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.Two Tips, One BitFlip the bit end for end to switch sizes without digging through the bit case.

Overview

The Diablo 2-1/2 in. Double-Ended Torx T15/T20 Drive Bit (model DDET15T20P2) is built for pros and serious DIYers. This is a double-ended screwdriving bit designed for professional fastening in drills and impact drivers.

Double-ended bits put two tips on one shaft, so one bit covers the two sizes you switch between most. The longer overall length also gives you a little extra reach into recessed screws.

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 2-1/2 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
