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.

Rack-A-Tiers 70216RG – Frequently Asked Questions

1) What tip sizes are on the Rack-A-Tiers 70216RG double-end bit?
One end is a Square #1, the other a Square #2 Robertson. Both ends are square (Robertson) recess, so a single bit covers the two square-drive sizes that show up most in panel, device, and box work without swapping bits.
2) Can I run the 70216RG in an impact driver, or is it a drill-only bit?
It is built as an impact drive bit, rated for use in impact drivers and the repeated rotational shock they put through a tip. It will also run in a standard drill/driver, but the reason to buy it is impact duty on panel assembly and rough-in fastening.
3) What is the closest single-tip alternative to the Rack-A-Tiers 70216RG square drive bit?
The Rack-A-Tiers 70216RG is a double-ended impact driver bit with a Square #1 tip on one end and a Square #2 Robertson tip on the other. If you only drive one square size and prefer a single-tip bit, the Milwaukee SHOCKWAVE Impact Duty 2 inch square recess power bit covers square recess driving in a one-ended 2 inch power bit format. The trade-off is straightforward: the 70216RG gives you both #1 and #2 square sizes without reaching back into the bit case, while the SHOCKWAVE square recess bit is dedicated to a single square recess size per bit.
4) Will the Rack-A-Tiers 70216RG drive Phillips screws, or do I need a separate bit?
No. The 70216RG carries square (Robertson) tips only, Square #1 and Square #2, so it will not seat properly in a Phillips recess. For Phillips fasteners you need a Phillips bit such as the Milwaukee 48-32-4802 SHOCKWAVE Impact Duty Phillips #2 power bit in a 6 inch length. Electricians commonly carry both, since device screws and panel hardware mix square and Phillips recesses on the same job.
5) Is a Robertson square bit better than Phillips for electrical device screws?
Square recess geometry seats deeper in the fastener head and reduces cam-out compared with some other drive styles, which is why square-drive screws dominate electrical boxes, panels, and devices in Canadian and much North American electrical work. If you are driving Phillips #2 fasteners instead, a dedicated Phillips bit like the Milwaukee 48-32-4802 SHOCKWAVE Impact Duty Phillips #2 power bit is the right tool; the 70216RG has no Phillips end.
6) What is the part number to order for the Rack-A-Tiers double-end Robertson impact bit?
Order Rack-A-Tiers model 70216RG. It ships as a single double-ended bit, Square #1 on one end and Square #2 on the other, so there is no size or length to specify.
7) I need extra reach to get down into a deep panel enclosure - is the Rack-A-Tiers 70216RG the right bit?
The 70216RG is a compact double-ended bit, with a tip at each end, so it is sized to sit in a bit holder rather than to extend reach on its own. When you need length to reach a fastener recessed in a deep enclosure, a longer single-tip power bit is the better fit - the Milwaukee 48-32-4802 SHOCKWAVE Impact Duty Phillips #2 is a 6 inch power bit for that kind of reach, though it is a Phillips tip rather than square. For square fasteners at depth, pair the 70216RG with a magnetic bit holder extension.
8) Is the Rack-A-Tiers 70216RG rated for an impact driver the same way the Milwaukee SHOCKWAVE bits are?
Yes. The 70216RG is built as an impact drive bit, intended for the repeated rotational shock an impact driver puts through the tip during panel assembly, box mounting, and device installation. Milwaukee's comparable square recess and Phillips bits are part of the SHOCKWAVE Impact Duty series, also made for impact driver use. The difference between them is configuration rather than duty rating: the 70216RG puts two square sizes on one bit body, while the SHOCKWAVE bits are single-tip power bits.
9) Will a double-end bit fit in a magnetic bit holder?
A double-ended bit has a tip on both ends rather than a hex shank with a retaining groove, so it seats in a standard bit holder or chuck with the unused tip inside the holder. Flip it to change sizes. Keep in mind there is no groove for a ball-detent lock, so it relies on the holder's magnet or chuck grip.
10) What jobs is the Rack-A-Tiers 70216RG meant for?
Electrical work, mainly: panel and enclosure assembly, box and device mounting, residential and commercial rough-in and finish, plus any general fastening using square-drive screws. It is sized for a truck stock or pouch kit where you want one bit instead of two.
