• Since the torsion zone absorbs the impact when force is applied, the product lasts for a long time.
• When the torque peak is reached, the torsion zone of the bitorsion bit absorbs the kinetic energy and avoids the torsion of the drive chip. Therefore, it can be used for a long time without breaking the tool.
• Bella's Vitorsion Bit is a special steel that has been subjected to Bella's unique quenching treatment and is designed to resist twisting and last a long time.
