Long cylindrical twist drill bit Fervi P023/08.50L

What it is

Made to DIN 340, the Fervi P023/08.50L long straight-shank twist drill bit has a diameter of Ø 8.5 mm and a point angle of 135°. The standardised long version offers a greater working stroke, suited to deep holes, while the blunt-point grind ensures stable, smooth centring. The HV 770-830 hardness ensures good wear resistance when drilling metal.

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.
