The GEARWRENCH Diamond Tip Screwdrivers are engineered with tri-lobe ergonomic handles for improved strength and comfort, and a "speed zone" for fast turning in low-torque applications. The dual-material handle is oil- and solvent-resistant, and the manganese phosphate coated blades offer corrosion resistant. The diamond coated tips provide up to four times the gripping power and reduce cam-out and slippage, the company says. The set of six includes three Phillips-head screwdrivers and three slotted screwdrivers.
