The A125 drill from Dormer is classed as an extra long drill and is recommended for very deep holes and applications where the hole to be drilled is difficult to reach.
The A125 has a conventional 118 degree point, providing strength and saving money on easy regrinds.
A steam oxide finish helps stop work piece material from sticking to the cutting edge of the drill.
The A125 is manufactured from premium high speed steel and can be used in a variety of applications on a number of different materials, including steels, aluminium and stainless steels.
Please note – because of the extra length, we recommend the A125 is less suitable for hand-held drilling.
* Note: All drills below 2.2mm are bright
