Rack-A-Tiers 70214RG Square #1 and #2 Steel Double-End Impact Bit, 4-Inch Robertson®

The Rack-A-Tiers 70214RG is a double-end impact driving bit built for electricians and installers who need fast, reliable bit swaps on the job. This bit features a Robertson® Square #1 tip on one end and a Robertson® Square #2 tip on the other, giving you two of the most common square-drive sizes in a single 4-Inch OAL (overall length) tool. Constructed from steel for durability under repeated impact-driver use, the 70214RG is designed to hold up to the torque and vibration generated by impact drivers on demanding electrical and construction tasks. Having both a #1 and #2 Robertson® tip on one bit means fewer bit changes and less clutter in your tool bag or impact driver case.

Key Features

  • Overall Length: 4-Inch OAL provides good reach into recessed screw locations while remaining easy to control in tight spaces.
  • Durable Construction: Steel bit body is engineered to withstand the high torque and repeated impact loads of impact driver applications.
  • Double-End Design: Square #1 tip on one end and Square #2 tip on the other, doubling your available drive sizes without carrying extra bits.
  • Robertson® Square Drive: Square-drive tips are shaped to reduce cam-out and slippage compared to standard driver tips, helping maintain a secure engagement with Robertson®-head fasteners.
  • Impact-Rated Use: Purpose-built as an impact bit, making it suited for use in impact drivers commonly found on electrical and trade job sites.
  • Space-Saving Format: Combining two bit sizes into one double-end tool reduces the number of individual bits you need to stock, sort, and carry.

Technical Specifications

  • Overall Length: 4-Inch OAL
  • Tip Type: Square #1 and Square #2, Robertson®
  • Material: Steel
  • Configuration: Double-End Impact Bit

Typical Applications

  • Electrical Panel and Device Installation

Rack-A-Tiers 70214RG – Frequently Asked Questions

1) Does the Rack-A-Tiers 70214RG bit have both #1 and #2 square drive tips on the same bit?
Yes. The 70214RG is a double-end bit with a Robertson square #1 tip on one end and a square #2 on the other, so you flip it rather than carry two bits. Overall length is 4 inches.
2) Can I run the 70214RG square bit in an impact driver, or is it only for a drill?
It is built as an impact bit. The steel body is made to take the torque and repeated impact loads of an impact driver, which is how electricians typically run it on panel and device work. It will also work in a standard drill/driver.
3) Will this Robertson bit fit Robertson/square-head screws used in Canadian electrical boxes and devices?
Yes, within the two sizes it carries. The 70214RG drives Robertson square-head fasteners in #1 and #2, which are the two sizes you hit most on device screws, box connectors and panel work. If you need #3 square, this bit will not cover it.
4) What is the difference between the Rack-A-Tiers 70214RG and the Milwaukee SHOCKWAVE Impact Duty 2-inch square recess power bit?
Both drive square recess (Robertson) fasteners under an impact driver, but they differ in length and tip count. The Rack-A-Tiers 70214RG is a steel double-end bit 4 inches overall with a Square #1 tip on one end and a Square #2 on the other, so one bit covers both common square-drive sizes. The Milwaukee SHOCKWAVE Impact Duty square recess power bit is a 2-inch single-end bit from Milwaukee's SHOCKWAVE line, so you would carry separate bits for each square size. If you want a shorter bit for tight work inside a panel, the 2-inch Milwaukee is the shorter option; if you want fewer bit changes, the double-end 70214RG does both sizes.
5) I need to drive Phillips #2 screws, not Robertson - what should I use instead of the 70214RG?
The Rack-A-Tiers 70214RG only carries square-drive Robertson tips, Square #1 and Square #2, so it will not engage a Phillips head. For Phillips #2 fasteners under an impact driver, the Milwaukee 48-32-4802 SHOCKWAVE Impact Duty Phillips #2 power bit is the match, in a 6-inch length. Many electricians carry both: the square double-end bit for Robertson-head devices and a Phillips bit for everything else.
6) Is a 4-inch double-end bit too long for working inside a panel or tight box?
Four inches of overall length is a middle ground: enough reach to get down into recessed screws in a panel or deep box, short enough to still steer in close quarters. If you need more reach than that, look to a 6-inch power bit such as the Milwaukee 48-32-4802 SHOCKWAVE Impact Duty, though that one is Phillips #2 rather than square.
7) Do I need a bit holder or magnetic sleeve to use a double-end bit like this?
A double-end bit has a tip on both ends instead of a shank, so it is meant to run in a bit holder or magnetic sleeve chucked into the driver, not clamped directly in a drill chuck. No holder comes with the 70214RG, so order one if you do not already carry it.
8) Which impact bit gives the most reach for deep recessed screws, the 70214RG or the Milwaukee options?
Of the three, the Milwaukee 48-32-4802 SHOCKWAVE Impact Duty Phillips #2 bit is the longest at 6 inches, but it drives Phillips heads. For square-drive Robertson fasteners, the Rack-A-Tiers 70214RG at 4 inches overall gives more reach than the 2-inch Milwaukee SHOCKWAVE square recess power bit, while still staying controllable in tight spaces.
9) What part number and UPC should I order for the Rack-A-Tiers double-end square bit?
Order Rack-A-Tiers MPN 70214RG. The UPC is 625912022140. There is one configuration, so there is no finish, size or tip option to specify.
10) Why pick a square drive bit over Phillips for electrical work?
Square (Robertson) tips sit deeper in the fastener recess and resist cam-out and slippage better than a standard Phillips tip, which matters when you are driving device and panel screws at impact-driver torque. If the screws on your job are Phillips, you need a Phillips bit instead, such as the Milwaukee 48-32-4802 SHOCKWAVE Impact Duty Phillips #2.
