Dormer P101 150 Deg Countersink Carbide Burr

The Dormer P101 150° Countersink Carbide Burr is expertly designed for precision countersinking tasks, delivering exceptional performance and reliability in challenging materials. This specialist bolt removal burr features a solid carbide construction and a durable toughened steel shank, ensuring longevity and consistent results in demanding applications whether you're working in a professional workshop or tackling DIY repairs at home.

With its 150° angle and single-cut flute style, it is optimised for creating accurate countersink locations on flattened surfaces, such as broken bolts, providing smooth finishes and precise results. The medium-spaced edges enhance cutting efficiency, making it ideal for use on steel, cast steel, and stainless steels, including ferritic, martensitic, and austenitic grades. Available in sizes from 4.9mm to 10.7mm diameter cut, this range covers most common bolt removal applications.

Features and Benefits:
• Ground finish prevents work material from sticking to the cutting edges
• Part of a specialist range designed to prepare broken bolt surfaces to improve drill location and prevent damaging threaded holes
• Creates a precise centrepoint into the flattened broken bolt for accurate drilling
• Micrograin carbide provides extreme hardness and wear resistance for increased tool life when machining difficult materials
