Fein 63111050010 VARIO Impact Twist Drill Set (6.8/8.5/10.2/12mm)
The FEIN VARIO Impact Twist Drill Set is a professional-grade drilling accessory set engineered specifically for impact wrench and impact driver applications. Designed for high-speed impact drilling, this VARIO drill set delivers precise hole preparation for threading applications while ensuring long service life and dependable performance in demanding industrial, fabrication and metalworking environments.
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.
Each drill bit is coated with TiAlN (titanium aluminium nitride), which reduces friction, minimises wear and provides heat resistance up to 800°C. This ensures extended service life and consistent drilling performance even in tough materials such as non-alloyed and alloyed steels up to 900 N/mm², as well as aluminium and brass. The VARIO bit shaft interface guarantees secure tool engagement and efficient torque transfer during repetitive professional use.
