1.) Preserves the tool
The extra deep bit fit ensures a safe hold of the screwdriver in cross recess PZ- and star socket TX drives. The Bit does not turn through anymore.
2.) Clean results
Easy countersink and an ideal surface finish.
3.) Protection against turning
As a strengthened transition from the screw shank to the screw head, the double cone protects the screw from turning - especially for fixings in hard wood or steel parts.
4.) Force- and battery conservation
The shank ribs decrease the screw-in resistance significantly.
5.) Preserves the wood
The front double thread reduces the cleavage of the wood.
At the same time, the middle double thread provides an unchecked propulsion of the screw.
6.) Extremely fast
Cutting notches and the Power-Fast high performance sliding coating reduce the friction effectively.
7.) Extremely fast bite
The thread up to the tip guarantees a fast bite.
