Dormer P817 Bright 60° Countersink Carbide Burr

The Dormer P817 Bright 60° Countersink Carbide Burr with 9.6mm diameter cut offers excellent versatility for medium-sized chamfering and countersinking applications. With an 8mm cut length and 6mm shank diameter, this mid-range variant is perfectly suited for general workshop tasks, preparing bolt holes, and creating clean chamfers on pipework and fabricated assemblies.

The solid carbide cutting head maintains its sharpness through extended use on challenging materials including stainless steel, cast iron, and hardened components. The double cut flute geometry provides balanced performance between material removal speed and surface finish quality, making this an excellent all-round choice for both professional tradespeople and serious DIY enthusiasts.

At 56mm overall length with a robust 6mm shank, this burr offers good reach whilst remaining manageable for controlled, precise work. The bright finish ensures smooth operation and clear visibility, whilst the 60° angle creates industry-standard chamfers suitable for a wide range of engineering and fabrication applications.
