Dormer P817 Bright 60° Countersink Carbide Burr

The Dormer P817 Bright 60° Countersink Carbide Burr with 12.7mm diameter cut is the largest variant in the range, designed for substantial chamfering operations and larger V-cuts. Featuring an 11mm cut length and 6mm shank diameter, this burr is ideal for general fabrication work, structural metalworking, and preparing larger diameter fastener holes.

The solid carbide construction ensures this burr can tackle demanding materials including cast iron, hardened steel, and high-temperature alloys without losing its cutting edge. The double cut flute design with closely spaced edges delivers efficient material removal whilst maintaining excellent surface quality, reducing the need for secondary finishing operations.

With a 59mm overall length and robust 6mm shank, this burr provides the reach and stability needed for larger workpieces and production environments. The bright uncoated finish allows operators to clearly see their work whilst the 60° angle creates perfect chamfers for both functional and aesthetic applications.

Features and Benefits:
• Large 12.7mm diameter for substantial chamfering operations
• Solid carbide construction for durability on demanding materials
• Double cut geometry for efficient material removal
• 6mm shank for secure mounting in professional rotary tools
