## Description

### What it is

The Fervi ST2A25.50 is a taper-shank twist drill bit for professional metal drilling, with a diameter of Ø 25.50 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.

### Where it is used

- Mechanical engineering industry
- Mechanical workshops

### Who it is for
