Our take on the Dewalt DWMT45424 Mechanics Set 84 pcs

The DeWalt DWMT45424 is an 84-piece 1/4-inch drive mechanics set built around a 72-tooth ratchet with a 5-degree arc swing and a head about 20% thinner than a standard ratchet. Sockets and accessories are chrome vanadium steel, and the set packs into a molded case for storage and carry. It suits home mechanics and DIYers working on small fasteners, interior trim, appliances and light engine jobs where a compact 1/4-inch drive reaches places a 3/8-inch set cannot. Against rival 1/4-inch sets from GearWrench, Tekton and Craftsman, the thin head and fine ratchet are the selling points; the trade-off is that it covers small fasteners only, so buyers needing lug nuts or suspension work must add a larger drive set.

Questions and answers

Is this set enough for general car repair?
It covers small fasteners, trim and light engine work, but the 1/4-inch drive is too small for lug nuts, suspension or most chassis bolts. Most owners pair it with a 3/8- or 1/2-inch set.
How does the ratchet compare with a standard one?
The head is about 20% thinner and the 72-tooth gear needs only a 5-degree swing, so it fits and turns in tighter spots than a coarse, bulky ratchet.
Does it include deep sockets or a universal joint?
No. The 84 pieces are standard-depth sockets, extensions and the ratchet, so deep sockets and swivels have to be bought separately.
What is the drive size and material?
It is a 1/4-inch drive set made from chrome vanadium steel, which is the common alloy for hand-tool sockets.
Is it a good first tool set?
It is a solid compact starter for small jobs, but a first set for car work should also include 3/8-inch drive sockets and a breaker bar.
Where is the Dewalt DWMT45424 Mechanics Set 84 pcs cheapest?
At The Home Depot, for $79.00, 20% under what the other stores charge, as of our latest check.
