Dormer P101 150 Deg Countersink Carbide Burr

The Dormer P101 150° Countersink Carbide Burr with 7.8mm diameter cut is perfectly suited for M8 bolt removal applications, making it an invaluable tool for automotive mechanics, agricultural machinery repairs, and general fabrication work. This mid-range variant strikes an excellent balance between precision and capacity, handling a wide variety of broken bolt scenarios encountered in both professional workshops and home engineering projects.

Featuring a 150° angle and single-cut flute style, this burr creates accurate countersink locations on flattened broken bolt surfaces with the 5mm cut length providing controlled cutting depth. The solid carbide construction with medium-spaced edges ensures efficient material removal on steel, cast steel, and stainless steels, including ferritic, martensitic, and austenitic grades, delivering reliable performance across diverse 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 without damaging threaded holes
• Creates a precise centrepoint into the flattened broken bolt for accurate drilling
• Micrograin carbide provides extreme hardness and wear resistance for prolonged tool life
