Dormer P817 Bright 60° Countersink Carbide Burr

The Dormer P817 Bright 60° Countersink Carbide Burr with 6mm diameter cut is a popular mid-sized variant that balances precision and versatility for everyday countersinking tasks. With a 4mm cut length and 6mm shank diameter, this burr is ideal for preparing standard fastener holes, creating clean chamfers on brackets and plates, and general metalworking applications across both professional workshops and well-equipped home workshops.

The solid carbide construction ensures reliable performance across a wide material spectrum, from mild steel and cast iron to more challenging stainless steel and hardened components. The double cut flute geometry with closely spaced edges provides efficient cutting action whilst producing excellent surface finishes, making this an excellent choice for visible work where appearance matters.

At 50mm overall length, this compact yet capable burr offers good manoeuvrability without sacrificing stability. The 6mm shank diameter matches standard rotary tool collets, ensuring secure mounting and vibration-free operation. The bright uncoated finish provides smooth cutting action and allows operators to clearly monitor their progress during precision work.
