Dormer P101 150 Deg Countersink Carbide Burr

The Dormer P101 150° Countersink Carbide Burr with 4.9mm diameter cut and 20mm cut length is specifically sized for smaller bolt removal applications, making it ideal for working with compact fasteners and precision engineering tasks. This variant combines a solid carbide construction with a durable toughened steel shank, ensuring exceptional performance when dealing with broken bolts in tight spaces or delicate components.

The 150° angle and single-cut flute style create accurate countersink locations on flattened surfaces, whilst the extended 20mm cut length provides greater working depth compared to other variants in the range. The medium-spaced edges enhance cutting efficiency on steel, cast steel, and stainless steels, including ferritic, martensitic, and austenitic grades, making it versatile for both professional engineering and home workshop 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
• Creates a precise centrepoint into the flattened broken bolt
• Micrograin carbide provides extreme hardness and wear resistance for increased tool life
