Twist drill bits
Bits made of cobalt super-fast steel
Designed for cutting all metals,
from the softest to the hardest, these bits are made from high content cobalt
high speed steel (8%) and they are entirely ground. The diamond sharpening with
a 130° angle allows higher cut and feed speeds than the normal ground bits in
high speed steel when cutting normal building steel, and drilling high alloy
and stainless steels. The generated temperatures do not damage the cutting edge
of these bits since the cobalt properties increase the steel’s resistance to
heat. Owing to the hardness of these bits, care must be taken in the use of the
small sizes with hand drill machines since too many deflections could result in
breakage.
Ground high speed steel bits
Completely manufactured from a
heat treated steel bar, they are recommended for a professional and industrial
use for drilling steel up to 900-100 N/mm
2
and light alloys. The
high performance in chip removal and drilling accuracy are guaranteed by the
advanced production process offering perfect geometry, flat flutes and perfect
sharpened cutting edges.
Rolled high speed steel bits
The heat production process
produces drill bits of very good quality for light duty drilling metals at low
cost, such as iron, mild steel, light alloys and non ferrous metals.
