The Wera 848/851/867/19 metal spiral drill bits and bit set includes a Rapidaptor bit holder with a quick-change chuck, twelve tough bits, and six HSS metal spiral drill bits with a 1/4" drive. The extra tough bits are characterized by an exceptionally long lifespan, preventing premature breakage. The Phillips bits are tough bits with a torsion zone that absorbs torque peaks, thereby avoiding premature wear and extending the lifespan of the bit. The high-quality metal spiral drill bits made from high-performance high-speed steel (HSS) allow for precise drilling in metal. The finely tuned material elasticity ensures high service life and excellent concentricity. The Rapidaptor quick-change chuck allows for bit insertion without the need to engage the sleeve. The bit can be removed by simply pushing it forward, enabling lightning-fast bit changes, even with one hand. The bit holder is suitable for use in a screwdriver or for insertion into the chuck of an electric drill. The Wera 848/851/867/19 metal spiral drill bits and bit set comes in a robust belt pouch.
