Dormer P807 Bright Ball Carbide Burr

The Dormer P807 Bright Ball Carbide Burr with 4mm diameter cut is a fine precision tool designed for detailed metalworking where accuracy and control are paramount. This compact variant excels in intricate carving, detailed engraving, small-radius weld preparation, and precision surface refinement tasks. The 3mm shank diameter provides excellent compatibility with precision rotary tools and smaller die grinders.

With a 3.4mm cut length and 38mm overall length, this burr offers exceptional manoeuvrability for creating fine contours and detailed profiles in steel, stainless steel, cast iron, and hardened materials. The solid carbide construction maintains sharp cutting edges even when working with demanding materials, whilst the double cut geometry delivers controlled material removal with minimal vibration. Ideal for mould making, jewellery work, precision engineering, and detailed fabrication where fine control and accuracy are essential for both professional craftspeople and dedicated hobbyists.
