Family-run for over four generations and nearly 240 years, Witte tools is part of the Kirchhoff family group of businesses and specializes in screwdrivers and bits. Renowned for their ergonomic handles, Witte screwdrivers feature ergonomically-advanced, multi-component handles that not only conform to the hand, but are optizmized for torque and speed depending on the size of the fastener involved. Witte bits are made entirely in-house and feature a broad array of tip styles and materials including stainless steel, diamond-coated, titanium-nitride, and impact/torsion bits.
