Dormer A1254.5X315 HSS Extra Length Drill Bit, 4.5mm x 315mm (250mm working length)

Dormer A1254.5X315 is an HSS extra length drill bit designed to help you drill deeper holes in metal when standard-length bits don’t offer enough reach. With a 4.5mm cutting diameter and extended working length, it’s a practical choice for workshop and site tasks where access is restricted or the drilling depth is increased.

This Dormer A125 metal drill bit is supplied as a single bit and suits users who want a longer-reach twist drill for controlled drilling in metalwork and fabrication.
