Diablo’s driver bit range of Phillips bits delivers maximum performance, extreme durability and up to 50X longer life when installing and removing fasteners. An optimized tip design provides a strong, precise grip that reduces wear, stripping and slippage. MaxTorque Zone delivers ultimate torque resistance by absorbing torque, creating less stress at the tip when tightening and removing nuts and screws. This range is Impact Strong, delivering increased shank stability and durability in cordless and corded impact and drill drivers.Extreme durability and impact resistance for up to 50X longer life versus standard bitsMaxTorque Zone ultimate torque resistance absorbs torque for less stress at the tipOptimized tip design reduces wear, minimizes breakage and prevents slippageImpact Strong increases shank stability and durabilityRust protection coating for excellent wear and corrosion resistanceLaser engraved bit type and size for easy identificationOptimized heat treatment process strengthens the bit for impact resistance and stabilityMaximum stability in cordless and corded impact and drill drivers
