Cylindrical twist drill bit Fervi ST1A07.75
Also known as: metal drill bit
Key features
- Diameter (mm)7,75
- Point angle118°
- Hardness700-740 HV
- StandardDIN 338
What it is
With a diameter of Ø 7.75 mm, the Fervi ST1A07.75 is a twist drill bit designed for professional drilling that requires sizes outside the standard values. The flute ensures orderly chip flow, helping to keep hole quality consistent, while the 118° point angle ensures stability during centring. The 700-740 HV hardness offers adequate edge retention even in repeated use.
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.
