About this product
The Dormer A125 is a high-speed steel extra-length drill bit, designed for deep hole drilling and long-reach applications in professional and industrial settings. It is a general-purpose drill capable of drilling up to ten times its diameter, made to BS328 with a standard spiral flute design, 118° point angle, and steam tempering for durability.
This version has a 10mm tip diameter, a 250mm working length and an overall length of 315mm. Care should be taken when using extra-long bits to avoid bending or breaking, starting with shorter bits where possible and allowing the drilling machine to do the work rather than applying excessive pressure.
