Maximises utilisation of material properties using a geometry designed to meet extreme working demands. TriTorsion system is designed to absorb impact forces and thereby protect the bit tip, greatly enhancing the service life of the bit. Impaktor bits also feature miniature diamond particles on the tip of the bit that bite into the screw, creating a secure fit and preventing any slippage. This secure fit means that less contact pressure is required, greatly delaying user fatigue in power tool applications.
