Our take on the Milwaukee Electric 366 Piece Master Mechanics Hand Tool Set with Pack

The Milwaukee 48-22-9495 is a 366-piece mechanics set built around 1/4-inch, 3/8-inch and 1/2-inch drive sockets, ratchets and combination wrenches, packed in a four-drawer rolling tool box. The ratchets use a 90-tooth head with a 4-degree arc swing, and the wrenches claim a 2.5-degree arc swing with up to 25% more torque. It is a large, heavy, pro-grade kit rather than a starter set. The best new price is $3,244.54 at eBay as of November 4, 2026, with only two stores listing it new, so there is little price competition to shop around.

Pros
  • 366 pieces cover sockets, ratchets and wrenches across three drive sizes

Cons
  • At $3,244.54 it costs far more than most home mechanics need to spend

  • Heavy rolling box is awkward to move up stairs or into a truck
  • Large set includes sizes many casual users will never touch
  • Premium price buys brand and organization, not unique socket technology

Questions and answers

Is the Milwaukee 366-piece set worth it over buying sockets separately?
For a working mechanic who needs 1/4, 3/8 and 1/2-inch drive plus wrenches in one organized box, the bundle saves time and duplicate buying. For occasional home use, a smaller set costs a fraction of the $3,244.54 eBay price.
How does this set compare with Milwaukee's smaller mechanics sets?
This is the master set: 366 pieces, three drive sizes and a four-drawer box. Smaller Milwaukee sets drop drive sizes, wrench coverage and the rolling storage, so they cost much less but leave gaps.
What is in the box besides sockets and wrenches?
The set includes 1/4-inch, 3/8-inch and 1/2-inch drive ratchets and sockets, combination wrenches, and a four-drawer tool box with foam trays. Check the piece list for bit sockets and extensions before buying.
How much does the set weigh and can one person move it?
Milwaukee does not list a set weight, but a loaded four-drawer box with 366 steel tools is heavy. The dolly is rated to 250 lb; plan on two people for stairs.
When is the best time to buy this set?
With only two stores listing it new, discounts are rare. Watch for holiday tool promotions; the current best is $3,244.54 at eBay as of November 4, 2026.
Where is the Milwaukee Electric 366 Piece Master Mechanics Hand Tool Set with Pack cheapest?
