Dormer P817 Bright 60° Countersink Carbide Burr

The Dormer P817 Bright 60° Countersink Carbide Burr with 3mm diameter cut is the smallest variant in the range, making it ideal for precision work on delicate components and intricate detail work. With its compact 2.5mm cut length and 3mm shank diameter, this burr is perfect for fine chamfering operations, creating small V-cuts, and detailed welding preparation where accuracy and control are paramount.

Constructed from solid carbide with a toughened, hardened steel shank, this burr maintains its cutting edge even when working with hardened materials, stainless steel, and high-temperature alloys. The double cut flute geometry ensures efficient chip evacuation whilst delivering excellent surface finishes on both ferrous and non-ferrous metals.

At just 38mm overall length, this compact burr offers exceptional manoeuvrability in tight spaces and confined areas, making it particularly valuable for precision engineering, instrument making, and detailed fabrication work where larger tools cannot reach.

Features and Benefits:
• Compact 3mm diameter for precision detail work
• Solid carbide construction for extended tool life
• Double cut geometry for superior finish quality
• Bright finish for smooth operation
