Dormer P813 Solid Carbide Rotary Burr Pointed Tree 6.3mm x 3mm Shank

The Dormer P813 solid carbide rotary burr features a pointed tree (ball-nose) geometry with skip-flute grinding to increase centre strength and reduce swarf congestion. Its double-cut pattern delivers smooth, controllable machining, improved metal removal rates and consistent chip breaking. The burr uses a toughened, hardened steel shank to resist bending and reduce vibration, and is precision-ground to h6 (carbide) and h7 (steel) tolerances for reliable fit. Special brazing elements and excellent impact strength improve heat resistance and durability. Dimensions: head diameter 6.3 mm, shank diameter 3 mm, working length 12.7 mm, overall length 45 mm.

Pointed tree ball-nose geometry with skip-flute grinding for increased centre strength and reach.

Reduced swarf congestion and improved cutting action closer to the centre for consistent results.

Double-cut pattern ideal for general machining and smooth material removal.

Breaks swarf into manageable pieces while increasing metal removal rate for faster work.

Toughened, hardened steel shank provides rigidity and strength under load.

Reduced bending and vibration improve operator control and extend tool life.

Precision ground to h6 (carbide) and h7 (steel) tolerances for reliable fit and performance.
