Craftsman Metric Wrench Sets: Combination, Ratcheting and Overdrive

Best for
Mixed SAE and metric hardware in tight spots

The CRAFTSMAN Ratchet Wrenches set (CMMT87220) includes 20 ratcheting combination wrenches split between SAE and metric, with a case. Its 12-point box end uses a 90-tooth gear, which the listing says gives a 4-degree arc swing. In general terms, a higher tooth count means the wrench needs less room to catch the next tooth, so it works where you can only move the handle a little, such as behind a rig’s seat bracket or under a desk frame.

This is the pick if your toolbox has to handle both imperial and metric hardware. The trade-off for a metric-focused buyer is that only part of the set is metric. It has a chrome finish for corrosion resistance, large size markings, meets or exceeds ASME specifications, and carries a full lifetime warranty. If you only work on metric fasteners, the 11-piece metric ratcheting set is the leaner option.

• 90-tooth ratcheting box end with 4-degree arc swing
• SAE and metric sizes in one 20-piece set
• Storage case included
• Full lifetime warranty

Full metric coverage in one kit

The CRAFTSMAN Combination Wrench set (CMMT12068) is the largest metric-only set here, with 20 pieces. Each wrench has an open end and a 12-point box end with a 15-degree offset for extra knuckle clearance. The listing names chrome molybdenum steel and a full polish chrome finish, and it meets or exceeds ASME specifications.

A fixed combination wrench has no mechanism to wear out and usually has a slimmer box head than a ratcheting wrench, which helps on fasteners set into recessed spots. It is the set for someone who wants every common metric size covered, from small hardware to automotive bolts. At 7 pounds it is also the heaviest kit in this list, so it belongs in a garage chest more than a travel bag. For quick spinning of long threads, pair it with a ratchet; our Craftsman 3/8 ratchet guide covers that side.

• 20 metric combination wrenches
• 12-point box end with 15° offset
• Chrome molybdenum steel, full polish chrome
• Large size markings

Best for
Home garages needing core metric sizes

The CRAFTSMAN Wrench set (CMMT12066) carries the same design as the 20-piece set in a 15-piece metric range. It has a 12-point box end, 15-degree offset, full polish chrome finish, large markings and ASME compliance, with a full lifetime warranty listed. The material is listed as chrome vanadium steel rather than the chrome molybdenum named on the 20-piece listing.

For most home users building desks, assembling gear racks or tuning a bike, 15 sizes cover the common bolts without paying for sizes you may rarely use. It gives way to the 20-piece set if you work on cars or machinery that use a wider spread of sizes. The listing does not specify which sizes are dropped compared with the larger set.

The CRAFTSMAN Combination Wrench 7-piece set (CMMT87015) is the smallest kit here, weighing about 2 pounds. It keeps the 12-point box end, 15-degree offset, full-polish chrome finish and large markings of the bigger sets.

It suits a desk drawer or a streaming room shelf, ready for monitor arms, chair bases and furniture bolts. Be aware of two listing issues. The title says metric, but the description calls it an SAE set, and the material field lists polycarbonate, which is likely an error for a chrome-finished wrench. Confirm the sizes on the product page. If you need more than a handful of sizes, the 15-piece set is the better value.

Best for
Freeing rounded or stubborn bolts

The CRAFTSMAN OVERDRIVE 11-Piece Metric Wrench set (CMMT87811) is built around Tight Torque technology. The listing says the open end can remove fasteners rounded up to 50% and the box end up to 70%, and that the design helps prevent rounding in the first place. A long panel design gives more leverage than Craftsman’s raised panel wrenches.

This is the set to reach for when a bolt fights back, whether on an old bike, a garage-sale rack or a car part. It has a gunmetal-chrome finish, quick-find size markings and meets or exceeds ASME specifications. It does not ratchet, so for fast work on clean fasteners the ratcheting sets are quicker. The description refers to it as both an SAE set and an MM set, while the title says metric, so double-check sizes.

• Tight Torque grip on rounded fasteners
• Long panel design for extra leverage
• Gunmetal-chrome finish
• Quick-find size markings

Fast metric work on bikes and rigs

The CRAFTSMAN Ratcheting Wrench set (CMMT87021) is a metric-only 11-piece ratcheting combination set. It uses a 72-tooth ratcheting 12-point box end with a 15-degree offset, a full polish chrome finish and large markings, in chrome vanadium steel.

It is the choice for metric-heavy builders who want ratcheting speed without paying for SAE sizes. Compared with the 90-tooth set, a 72-tooth gear needs a bit more swing per click, so the 20-piece set is better in the tightest spaces. The specifications list an item torque of 72 N m, which appears to repeat the tooth count rather than describe a real torque rating. Pair it with an extension and ratchet from our Craftsman 3/8 extension guide for deeper bolts.
