DRIVE WITH PROFESSIONAL PRECISION AND 50X LONGER IMPACT LIFE

Tackle your most demanding fastening projects with the Diablo DT2535P1 3-1/2 Inch T25 Torx Drive Bit. Engineered for the professional tradesperson, this high-performance star power bit is built to deliver up to 50X longer life than standard bits. The specialized Torque Resistant Design acts as an integrated 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 structural decking screws, working on heavy-duty cabinetry, or securing masonry 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 where standard 1-inch bits fail, making it the ideal choice for professional-grade construction where visibility and durability are paramount.

Specifications

Pro-Tip: The extended 3-1/2 inch length of this bit is perfect for driving fasteners into deep-set holes, such as those found in deck framing or pocket-hole joinery. To maximize the life of your T25 bit, always ensure the driver is fully perpendicular to the screw head before applying torque, which ensures the star points seat deeply and prevents premature corner rounding.
