What it is

Black & Gold impact driver bits 1/4'' 10 x 137.5 x 99.5 DeWalt. Key specifications: connection 1/4'', length (mm) 137,5, diameter (mm) 10.

A metal drill bit is an HSS or cobalt twist drill, with a straight or taper shank, for drilling steel, non-ferrous metals and plastics.

What it is for

Used for drilling steel, stainless steel and aluminium, on a pillar drill or with a hand-held drill and in workshop machining of steel, aluminium and alloy parts.

How to use it

Clamp the workpiece in a vice, mark the centre and set the speed for the diameter and material: low for hard steels and large diameters, higher for aluminium and plastic. Lubricate with cutting oil on steel; on plastic, reduce the pressure as the bit breaks through to avoid chipping. Insert taper-shank drills into the pillar drill's spindle taper and remove them with a drift.
