Pferd 21725212 Conical Pointed Burr SKM, Cut 3 PLUS, 6.35 x 19 mm (1/4 x 3/4 in)

This Pferd conical pointed burr (SKM) is a tungsten carbide burr in cut 3 PLUS on a 6.35 mm shank (manufacturer-stated). This page lists 3 items, head sizes 6.35 x 19 to 12.7 x 25.4 mm (manufacturer-stated).

The PFERD catalogue describes cut 3 PLUS as similar to cut 3 but with a cross cut, for machining steel, cast iron, stainless steel (INOX), nickel-based alloys and titanium alloys, with high stock removal and good surfaces (manufacturer-stated).

The PFERD catalogue describes the SKM as a conical pointed burr with flattened tip according to DIN 8032, 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 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).
