The Diablo DSDT102P2 Demon 2 in. T10 Torx Drive Bit is a premium Torx screwdriving bit built for pros who drive a lot of fasteners and are tired of stripped heads. This is a Torx drive bit designed for high-torque fastening in wood, metal and general construction with impact drivers and drills. It comes as a 2-pack so you have a spare ready when the first one finally gives up.

Demon is Diablo's top-tier bit line, and the difference is the tip. Tru Diamond Grit is a real diamond coating on the tip that increases friction for up to 50X more grip than a standard bit. On the job that means the bit stays engaged in the T10 Torx recess when you lean on an impact driver, instead of riding up and chewing the head of the screw.

That same coating protects the tip from wear, delivering up to 100X longer life in demanding screwdriving. A precision Grip Point Tip seats tightly in the fastener, and the Increased Torsion Zone in the shaft flexes to soak up impact torque so stress does not concentrate at the tip where bits usually crack.

Impact Strong construction and an optimized heat treatment strengthen the core of the bit, and a rust protection coating keeps it working in damp jobsite conditions. Laser-engraved size markings stay readable after the paint wears off. Color-coded Torx rings make the size readable at a glance.

The 2 in. length is the everyday workhorse size: long enough to clear a bit holder or chuck, short enough to keep the driver close to the work. The 1/4 in. hex shank fits any quick-change chuck, magnetic bit holder or drill chuck.

Buy this if you are framing, decking, installing cabinets, running electrical or doing mechanical work where Torx screws go in all day. If you are burning through standard bits every week, the Demon line is where the cost per screw comes down.
