Dormer P101 150 Deg Countersink Carbide Burr

The Dormer P101 150° Countersink Carbide Burr with 9.3mm diameter cut is optimised for M9 and similar-sized bolt removal tasks, making it particularly useful for machinery maintenance, plant equipment repairs, and industrial applications. This variant offers excellent coverage for mid-to-large fastener removal, providing the precision needed for critical engineering tasks in both professional workshops and well-equipped home workshops.

The 150° angle and single-cut flute style ensure accurate countersink locations on flattened broken bolt surfaces, whilst the 5mm cut length delivers controlled depth for precise centre marking. With solid carbide construction and medium-spaced edges, this burr delivers efficient cutting performance on steel, cast steel, and stainless steels, including ferritic, martensitic, and austenitic grades, making it versatile for demanding extraction 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 and protect threaded components
• Creates a precise centrepoint into the flattened broken bolt for accurate extraction drilling
• Micrograin carbide provides extreme hardness and wear resistance for maximum tool longevity
