Impact Driver Accessories Worth Owning
An impact driver comes with almost nothing, and the accessory aisle is full of filler. These are the add-ons that earn a place in the bag, and the ones to leave on the shelf.
We research tools from manufacturer specs and long-term owner feedback. If you buy through our Amazon links we may earn a commission at no extra cost to you. How we make money.
The impact driver accessories worth owning are short: impact-rated power bits in PH2, T25 and SQ2, a magnetic bit holder, a set of magnetic nut drivers, a hex-to-square socket adapter set, and impact-rated hex drill bits. Add a right-angle attachment if you work in cabinets or between framing, and a second battery before anything else. Skip giant mixed kits, chrome sockets and anything not labeled impact-rated.

The short list: impact driver accessories worth owning
Most of what makes an impact driver useful is the stuff you put in the collet. A good short list covers nearly every job a homeowner or tradesperson runs into, and none of it is expensive on its own. The skill is in skipping the filler.
| Accessory | Priority | Why it earns its place |
|---|---|---|
| Impact-rated power bits (PH2, T25, SQ2) | Must have | Cover most screws; survive impact |
| Magnetic bit holder | Must have | Runs every insert bit in your set |
| Magnetic nut drivers (1/4, 5/16, 3/8 in) | Must have | Hex-head self-drillers and small bolts |
| Second battery | Must have | No downtime while one charges |
| Hex-to-square socket adapters | High | Use your socket set for lags and bolts |
| Impact-rated hex drill bits | High | Pilot holes without swapping tools |
| Mixed impact bit set | High | Odd sizes: Pozidriv, hex keys, small Torx |
| Right-angle attachment | Situational | Cabinets, joists, tight corners |
| Spade bits | Situational | Wire and pipe runs through framing |
| Holster or bit belt clip | Optional | Ladders and roofs |
Bits: buy few, buy impact-rated
Start with 2-inch impact-rated power bits in PH2, T25 and SQ2, in multi-packs for whichever you use most. Add T20 and T30 if you build decks or fences. Then buy one compact mixed set for the odd sizes. Regular bits snap and wear under impact; the reasons are in impact-rated vs regular bits.
The full bit system, including starter kits and sizes, is in the impact driver bits guide, and specific sets are compared in the best impact driver bit sets.

Holders, nut drivers and socket adapters
Magnetic bit holder
A holder turns 1-inch insert bits into usable bits and holds screws on the tip. Get an impact-rated holder about 2 inches long, and add a sleeve-type screw guide if you drive long screws or work overhead. Types and lengths are covered in magnetic bit holders.
Magnetic nut drivers
A 5/16-inch magnetic nut driver drives most hex-head self-drilling screws used in metal roofing, HVAC and steel studs. Add 1/4 and 3/8 inch and you cover most small hex heads. Weakness: magnets collect metal shavings, so wipe them often.
Socket adapters
A three-piece set in 1/4, 3/8 and 1/2-inch drive lets you run your sockets from the driver. Use impact-rated adapters and impact sockets. Ball detents, wobble and torque limits are in impact driver socket adapters.

Drilling and boring accessories
An impact driver is not a drill, but it handles pilot holes and wood boring well with the right bits:
- Impact-rated hex twist bits from 1/16 to 1/4 inch for pilot holes in wood and thin metal.
- Countersink bits for trim, cabinets and deck boards.
- Threaded-tip spade bits for running wire and pipe through studs.
- A hex step bit for sheet metal and electrical boxes.
What works and what breaks is in drill bits for impact drivers.
Right-angle heads, extensions and reach tools
A right-angle attachment fits where the driver body cannot, such as inside base cabinets, between joists or behind plumbing. Get one that is labeled impact-rated; many drill-only heads strip their gears quickly under hammering. Expect a limit on torque and some added length. Options and limits are in right-angle impact driver attachments.
A 6-inch impact extension or long power bit handles deep holes and screws between framing. Keep extensions short to avoid wobble. Flexible shaft extensions are for drills and light screwdriving, not impact work.
Batteries, holsters and storage
- A second battery is the most useful thing you can add to a bare tool or one-battery kit. A compact pack keeps the driver light; a larger pack helps on long deck jobs. See the impact driver battery guide.
- A holster or belt hook is worth it for ladder and roof work. Most drivers have a clip already.
- A small bit case keeps power bits sorted. Pick one where bits are held by size and visible at a glance. A clear case beats a jumble in a coffee can.
A sensible buying order
You do not need everything on day one. Buy in the order that the jobs show up:
- Day one: PH2 and T25 power bits, a magnetic holder and a 5/16-inch nut driver. That covers drywall, furniture, general wood screws, deck screws and most hex-head self-drillers.
- First project: a compact mixed impact bit set and a few hex pilot bits, so odd screws and pilot holes do not stop the job.
- First bolts or lags: a hex-to-square adapter set and a handful of impact sockets in the sizes you actually use.
- When the battery runs out mid-job: a second battery.
- When you hit a tight spot: a right-angle attachment. Many people never need one; cabinet installers and plumbers use them weekly.
Buying this way means every accessory is matched to a real job. It also stops you paying for a kit full of sizes that sit in the case. Owner feedback on large bargain kits often reports the same pattern: two or three bits wear out quickly and the rest go unused.
Look after what you buy
Accessories last longer when you keep them clean and sorted. Wipe metal filings off magnets, toss rounded bits instead of keeping them in the case, and check holders and adapters for cracks before heavy work. A worn accessory costs more in stripped screws than a replacement costs.
What to skip
| Skip this | Why | Buy instead |
|---|---|---|
| Giant 100-plus piece kits | Mostly sizes you never use; often non-impact steel | Power bit packs in your top sizes plus a compact set |
| Chrome sockets and adapters | Can crack under impact | Black impact-rated sockets |
| Drill-only right-angle heads | Gears fail under hammering | An impact-rated right-angle attachment |
| Flexible shaft extensions | Not built for impact; whip and wear | A short impact extension or right-angle head |
| Masonry bit sets for the driver | No forward hammer action | A hammer drill |
| Keyless chuck adapters for regular drilling | Wobble and length | Hex-shank bits, or a drill |
| Off-brand battery adapters | Can void warranties and bypass protections | Brand batteries |
The pattern behind the skip list: anything that was designed for a drill, a hand ratchet or a gift box tends to fail under impact. If it does not say impact-rated, assume it is not.
Safety: non-impact accessories can crack and throw fragments. Wear eye protection with any impact driver, and hearing protection for long sessions.
Frequently asked questions
What accessories come with an impact driver?
Usually very few. A bare tool includes the driver and sometimes a belt clip. Kits add batteries, a charger and a bag or case, and sometimes one or two bits. Plan to buy bits separately, since the included ones are often basic.
Do I need an impact driver holster?
Only if you carry the driver for long stretches on a ladder or roof. The built-in belt clip on most models works for short jobs. A holster helps on framing and roofing sites. Many people never buy one.
Is a keyless chuck adapter worth it?
For occasional round-shank drill bits, it is a cheap convenience. It adds length and wobble, and most are not built for hammering. If you drill often, use a drill. If you drill a little, buy hex-shank bits instead.
Should I buy brand-matched accessories?
Not necessarily. Bits, holders and adapters with a 1/4-inch hex shank fit every brand. Buy on quality and impact rating, not logo. Batteries and battery-powered add-ons are the only accessories that must match the tool brand.
