Overview

The Diablo 1 in. Square #2 Drive Bit with Bit Holder (model DSQ21BHP25) is built for pros and serious DIYers. This is a screwdriving bit designed for professional fastening in drills and impact drivers.

Diablo's next-generation drive bits are built for pros who drive fasteners all day and need bits that last through high-torque work in impact drivers.

The Grip Point Tip is precision-machined to fit the fastener recess tightly, which reduces slipping and stripping. Behind it, the Increased Torsion Zone absorbs the hammering torque of an impact driver so the tip does not crack. Laser markings make the size easy to identify at a glance.

The tic tac style box holds 25 bits of one size with a magnetic bit holder and carabiner, so you can clip your most-used bit to a belt or bag and stop hunting for it.

This is a solid choice for electricians, HVAC and mechanical techs, facilities maintenance crews, installers and anyone doing assembly or service work with a drill or impact driver.
