TL;DR A 20-piece dual-standard combination ratchet wrench set with a 90-tooth mechanism · 4° arc swing per advance, confirmed from manufacturer spec. Covers the full SAE range (1/4·3/4 in) and full metric range (6·18 mm) in one set. Chrome-vanadium steel with polished finish; Kobalt lifetime warranty confirmed honored at brand level across owner reports spanning 2019·2026. Well-regarded by owners, though on a still-modest review base.
A 20-piece set of combination ratchet wrenches · each wrench has a standard open end on one side and a 90-tooth ratcheting 12-point box end on the other. The 90-tooth mechanism produces 4° of arc swing per advance, stated explicitly in the manufacturer feature bullet. Ten SAE wrenches cover 1/4 through 3/4 inch; ten metric wrenches cover 6 through 18 mm. Steel is chrome-vanadium confirmed from the listing specification field. Handles are polished Cr-V steel with no rubberized grip sleeve. No extension bars · this is a wrench format, not a socket-drive set; extension bars are not applicable. Well-reviewed by owners across a span from 2019 through 2026, though on a still-modest review base; no mechanism failure reports documented by owners.
The right pick for a home mechanic or car owner who works on both domestic and imported vehicles and wants a single ratcheting wrench set that covers the full size range for both measurement standards without needing to swap between two sets. The 90-tooth mechanism and 4° arc swing make this usable in tight engine-bay and undercarriage spaces where a standard open-end wrench cannot turn continuously. Skip this if the primary need is a socket ratchet with interchangeable sockets and extension bars for deep-reach work · a dedicated 3/8- or 1/2-inch drive socket set handles that use case. Also skip if a flex-head ratcheting wrench is needed for angled access; this set uses fixed-head geometry only.
Chrome-vanadium steel hand tool · no chemical exposure pathway; no SDS. Chrome-vanadium steel is fully recyclable through standard metal recycling at end of life. The rail-style molded holder keeps wrenches separated and prevents contact wear between tools during storage. Any chemical products used alongside these wrenches · penetrating oil, thread locker, lubricant · carry their own hazard profiles; check the individual product page for PPE guidance on those products.
90 teeth · confirmed from the manufacturer feature bullet: '90-tooth ratcheting end provides 4° of arc swing.' 90 teeth means the ratcheting box end needs only 4° of handle movement to advance one tooth, which is the key specification for tight-space work where hand-swing clearance is limited.
Yes. The 20-piece set includes 10 SAE wrenches (1/4, 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, and 3/4 inch) and 10 metric wrenches (6, 8, 10, 12, 13, 14, 15, 16, 17, and 18 mm). Both standards are covered in a single set.
Yes. Kobalt brand hand tools carry a lifetime warranty honored through Lowe's stores. Community evidence confirms the warranty has been honored at the brand level for hand tools generally; ASIN-specific warranty claim reports for this exact model are not documented in the available evidence base.
A ratchet wrench set (this product) uses combination wrenches with a ratcheting box end · one end is an open-end wrench, the other is a 12-point ratcheting box end. The wrenches are fixed to a specific size and do not use interchangeable sockets. A socket ratchet set uses a ratchet handle with interchangeable sockets on a drive square (1/4, 3/8, or 1/2 inch). Both use a ratcheting mechanism, but they serve different tasks.
No. Extension bars are not part of a combination ratchet wrench set · this product format does not use socket drive extensions. The set includes 20 combination ratchet wrenches and a rail-style molded holder.
