CRAFTSMAN CMMT12108 20-Piece 1/4" Drive Mechanics Tool Set

The CMMT12108 pairs one fixed-head, low-profile 72-tooth ratchet with 18 six-point sockets, nine SAE and nine metric, and one 1/4 inch extension bar, stored in a Craftsman VERSASTACK-compatible case. Craftsman's own product page and an independent Ace Hardware listing both confirm 72 teeth, even though the Amazon title reads 90-Tooth. Ace Hardware also confirms chrome vanadium alloy steel, a step past the generic alloy steel Amazon's spec field lists. The head is up to 25 percent thinner than Craftsman's standard CMMT81747, useful for tight fastener access, and the full polish chrome handle has a knurled grip zone with no rubber sleeve. The set is well-reviewed on Amazon, though no independent forum threads document long-term use. No 3/8 inch or 1/2 inch drive tools or universal joint are included.

Right pick if you want a genuinely fine 72-tooth ratchet for interior trim, dash, and small-fastener work in a 1/4 inch drive footprint, backed by a Craftsman Full Lifetime Warranty at a low price. Skip it if you need suspension, wheel, or engine-mount work covered from one purchase, since every socket and the sole extension bar are 1/4 inch drive only; a 3/8 inch or 1/2 inch set, or a multi-drive kit like the Craftsman CMMT86501V, is the better match for higher-torque fasteners.

Chrome vanadium alloy steel hand tool with no chemical exposure pathway and no SDS; the health score of 9.5 reflects that baseline. All-steel ratchet, extension, and socket bodies recycle through standard metal recycling, and the VERSASTACK-compatible case is single-material plastic with no manufacturer take-back program documented. Socket and torque compatibility for your specific fasteners remains a buyer responsibility separate from this health score.
