HSS PRO
HSS PRO is an industrial quality twist drill with outstanding performance and long service life. It is designed for drilling steel and steel castings, alloyed and non-alloyed
steel, cast iron, non-ferrous metals, plastics and other materials. The 118° split point shape provides an optimum centering when starting and a faster drilling rate. It
requires lower feed pressure than standard HSS drill bits with a chisel edge.
1.
118° SPLIT POINT SHAPE
With increased performance and very good centering
Precision starting, no need to pre-punch or pilot drill
Penetrates quickly
Requires less effort / feed pressure
2.
GREATEST TOUGHNESS
For low risk of breakage even when drilling with smaller
diameters due to high elasticity
3.
OPTIMUM DRILLING PERFORMANCE
Even in unfavourable working conditions
4.
HIGHLY ACCURATE
Close tolerances and high concentricity for maximum
precision
5.
HIGHEST STEEL GRADE
High-performance, High-Speed Steel
HSS PRO DRILL RANGE
The HSS PRO drill bits are available for a wide array of applications: DIN 338 jobber series, DIN 340 long series, double-ended stub series, DIN 345 Morse taper shank
series.

DIN 338 series is suitable for many trade and industrial applications in alloyed
and un-alloyed steel, non-ferrous metals, cast iron and plastics.
DIN 340
DIN 340 long series is most suitable for drilling deep holes or through hollow
profiles.
Double-Ended
Double-ended series is especially designed for drilling thin materials like
sheet metal, flat steel and profiles. Ideal for use with hand-held drills.
