Rack-A-Tiers 70216RG Double-End Impact Driver Bit, Square #1/#2 Robertson

Rack-A-Tiers 70216RG Double-End Impact Driver Bit, Square #1/#2 Robertson

The Rack-A-Tiers 70216RG Double-End Impact Driver Bit is built for electricians and tradespeople who need a dependable driving tool that keeps them moving through the workday without swapping bits every few minutes. This double-ended design puts a Square #1 tip on one end and a Square #2 (Robertson) tip on the other, giving installers two of the most commonly used square-drive sizes in a single, compact piece. Because it is engineered as an impact drive bit, the 70216RG is intended to stand up to the torque and repeated shock loads generated by impact drivers on demanding job-site tasks such as panel assembly, box mounting, device installation, and general electrical rough-in and finish work. Having both a #1 and a #2 Robertson tip on hand in one bit reduces the need to carry, sort through, and misplace multiple single-ended bits, which keeps a service truck or tool pouch more organized and speeds up repetitive driving tasks.

Key Features

• Double-Ended Design: Two usable driving tips on a single bit body, cutting the number of individual bits an electrician needs to carry for common square-drive fasteners.
• Dual Drive Sizes: Features a Square #1 tip on one end and a Square #2 Robertson tip on the other, covering two of the most frequently specified square-drive sizes used in electrical and general trade work.
• Impact-Ready Build: Designed as an impact drive bit so it is suited to use with impact drivers, which apply repeated rotational shock to seat fasteners quickly on tougher driving applications.
• Robertson (Square) Drive Compatibility: The square-recess tip geometry helps reduce cam-out compared to some other drive styles, supporting more consistent engagement with the fastener head during repeated driving cycles.
• Job-Site Efficiency: A single double-ended bit means less time spent digging through a bit case for the right size, which helps installers move faster through panel, device, and fixture installation tasks.
• Compact, Grab-and-Go Format: The two-tip configuration is easy to store in a pouch, drill case, or bit holder alongside other commonly used driver accessories on the truck or at the panel.
