Dormer High Speed Steel Extra Length Drill Bit 10.5 mm Shank, Overall Length 315 mm, 10 Flutes A12510.5X315

Dormer A12510.5X315 is a high speed steel extra length drill bit with a 10.5 mm shank diameter and an overall length of 315 mm. It is specially designed for demanding machining and drilling applications requiring long reach and depth.

Manufactured using high speed steel, this drill bit offers excellent wear resistance and durability, suitable for general machining tasks involving steel and cast iron. The 10 helical flutes aid in chip evacuation to prevent fouling during drilling of deep holes up to 10 times the drill diameter.

The drill features a cylindrical/straight bright finish shank for reliable chuck grip, a right-hand cutting direction, and a standard 118° drill point angle optimized for efficient penetration and minimal walking. The steam tempered finish further enhances the tool life by improving wear resistance.

This high quality drill meets BS 328, DIN340 RN, and ISO standards, ensuring precision and performance consistency. It is often used in industrial, mechanical, and manufacturing settings for producing accurate holes with sizes of 10.5 mm diameter and drilling depths up to 250 mm.

Its extra length characteristics make it ideal for applications involving deeper hole drilling and interrupted drilling (pecking) processes, commonly encountered in fluid power, mechanical, and industrial tooling sectors.

Constructed from high speed steel for enhanced durability and wear resistance. Features 10 helical flutes enabling efficient chip removal during drilling. Cylindrical/straight bright finish shank designed for secure holding in drill chucks.
