Dormer P101 150 Deg Countersink Carbide Burr

The Dormer P101 150° Countersink Carbide Burr with 6.4mm diameter cut is perfectly sized for common M6 bolt removal tasks, making it an essential tool for automotive repairs, machinery maintenance, and general engineering applications. This variant features a solid carbide construction with a 6mm shank diameter, ensuring compatibility with standard drill chucks and rotary tools used in both professional workshops and home garages.

The 150° angle and single-cut flute style create accurate countersink locations on flattened broken bolt surfaces, whilst the 5mm cut length provides controlled cutting depth. The medium-spaced edges deliver efficient material removal on steel, cast steel, and stainless steels, including ferritic, martensitic, and austenitic grades, making it versatile for a wide range of bolt extraction projects.

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 threaded hole damage
• Creates a precise centrepoint into the flattened broken bolt for accurate drilling
• Micrograin carbide provides extreme hardness and wear resistance for extended tool life
