A ratcheting wrench is the tool that makes people wonder how they ever worked without one. Instead of lifting the wrench off the nut and repositioning it every few degrees, you just swing back and forth. In a cramped engine bay where a standard wrench can only move a few degrees, that difference turns a 20-minute job into a 5-minute one.
The best ratcheting wrench set for you comes down to three choices: how small a swing arc you need (set by the tooth count), whether you want a fixed head, a flex head or a reversing lever, and how far the size range goes. For car work, metric 8 to 19 mm is the minimum; 8 to 22 mm is better.
We compared current sets from GearWrench, Milwaukee and Craftsman on those points, using manufacturer specs. GearWrench appears often here for a reason: the brand began in 1996 with its original ratcheting wrench and still has the deepest lineup. Our GearWrench tool set review covers the rest of the brand.

The Best Ratcheting Wrench Sets, Reviewed
1. GearWrench 86927 90-Tooth Metric Set: Best Overall
Who it's for: home and pro mechanics who want one metric ratcheting combination wrench set that does everything well.
This is GearWrench's newer 90-tooth design, and it's an upgrade over the classic 72-tooth line in every way that matters. The 12-point box end needs just 4° of swing, and off-corner loading on both the box end and the open end reduces rounding. GearWrench also made the beam longer and wider than its older wrenches for more reach and a more comfortable grip.
The set covers every metric size from 8 to 19 mm with large color-coded markings, and it ships in a solvent-resistant compact rack with drop-in placement. GearWrench says the wrenches exceed ASME torque performance requirements and lists a full lifetime warranty. If you need SAE, the 86958 is the 10-piece twin from 1/4" to 3/4".
Pros
- 90-tooth box end with a 4° swing
- Off-corner loading on both ends
- Gap-free 8 to 19 mm
- SAE twin available (86958)
Cons
- Stops at 19 mm
- Thicker beam than the classic 9412

2. GearWrench 9412 72-Tooth Metric Set: Best Value Classic
Who it's for: budget-minded buyers and anyone who wants the thinnest possible head.
The 9412 is the GearWrench ratcheting wrench set most mechanics picture: 12 metric wrenches from 8 to 19 mm with a 72-tooth, 12-point ratcheting box end. GearWrench rates it at 5° of swing, compared with about 30° for a standard wrench. The thin head and beam are its quiet advantage, because they slip into gaps the newer, beefier designs can't.
Sizes are stamped on both ends of the beam, the finish is full polish chrome, and the set comes in a plastic tray. It doesn't have the newer off-corner open end of the 90-tooth line, but it does have off-corner loading on the box end and a full lifetime warranty.
Pros
- Proven 72-tooth design
- Thin head and beam for tight gaps
- Gap-free 8 to 19 mm
Cons
- 5° swing, versus 4° on the 90-tooth sets
- Basic plastic tray

3. GearWrench 86727 90-Tooth Flex Head Set: Best Flex Head
Who it's for: anyone who works on bolts behind engines, under dashboards or along frame rails where a straight wrench can't line up.
This is the flex head ratcheting wrench set version of our top pick. You get the same 90-tooth, 4° box end, the same dual-direction off-corner open end and the same longer, wider beam, plus a flexible head that pivots to reach fasteners at an angle. It covers 8 to 19 mm in 12 pieces and comes in GearWrench's compact rack. The SAE version is the 10-piece 86758 (1/4" to 3/4").
A flex head is a trade-off: it reaches more fasteners but can flop when you'd rather it stayed straight. If that bothers you, GearWrench's 85698 XL set has a locking flex head, though it uses the older 72-tooth mechanism.
Pros
- Flexible head for angled access
- 90-tooth, 4° swing
- SAE twin available (86758)
Cons
- Non-locking flex can move when you don't want it to
- Longer overall than a fixed-head wrench

4. Milwaukee 48-22-9516 15-Piece Metric Set: Best Size Range
Who it's for: mechanics who want ratcheting wrenches up to 22 mm and the smallest swing in a mainstream fixed-head set.
Milwaukee's ratcheting combination wrenches use double-stacked pawls for 144 ratcheting positions and 2.5° of swing, finer than any GearWrench set here. The 15-piece metric set runs every size from 8 to 22 mm, which adds the 20, 21 and 22 mm sizes most 12-piece sets leave out.
The open end uses Milwaukee's MAX BITE design, which the company says gives up to 25% more torque than smooth-faced wrenches, and the I-beam handle has ink-filled size labels. The set comes in a tray designed for steel tool chest drawers, with Milwaukee's Lifetime Guarantee. The SAE version is the 48-22-9416 (1/4" to 1"), and Milwaukee also sells a flex head metric set (48-22-9513) in the same 8 to 22 mm range.
Pros
- 2.5° swing with 144 positions
- Gap-free 8 to 22 mm
- Lifetime Guarantee
Cons
- Premium price
- Fixed head only in this set

5. Craftsman V-SERIES CMMT87350V SAE Reversible Set: Best Reversible
Who it's for: SAE users, especially on older domestic vehicles, small engines and equipment, who want to switch direction without flipping the wrench.
Craftsman's V-SERIES is its professional-grade line. This set includes eight reversible ratcheting combination wrenches from 5/16" to 3/4", each with a 72-tooth, 12-point box end for a 5° swing and a 15° box-end offset for knuckle clearance. The I-beam handle keeps weight down without giving up strength, and the low-profile head helps in tight spots.
The vertical wrench rack is designed to fit most metal tool chest drawers, which is better storage than most sets include. Craftsman lists a full lifetime warranty. If you want a metric reversible set, GearWrench's 9620N (8 to 19 mm, 72-tooth, flush-mounted reversing lever, 15° offset) is the equivalent.
Pros
- Reversing lever for quick direction changes
- 15° offset box end
- Drawer-friendly vertical rack
Cons
- SAE only, eight sizes
- 72-tooth, 5° swing

