Rack-A-Tiers 70124GB Double-Ended Impact Bit, #1/#2 Square/Phillips/Robertson, 4-Inch

Rack-A-Tiers 70124GB Double-Ended Impact Bit, #1/#2 Square/Phillips/Robertson, 4-Inch

The Rack-A-Tiers 70124GB is a double-ended impact-rated driver bit built for electricians and installers who need a single tool that covers multiple fastener types on the job. This 4-Inch bit combines a #1/#2 square (Robertson®) tip on one end and a #1/#2 Phillips tip on the other, giving installers two of the most common fastener drives in a single, compact piece. Designed for use with impact drivers, the 70124GB is intended to stand up to the repeated torque and vibration of daily electrical rough-in and finish work, reducing the need to carry and swap multiple single-purpose bits. This listing is available in two color options, Blue and Green, so crews can color-code bits across trucks, pouches, and team members while keeping the same drive configuration and impact-rated build.

Key Features

• Trade Size: 4-Inch overall length for reaching recessed fasteners in panels, boxes, and enclosures.
• Double-Ended Design: #1/#2 Square (Robertson®) drive on one end and #1/#2 Phillips drive on the other, eliminating the need to switch bits between fastener types.
• Impact-Rated Construction: Built to hold up under the high-torque, high-vibration output of impact drivers commonly used in electrical installation work.
• Versatile Fastener Compatibility: #1/#2 sizing on both drive styles covers a wide range of screw sizes typically found on electrical devices, boxes, and hardware.
• Compact, Jobsite-Ready Format: Single-piece, double-ended profile keeps tool bags and pouches organized by combining two drive types into one bit.
• Color Options: Available in Blue and Green so crews can visually sort or color-code bits by user, truck, or task while every option shares the same drive configuration, length, and impact rating.
