High material removal with Pferd

Practical benefits

Extreme resistance to impact: The robust tooth geometry prevents chipping and breakage, allowing you to tackle demanding steelwork with confidence.
Smooth and chatter-free operation: Precise concentricity ensures vibration-free milling without chatter marks, significantly reducing wear on your power tool.
Versatile rounded tree shape: The curved profile allows you to effortlessly dress welds and contour inner radiuses with high precision.

In a nutshell

The right choise for

With the Pferd rbf 0820/6 tough carbide burr, you achieve reliable stock removal under heavy impact loads and tough working conditions. The robust tough cut prevents tooth breakage and chipping when machining steel, cast steel, and cast iron up to 54 HRC. Thanks to the rounded tree shape with an 8 mm head diameter and a 20 mm cutting length, you can easily deburr weld seams and contour inner radiuses. Its 6 mm cylindrical shank provides smooth, chatter-free operation on straight die grinders and flexible shaft drives, even at lower speed ranges, giving you maximum control.

Product description

PFERD Tungsten carbide high-performance burr TOUGH tree shape with radius end RBF dia. 08x20 mm shank dia. 6 mm impact-resistant

Characteristics

The TOUGH cut has been developed especially for tough applications in dockyards, foundries and steel construction
It is also ideal for use in all manufacturing sectors where, due to the difficult production environment, tooth breakages or other damage to conventional burrs is a frequent occurrence
Tungsten carbide burrs with the TOUGH cut are particularly aggressive and are characterized by high stock removal
Tree-shaped burr with radius end according to DIN 8032

Advantages:

The highly accurate concentricity enables impactfree working without creating chatter marks. This considerably reduces wear on the tool and tool drive.
The innovative quick-mounting system ensures convenient handling and cool grinding.
Minimized tooth chipping/breakage, splintering and burr failures due to very robust, high-performance cuts.
Can also be used in low rotational speed ranges.
Due to their extreme impact resistance, they are ideal for use as long-shank variants.
