What it is
The Fervi ST2A27.50 is a taper-shank twist drill bit for professional metal drilling, with a diameter of Ø 27.50 mm. The cutting edge with a 118° point angle ensures steady penetration into steel, while a hardness of HV 700-740 ensures a durable, stable edge even in demanding operations. Construction complies with DIN 345, the established standard for this type of drill bit.
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.
