Key Features

Grip Point TipA precision-ground tip seats deeper in the screw recess to cut down on slipping and stripped heads.Increased Torsion ZoneThe shaft flexes slightly under impact torque so the stress does not snap the tip.Impact Driver ReadyBuilt to hold up in cordless and corded impact drivers and drills, not just hand drivers.

Overview

The Diablo 1 in. Slotted #4 Drive Bit (model DSL41P2) is built for pros and serious DIYers. This is a slotted screwdriving bit designed for professional fastening in drills and impact drivers.

Slotted screws are still everywhere in electrical devices, switch plates, older hardware and trim. A slotted bit that stays centered in the slot is the difference between a clean install and a slipped bit across a finished surface.

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 1 in. length and 1/4 in. hex shank fit any quick-change chuck, magnetic bit holder or drill chuck.

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.

Stays Seated, Drives Clean

A tip that fits the recess tightly means fewer stripped screws and less time fighting fasteners.

• Grip Point Tip reduces slipping and stripping
