Dormer P101 150 Deg Countersink Carbide Burr

The Dormer P101 150° Countersink Carbide Burr with 10.7mm diameter cut is the largest variant in the range, specifically designed for M10 and larger bolt removal applications. This size makes it ideal for heavy-duty engineering, structural steel work, and industrial maintenance where larger fasteners have failed or sheared. The solid carbide construction ensures it can handle the demanding conditions encountered when working with substantial broken bolts.

With its 150° angle and single-cut flute style, this burr creates accurate countersink locations on flattened surfaces, whilst the 5mm cut length provides controlled precision. The medium-spaced edges deliver efficient cutting performance on steel, cast steel, and stainless steels, including ferritic, martensitic, and austenitic grades, making it suitable for both professional engineering workshops and serious DIY applications involving heavy machinery repairs.

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 prevent component damage
• Creates a precise centrepoint into the flattened broken bolt for accurate extraction
• Micrograin carbide provides extreme hardness and wear resistance for maximum tool life
