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.

Technical Specifications

  • Drive Type: #1/#2 Square (Robertson®) and #1/#2 Phillips, double-ended
  • Length: 4-Inch
  • Rated For: Impact driver use
  • Color: Blue or Green

Typical Applications

  • Electrical Panel and Enclosure Assembly

Why Rack-A-Tiers?

Rack-A-Tiers builds tools and accessories aimed squarely at the needs of working electricians, and the 70124GB double-ended impact bit reflects that focus by consolidating two of the most-used driver types into one compact, impact-rated piece. Having a #1/#2 Square (Robertson®) and #1/#2 Phillips tip on a single 4-Inch bit means fewer bit changes and less downtime on the job. Offering the bit in both Blue and Green color options gives electricians and crew leads an easy way to keep tools organized and identifiable across a jobsite without changing the drive performance or build quality. For electricians who rely on impact drivers throughout the day, a purpose-built bit like the 70124GB helps keep the work moving without sacrificing fastener fit or driver control.

Rack-A-Tiers 70124GB – Frequently Asked Questions

1) Does the Rack-A-Tiers 70124GB impact bit drive both square (Robertson) and Phillips screws?
Yes, that's the point of it. The 70124GB is double-ended: a #1/#2 square (Robertson) tip on one end and a #1/#2 Phillips tip on the other, so you flip the bit instead of swapping bits when you move between device screws and Phillips fasteners.
2) Can I run this bit in an impact driver, or is it for a drill/driver only?
It's an impact-rated bit, built for the high-torque, high-vibration output of an impact driver. It'll run in a standard drill/driver too, but the construction is aimed at daily impact use on electrical rough-in and finish work.
3) What is the difference between the Rack-A-Tiers 70124GB and the Milwaukee SHOCKWAVE Impact Duty Phillips #2 power bit?
The Rack-A-Tiers 70124GB is a double-ended bit with a #1/#2 square (Robertson) tip on one end and a #1/#2 Phillips tip on the other, 4 inches overall, so one bit covers both fastener drives without a change-out. The Milwaukee 48-32-4802 is a single-ended Phillips #2 power bit in a 6-inch length, so it drives only Phillips but reaches deeper into a recessed panel or enclosure. Choose the 70124GB when a crew is switching between square and Phillips device screws all day; choose the longer Milwaukee bit when the fasteners are Phillips only and sit down inside a deep box.
4) Is this 4-inch Rack-A-Tiers bit long enough to reach device screws down in a deep box or panel?
At 4 inches overall, the 70124GB reaches recessed fasteners in panels, boxes, and enclosures without needing a bit holder extension. Compare that to a standard 2-inch power bit, which often leaves the chuck fouling the box ring on deep-set screws.
5) Will a #1/#2 square tip fit the green ground screws and receptacle screws I run all day?
The #1/#2 sizing on both the square (Robertson) and Phillips ends covers the common screw sizes found on electrical devices, boxes, and hardware, which is where most receptacle, switch, and ground screws sit. If you're driving larger structural or lag-style Phillips fasteners, step up to a dedicated #3 bit.
6) Should I buy a double-ended bit or single-tip power bits for my impact driver?
A double-ended bit like the 70124GB makes sense when you're alternating between square and Phillips all day, as on device trim-out, because you flip it instead of digging for another bit. Single-tip power bits make more sense when you're driving one fastener type for hours or need a size outside #1/#2, for example the Milwaukee SHOCKWAVE Impact Duty Phillips #2 power bit in a 6-inch length for extra reach, or the SHOCKWAVE 2-inch square recess bit for tight quarters.
7) I only drive square-drive screws. Do I need a double-ended bit?
No. If every fastener on the job is square recess, a dedicated bit is the simpler pick: the Milwaukee SHOCKWAVE Impact Duty 2 inch square recess power bit is a single-purpose impact bit for square-drive screws. The Rack-A-Tiers 70124GB earns its keep when the same installer hits both square (Robertson) and Phillips heads, since it carries a #1/#2 square tip on one end and a #1/#2 Phillips tip on the other in a single 4-inch piece.
8) Which bit reaches a screw at the bottom of a deep enclosure?
Length is the deciding spec. The Rack-A-Tiers 70124GB is 4 inches overall, which clears most recessed fasteners in panels, boxes, and enclosures. The Milwaukee 48-32-4802 SHOCKWAVE Impact Duty Phillips #2 power bit is a 6-inch bit, giving more standoff between the driver chuck and the work for the deepest pockets. The Milwaukee 2 inch square recess SHOCKWAVE bit is a short insert-style length better suited to open, accessible screws.
9) What is this driver bit made of?
Steel. It's a single-piece, double-ended bit, so there is no insert and holder to separate or wobble under impact.
