What it is
The Fervi ST2A31.50 taper shank twist drill bit is designed to produce large-diameter holes in metal with precision and reliability. The 31.50 mm diameter and the 118° point angle promote stable, well-centred drilling, while the hardness of 700-740 HV ensures cutting-edge wear resistance. The workmanship complies with DIN 345/N, the reference standard for taper shank drill bits.
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.
