Dormer P821 Bright Ball Nosed Cone Carbide Burr

The 8mm diameter Dormer P821 Bright Ball Nosed Cone Carbide Burr strikes an ideal balance between precision and material removal capacity. Featuring an 8mm diameter cut with a 25.4mm cut length, this variant is perfectly sized for medium-duty machining tasks including moderate hole enlargement, chamfering, deburring, and edge rounding on various metal components.

Manufactured from solid carbide with a bright finish, this burr delivers consistent performance across steel, cast steel, stainless steel, cast iron, copper alloys, high-temperature alloys, and hardened materials. The double cut geometry with closely spaced cutting edges ensures efficient material removal with a smooth finish, reducing the need for secondary finishing operations. With its 6mm shank diameter and 70mm overall length, this burr offers excellent reach and control for both professional engineering applications and home workshop metalworking projects.

Features and Benefits:
• Bright finish for controlled cutting action
• Solid carbide construction for extended tool life
• Ball nosed cone shape for versatile applications
• Double cut geometry for balanced cutting performance