6. GearWrench 86229 120XP Universal Spline XL Flex Set: Best Premium
Who it's for: professionals and serious DIYers who want one set that grips nearly any fastener head and reaches farther.
The 86229 combines three upgrades. The 120XP mechanism uses two stacked 60-tooth pawls for 120 positions and a 3° swing. The Universal Spline box end fits 12-point, 6-point, rounded 6-point, spline, External Torx and square fasteners, which helps on worn hardware. And the XL beam is up to 25% longer than standard GearWrench wrenches for more reach and leverage.
It covers 8 to 19 mm in 12 pieces with a flex head, recessed color-coded markings and a wrench rack. GearWrench lists a full lifetime warranty. The SAE version is the 11-piece 86247 (1/4" to 3/4").
Pros
- Universal Spline grips worn and non-hex fasteners
- 3° swing with 120XP
- XL length for leverage and reach
Cons
- Long wrenches can be awkward in very tight spaces
- Premium price

Ratcheting Wrench Set Buying Guide
Tooth Count and Swing Arc
The swing arc is the minimum handle movement needed to catch the next tooth. Lower is better in tight spots. Here's how the designs compare, using manufacturer figures:
| Mechanism | Swing arc |
|---|---|
| Standard (non-ratcheting) wrench | About 30°, per GearWrench |
| 72-tooth | 5° |
| 90-tooth | 4° |
| GearWrench 120XP | 3° |
| Milwaukee 144-position | 2.5° |
For general car work, 72-tooth is fine. If you spend time in crowded engine bays, 90-tooth or finer is worth it.
Fixed Head, Flex Head or Locking Flex
A fixed head is the strongest and most predictable. A flex head reaches angled fasteners but can flop. A locking flex head, like GearWrench's 85698 XL set, holds a set angle. Most people should start with a fixed set and add flex wrenches in the sizes they use most.
Reversible or Flip-to-Reverse
Non-reversible ratcheting wrenches change direction when you flip them over. That's fine in the open, but in tight spots you may not have room to pull the wrench off and flip it. A reversing lever, like on the Craftsman CMMT87350V or GearWrench 9620N, solves that.
Size Range and Gaps
For metric car work, 8 to 19 mm is the minimum. Sets that go to 22 mm, like Milwaukee's 15-piece, cover larger suspension and brake hardware. Our socket size chart shows why SAE wrenches aren't a substitute for missing metric sizes.
Head Thickness and Beam Length
Thinner heads fit tighter gaps; the classic GearWrench 9412 is notably slim. Longer beams like GearWrench's XL design give more leverage but can be harder to swing in a confined space. For really tight spots, see our thin wrench set guide.
Open-End Design
The open end matters because you'll use it constantly. GearWrench's 90-tooth and 120XP lines add off-corner loading to the open end, and Milwaukee's MAX BITE open end is designed for extra grip. Both help on worn fasteners.
Storage
Racks and trays keep sets complete. GearWrench's compact rack, Milwaukee's drawer tray and Craftsman's vertical rack all fit in a tool chest drawer. Loose wrenches in a drawer tend to vanish one size at a time.
Use the Right Tool to Break Bolts Loose
A ratcheting wrench is for speed. For seized or high-torque fasteners, break them loose with a standard combination wrench or breaker bar first. That protects the ratchet mechanism and your knuckles. A good standard wrench set is the perfect partner.
How We Chose
We compared current ratcheting combination wrench sets from GearWrench, Milwaukee and Craftsman using each manufacturer's published specs: included sizes, tooth count and swing arc, fixed, flex or reversible design, open-end features, beam length, storage and listed warranty. We weighted gap-free metric coverage and small swing arcs most heavily for automotive use, and we considered recurring owner feedback on flex-head behavior and storage. We did not test these sets ourselves.
FAQ
Is a GearWrench ratcheting wrench set worth it?
For most home mechanics, yes. GearWrench was built on the ratcheting wrench, which it launched in 1996, and still sells the widest range, from the classic 72-tooth 9412 to 90-tooth and 120XP sets, all with a full lifetime warranty on its spec sheets. Its 90-tooth 86927 is our top pick.
Flex head or fixed head ratcheting wrench: which is better?
Fixed head for your first set. It's simpler, feels more solid and is easier to control. A flex head ratcheting wrench set adds access to fasteners at awkward angles, like bolts behind an engine or on the back of a transmission, so it makes a great second set.
What is the difference between 72-tooth and 90-tooth ratcheting wrenches?
Swing arc. A 72-tooth mechanism needs 5 degrees of handle movement to engage the next tooth; a 90-tooth needs 4 degrees. GearWrench's 120XP design needs 3 degrees and Milwaukee's 144-position wrenches need 2.5 degrees. Smaller numbers help in tight spaces.
Can a ratcheting wrench break loose a tight bolt?
It can, but it isn't the best tool for it. A seized fastener puts the full load on the ratchet mechanism. Break stubborn bolts loose with a standard combination wrench or a breaker bar, then use the ratcheting wrench to spin them out quickly.
Do I need a reversible ratcheting combination wrench set?
Not necessarily. Non-reversible wrenches change direction when you flip them over, which works fine in open areas. A reversing lever saves time in tight spots where you can't remove and flip the wrench, which is why many mechanics keep a reversible set for engine-bay work.
Verdict
The GearWrench 86927 is the best ratcheting wrench set for most people: a 90-tooth, 4° box end, off-corner grip on both ends and every metric size from 8 to 19 mm. If you want more range and the finest swing, Milwaukee's 48-22-9516 runs to 22 mm at 2.5°; see our Milwaukee mechanic tool set review for the rest of that lineup.
