What it is

The Fervi ST2A28.25 taper shank twist drill bit is a drilling tool for metals with a 28.25 mm diameter, suitable for machines with a Morse taper shank. The 118° point angle ensures a balanced cut in steel, while the hardness of 700-740 HV gives the cutting edge wear resistance and consistency in repeated operations. The product is made to DIN 345/N.

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.
