Fein 63111050010 Vario Impact Twist Drill Set (6.8mm, 8.5mm, 10.2mm, 12.0mm)

4-part VARIO twist drill set with 6.8 mm, 8.5 mm, 10.2 mm and 12 mm sizes.

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.
