About this product
The Dormer A125 is a high-speed steel extra-length drill bit designed for deep hole drilling and reaching awkward, hard-to-access areas. It is a general-purpose drill capable of drilling up to ten times its diameter, suited to professional and industrial use.
This bit has a standard spiral flute design with a 118° point angle and is steam tempered, manufactured to BS328. Diameter is 4mm, with a working length of 100mm and an overall length of 160mm.
Due to their extra length, care is needed to avoid bending or breaking during use — starting with shorter bits and letting the drilling machine do the work is recommended.
