Rack-A-Tiers 70224BR Square #2 Double-End Impact Bit, 4-Inch OAL

The Rack-A-Tiers 70224BR is a Square #2 double-end impact driver bit built for electricians and installers who need a dependable fastening tool on the jobsite. With an overall length of 4-Inch, this double-end bit gives you a Square #2 drive tip on each end, doubling your usable bit life before a swap is needed. It's designed to be chucked directly into impact drivers for fast, repeatable driving of Square-drive fasteners commonly used in electrical box installation, conduit strap mounting, panel work, and general low-voltage and line-voltage rough-in tasks.

Key Features

  • Overall Length: 4-Inch OAL provides extra reach for recessed screws and deeper fastening applications where a standard short bit won't reach.
  • Drive Type: Square #2 tip delivers a secure, slip-resistant fit on Square-drive fasteners, reducing cam-out and stripped screw heads during high-torque impact driving.
  • Double-End Design: Two usable driving ends on a single bit body means twice the wear life per bit and fewer bit changes during a long install run.
  • Impact-Rated: Built to be used with impact drivers, this bit is intended to handle the rotational shock and pulsed torque generated by impact tools without premature failure.
  • Universal Chuck Compatibility: Standard hex shank design allows the bit to be used in common 1/4-Inch hex impact driver chucks and quick-change bit holders found on most cordless impact drivers.
  • Jobsite-Ready: Sized and shaped for daily use by electrical contractors, low-voltage installers, and maintenance techs who need a reliable driving bit they can grab and use immediately.

Rack-A-Tiers 70224BR – Frequently Asked Questions

1) Will the Rack-A-Tiers 70224BR bit fit my cordless impact driver chuck?
Yes. The 70224BR uses a standard hex shank that drops into 1/4 inch hex impact driver chucks and quick-change bit holders, so it works in common cordless impact drivers without an adapter.
2) What is the closest alternative to the Rack-A-Tiers 70224BR Square #2 impact bit?
The Milwaukee SHOCKWAVE Impact Duty 2-inch square recess power bit is the nearest match on drive tip, since both drive Square #2 fasteners under impact. The difference is configuration and reach: the 70224BR is a double-end bit at 4-inch overall length, giving two usable Square #2 tips on one body, while the Milwaukee square recess bit is a 2-inch single-end power bit. If the fasteners sit recessed in an electrical box or behind a strap, the 4-inch Rack-A-Tiers body reaches where a 2-inch bit will not.
3) Is the Milwaukee 48-32-4802 a substitute for the Rack-A-Tiers 70224BR?
No. The two bits drive different fastener heads. The 70224BR is a Square #2 tip and the Milwaukee 48-32-4802 is a Phillips #2 tip, so they are not interchangeable on the same screws even though both are impact-rated bits that chuck into a 1/4-inch hex impact driver. Match the bit to the screw head you are driving.
4) Is a 4-inch double-end bit too long for tight work in a panel?
At 4 inches overall it gives reach into recessed screws and deeper boxes that a 1-inch insert bit cannot touch, but that same length costs you clearance in a crowded gutter or against a nearby stud. For close quarters, a short 1 or 2 inch insert bit in a holder is easier to swing. Note that a double-end bit cannot be shortened by seating it deeper, since both ends are driving tips.
5) What is the advantage of a double-end bit over a standard power bit?
Two driving tips on one body. When the first Square #2 end rounds over, you flip the bit and keep going, which doubles usable life per bit and means fewer stops to swap during a long run of fasteners. The trade-off is that there is no plain shank to grip, so it has to be chucked by one of the tips.
6) Is this bit rated for impact drivers or just drills?
The 70224BR is built for impact use, intended to take the rotational shock and pulsed torque of an impact driver rather than failing early the way a plain drill-rated bit does. It will also run fine in a standard drill or screwgun.
7) I need a Phillips #2 impact bit instead of square drive, what should I get?
Square #2 will not drive a Phillips head. For Phillips fasteners, the Milwaukee 48-32-4802 SHOCKWAVE Impact Duty Phillips #2 power bit is a 6 inch length impact bit that covers the same kind of fastening work.
8) What else does ZenSupply carry in a square #2 impact bit if I want a shorter one?
Milwaukee's SHOCKWAVE Impact Duty 2 inch square recess power bit is the shorter square #2 option. It is single-ended rather than double-ended, so you get one tip instead of two, but the shorter body is handier inside boxes and enclosures where 4 inches is more than you need.
