Dormer P809 Solid Carbide Oval Rotary Burr 3mm x 38mm

The Dormer P809 solid carbide oval rotary burr features oval ball nose geometry with skip flute grinding to increase strength at the centre and reduce swarf congestion. Its double-cut tooth pattern offers efficient metal removal and improved control while breaking swarf into manageable pieces. Toughened, hardened steel shanks provide rigidity to resist bending and reduce vibration, and precision grinding to h6 (carbide) and h7 (steel) ensures consistent fit and balance. Special brazing elements deliver excellent braze strength for reliable performance. Specifications: diameter 3 mm, shank 3 mm, working length 6 mm, overall length 38 mm.

Oval ball nose geometry with skip-flute grinding increases centre strength and durability.

Skip-flute pattern reduces swarf congestion and improves cutting action closer to the centre.

Double-cut tooth pattern provides fast, controlled material removal for general machining tasks.

Improved ease of control and higher metal removal rate while breaking swarf into manageable pieces.

Toughened, hardened steel shanks deliver rigidity and resistance to bending under load.

Reduced vibration from rigid shanks extends tool life and improves surface finish.

Precision ground to h6 (carbide) and h7 (steel) tolerances for consistent fit and balance.
