Dormer A1258.0X315 HSS Extra Length Metal Drill Bit, 8.0mm x 315mm

Dormer A1258.0X315 is an HSS extra length drill bit designed for deep-hole drilling in metal, giving you the reach needed when standard jobber drills are too short. With an 8.0mm cutting diameter and extended flute length, it’s a practical choice for fabrication, maintenance and workshop drilling tasks where controlled depth and access matter.

This A125 series metal drill bit features a straight shank for use in suitable drill chucks, and is made for trade users who want a longer-reach solution without compromising on everyday usability.
