The Dormer A51012.0 tin-coated HSS jobber drill bit has a 12 mm diameter, a flute length of 101 mm, and an overall length of 151 mm. Constructed from high-speed steel with a tin coating, it is designed for metal drilling and provides wear resistance typical of tin-coated HSS bits. As a general-purpose jobber-length drill bit, it is suitable for common metalworking tasks where a standard-length bit is needed, including drilling through steel and other alloys.
