Diablo DSQ235P1 3-1/2 Inch SQ2 Square Drive Power Bit Impact Strong MaxTorque Steel Robertson Bit with 1/4 Inch Hex Shank for Cordless Impact Drivers

Drive with professional precision and extreme impact durability

Tackle your most demanding fastening projects with the Diablo DSQ235P1 3-1/2 Inch #2 Square Drive Power Bit. Engineered for the professional tradesperson, these high-performance Robertson-style bits are built to deliver up to 50X longer life than standard bits. The specialized MaxTorque Zone technology acts as a shock absorber, pulling peak torque stress away from the tip to prevent breakage and ensure long-term reliability during high-torque applications. Whether you are installing cabinetry, building decks, or securing structural fasteners, this extended length bit provides the stability and reach needed for the toughest jobs.

Every Diablo driver bit features an Optimized Tip Design, providing a precise and secure "stick-fit" grip that virtually eliminates stripping, wear, and accidental slippage. Constructed with an optimized heat treatment process and finished with a rust-protection coating, this bit remains Impact Strong™ in both corded and cordless impact drivers. The 3-1/2 inch extended length offers superior reach into deep pockets and tight spaces compared to standard 1-inch insert bits, making it the ideal choice for professional-grade construction where precision and durability are paramount.

Specifications

Pro-Tip: Square drive bits are designed to provide a high level of torque without cam-out. To maximize the life of your SQ2 bit, ensure you are using genuine #2 square fasteners. While some multi-drive screws accept both Phillips and Square bits, using a dedicated Square drive bit in a matching fastener provides the tightest fit and prevents the rounding of fastener corners.
