Kobalt KIW4024A-03 24V Mid-Torque Impact Wrench Review: Big Performance for Less

Introduction

Kobalt has entered the mid-torque impact wrench market with the KIW4024A-03, part of its 24V line. It is not XTR, Kobalt’s top tier, but the advertised numbers look like they belong there: 650 ft-lbs of nut-busting torque and 500 ft-lbs of fastening torque. That is essentially the same output as Kobalt’s most powerful non-XTR impact, which is a much larger tool.

The real hook is the price. At $229 as a kit, it includes a 4Ah extended-run battery and a 150W fast charger, putting its total cost close to what many competitors charge for the bare tool alone. After putting it through a full round of bolt-testing, it earned a strong mid-torque ranking result, finishing fourth and ahead of the Milwaukee and Makita on value-adjusted points.

Who This Impact Wrench Is For

This is a tool for anyone who wants serious mid-torque output without paying premium bare-tool prices. It is especially relevant if you are already in the Kobalt 24V battery family, since the kit price makes it one of the best-value additions to that platform. It also suits homeowners and light-trade users who work on vehicles, suspensions, or heavy fasteners occasionally rather than daily.

Performance in Testing

In forward-threaded bolt tests, the Kobalt topped a direct comparison against the Milwaukee 2962 and the Makita XWT17Z, putting up a 366 ft-lbs result in a five-second working test. In the 15-second best-case scenario test, it recorded 461 ft-lbs with the included battery and 433 ft-lbs with the XTR-style pack, slotting right between the Milwaukee and Makita. Its highest forward peak of the day was 486 ft-lbs.

Reverse performance was more ordinary: 412 ft-lbs in the 10-second reverse test, right in the middle of the pack compared to 427 and 385 from the two competitors. Against its 500 ft-lbs claim, the tool met 97 percent of its rated figure across forward and reverse threaded bolts, which is consistent with what we have historically seen from Chervon-built brands like Kobalt, Flex, and Ego: ratings that are close to or even underrated versus reality.

One thing worth noting: during several runs, the tool felt unstressed, almost under-driven, even in mode 3 with Auto off, which the manual confirms is its top power range. That composure is part of why it does not feel like it is being wrung out to hit its numbers.

Size, Weight, and Design

At 6.8 inches long, the Kobalt sits where most mid-torques do today, with the Milwaukee 2962 being the compact exception at six inches and 0.9 pounds lighter with a battery attached. The Kobalt is a chunkier tool, and its rubber nose cover and overall bulk draw clear aesthetic comparison to the Makita mid-torque, which measures a similar 6.7 inches. That thicker, more substantial route to high performance has become popular lately, and this tool fits the pattern.

Battery Choice Matters

The included 4Ah extended-run battery delivers noticeably better results than the standard 2Ah Kobalt pack. In back-to-back testing, the 2Ah produced a 397 ft-lbs peak, under what the tool managed in a shorter test with the extended-run battery, and the tool audibly and physically trails off when work gets tough. Kobalt is clearly one of those brands with a dramatic gap between regular and small packs, likely to keep battery costs down, which they do reasonably well.

Pairing the tool with the XTR-style 4Ah 21700-cell pack also shaves some bulk, making it feel a little less like you are swinging a medieval mace.

Value and Ranking

On the ranking list, the Kobalt scored 37, 41, and 48 points across categories, all solid numbers for a mid-torque. Its 6.8-inch length works out to 71.5 ft-lbs per inch. The price gets an asterisk for now because it is only sold as a kit; once a bare tool is available, that will change. As scored, it totals 338.6 points, placing it fourth overall, above the Makita and Milwaukee, and just below the Metabo HPT, which uses a similar kit-first strategy.

Buying Advice

For $229 with a battery and fast charger included, this is one of the strongest value propositions in the mid-torque category. It may not be the rumored second coming, but it brings Milwaukee-and-Makita-adjacent power to a price point where those brands sell bare tools only. Given that this is Kobalt’s standard 24V line and not XTR, it also raises the question of what Chervon could deliver at a dedicated XTR mid-torque price point.

If you need the most compact option, the Milwaukee 2962 remains the size and weight pick, and the Makita XWT17Z is the established alternative. But if value per pound of torque is the priority, the Kobalt is easy to recommend.

Conclusion

The KIW4024A-03 is arguably the best impact wrench Kobalt currently makes, including the XTR, given how much size and weight the XTR needs to achieve its output. It delivers class-competitive torque, meets nearly all of its claims, and does so in a kit configuration that costs less than most rivals’ bare tools. For Kobalt 24V users and value-focused buyers alike, it is a genuinely compelling mid-torque option.
