5 parts, 1 each of M8 x 1.25 mm, M10 x 1.5 mm, M12 x 1.75 mm, M14 x 2.0 mm, M16 x 2.0 mm in cylindrical packaging. Long service life, thanks to high material strength (64 HRC), special cutting geometries suited to impact wrench/drivers and a TiAlN (titanium-aluminium-nitride) coating. The bits experience low levels of wear and friction as well as being heat-resistant to 800 °C. Thanks to the high speeds and number of blows, they can therefore be used in steel up to 900 N/mm².|Perfectly suited to the following materials: non-alloyed and alloyed steels up to 900 N/mm², aluminium, brass.
