Pferd 21202553 Flame Shape Burr B, Cut 5, 3 x 7 mm, 3 mm Shank

This Pferd flame shape burr (B) is a tungsten carbide burr in cut 5 on a 3 mm shank (manufacturer-stated). This page lists 2 items, head sizes 3 x 7 and 6 x 13 mm (manufacturer-stated).

The PFERD catalogue describes cut 5 as the fine-machining cut for steel, cast iron, stainless steel (INOX) and high-temperature-resistant materials such as nickel-based and cobalt-based alloys, giving a good surface (manufacturer-stated).

The PFERD catalogue describes the B as a flame-shaped burr according to ISO 7755/8, with a cut conforming to DIN 8033, for general use on all materials (manufacturer-stated).

Features listed: long tool life and high surface finish; reduced wear on the tool drive from impact-free work without chatter marks, thanks to the high concentricity (manufacturer-stated).

Common specifications

Key specifications

Dimensions in mm: d1 head diameter, l2 cut length, d2 shank diameter, l1 overall length. Each item number is one head size.

Selecting the right option

Choose the head size and shank to suit the job and your tool; the table lists each item number with its dimensions. The catalogue gives a cutting speed of 450 to 600 m/min for fine stock removal on steels up to 1,200 N/mm2, and the rotational speed follows from the burr diameter (manufacturer-stated). Do not exceed the maximum permitted rotational speed, observe the recommended rotational speed (especially with long shanks), wear eye and hearing protection and a dust mask, and do not use a damaged burr or use the burr for cutting (manufacturer-stated).
