finish.

Product description

PFERD HSS rotary cutter cylindrical shape end A-ST dia. 08x20mm shank dia. 6mm 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
Cylindrical burr with end cut

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.
