Key Features
Overview
The Diablo 3-1/2 in. Slotted #4 Drive Bit (model DSL435P2) 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 3-1/2 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
- Increased Torsion Zone for impact driver use

Tool Nut's Take
The Diablo 3-1/2 in. Slotted #4 Drive Bit: Pro Bits Without the Premium Price
Diablo's next-generation bits give you a better-fitting tip and impact-rated shaft at a price that makes them easy to keep stocked.
- Who it's for: Pros and serious DIYers who use an impact driver for everyday fastening.
- Why it stands out: Grip Point Tip for fit and an Increased Torsion Zone for impact durability.
- Worth knowing: These are not the diamond-coated Demon line. If you are stripping screws in high-torque work all day, step up to Demon.
