What it is
The Fervi ST2A77 taper shank twist drill bit is a cutting tool intended for drilling metals on machines fitted with a taper shank. Built to DIN 345, it has a 118° point angle, a classic geometry that ensures gradual penetration and good chip flow. The hardness of HV 700-740 gives the cutting edge wear resistance and operating stability, even in the most continuous operations.
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.
