The 225 Series insulated ball-grip screwdriver is outfitted with a resin coated shank to help prevent electrical circuiting. Other features include a cushion grip that is color-coded for easy tip identification, a fully hardened chrome vanadium steel shank, magnetized high-precision black point tips, and a solid built body for power fastening. In addition, the 225 Series insulated "ball-grip” handle may not look like a conventional style screwdriver but there are many advantages to the palm-grip design. For instance, when gripping the ball-shape handle, an operator can apply their body weight behind each turn for excellent leverage while fastening which results in higher torque output. Also, the built-in cushion finger knurl allows for quick turning and fine tuning of small fasteners. These screwdrivers are durable, reliable, and designed for professional use such as electrical, automotive, industrial work, and general fastening applications. Also, the cross-point models are recommended when working with JIS screws.
