TL;DR A 262-piece combination set covering all three drive sizes — 1/4-in, 3/8-in, and 1/2-in — in both SAE and metric, with 92 verified sockets (55 shallow + 37 deep) plus ratchets, combination wrenches, hex keys, and specialty bits. Alloy steel construction; 10 mm metric presence assumed but not confirmed from spec. Zero rounding complaints across 10,207 reviews at 4.7★. Hand-ratchet use only — not rated for impact wrenches. Full Lifetime Warranty from CRAFTSMAN.
What it is and how it performs
The CMMT45309 delivers 92 verified sockets across 1/4-in, 3/8-in, and 1/2-in drive — 55 shallow and 37 deep — plus 24 bit sockets and 2 spark plug sockets. The remaining 145 pieces include 3 72-tooth ratchets (5° arc swing), 24 combination wrenches, 44 hex keys, 66 specialty bits, and various accessories. Coverage is SAE and metric across all three drive sizes, making it capable of oil changes (3/8-in), brake jobs (1/2-in), and small fastener work (1/4-in) without a supplemental purchase. Amazon specs confirm alloy steel construction; Cr-V is not explicitly disclosed by CRAFTSMAN, so the exact alloy is unverified. Point count is not disclosed (12-point assumed). Rounding is a non-issue in the review record: zero complaints across 10,207 reviews at 4.7★. The set is not marketed for impact use and carries standard chrome-finished hand-socket construction — not Cr-Mo, not black-oxide.
Who should buy this — and who should skip it
The right pick for a home mechanic who wants a single kit to handle daily drives across oil changes, brake work, interior electrical, and engine-bay fasteners without managing multiple drive-size sets. All three drive sizes are included, and the VERSASTACK case keeps everything organized and accessible at the work site. Skip if you need confirmed 6-point sockets — the point count is not disclosed and cannot be verified from available sources. Also skip if you plan to use an impact wrench — these are alloy steel hand sockets only; impact-rated sockets require Cr-Mo alloy and black-oxide finish.
Safety and environmental impact
No chemical exposure pathway — alloy steel hand tool with no SDS. Alloy steel is rated for hand-ratchet and breaker-bar use — not for impact wrenches; impact-rated sockets use a different alloy (chrome-molybdenum) and black-oxide finish, and using standard hand sockets on an impact driver risks shattering. Alloy steel is fully recyclable as scrap metal; the plastic VERSASTACK case is not routinely recovered through curbside programs. CRAFTSMAN's Full Lifetime Warranty reduces disposal frequency by enabling socket replacement rather than full-set replacement at end-of-life.
Frequently asked questions
Is the CRAFTSMAN CMMT45309 socket set impact-rated?▾
No. This is a standard alloy steel hand-socket set — rated for use with hand ratchets and breaker bars only. Impact-rated sockets use chrome-molybdenum (Cr-Mo) alloy and black-oxide finish. Using standard hand sockets on an air or electric impact wrench risks shattering.
Does the CRAFTSMAN CMMT45309 include a metric 10 mm socket?▾
The set covers SAE and metric across all three drive sizes (1/4-in, 3/8-in, 1/2-in), but the individual size list is not published by CRAFTSMAN. Based on the 92-socket count across three drive sizes and the complete SAE and metric coverage claim, the 10 mm is assumed present — but it cannot be confirmed from the manufacturer's spec or a community source citing a specific size list.
What does '262 pieces' actually mean — how many are sockets?▾
92 of the 262 pieces are actual sockets (55 shallow + 37 deep). The remaining 170 pieces are 24 bit sockets, 2 spark plug sockets, 3 ratchets, 4 extension bars, 2 adapters, 1 bit driver, 44 hex keys, 24 combination wrenches, 66 specialty bits, and 7 other accessories. This is standard practice for combination mechanics kits, not a defect.
What drive sizes does the CRAFTSMAN CMMT45309 cover?▾
All three standard drive sizes: 1/4-in, 3/8-in, and 1/2-in. The set includes ratchets for each drive size and sockets across all three, covering oil changes (3/8-in dominant), brake jobs (1/2-in for wheel lug nuts and caliper bolts), and small interior fasteners (1/4-in).
Does the CRAFTSMAN CMMT45309 come with a warranty?▾
Yes. CRAFTSMAN offers a Full Lifetime Warranty on this set, confirmed on the Amazon product page. This covers defects in materials and workmanship.
