A coating with diamond-sapphire particles and an elastic torsion zone characterise the fischer diamond torsion bit FDB. The coating with diamond-sapphire particles ensures a safe transfer of force and prevents the bit tip from slipping out of the screw head. The tapered bit shank acts as an elastic torsion zone in the case of extreme loads. fischer offers an extensive assortment of high-quality special bits with the internal drives PH, PZ, and TX in different profile sizes and lengths.
