Dormer A125 HSS Extra Length Drill 10.00mm x 250mm OL:250mm WL:200mm | A12510.0X250

Dormer A12510.0X250 HSS Extra Length Drill Bit, 10.0mm x 250mm

Dormer A12510.0X250 is an HSS extra length drill bit designed for long-reach and deep-hole drilling where a standard-length bit cannot access the work area. With a 10.0mm cutting diameter and extended flute length, it suits workshop and on-site metalworking tasks that need added reach while maintaining reliable hole size and control.

This Dormer A125 series drill is a practical choice for general drilling applications across common engineering materials, with an extra-long pattern that helps when working through thicker sections or drilling deeper holes with controlled chip evacuation.

Key Features

• Extra length pattern: Provides increased reach for deep holes and access in restricted positions compared with standard-length drill bits.
