This bundle pairs the Milwaukee 3697-22 M18 FUEL 1/2-in. Hammer Drill and 1/4-in. Hex Impact Driver Combo Kit with the Milwaukee 48-59-1862S M18 REDLITHIUM HIGH OUTPUT XC 6.0Ah Battery 2-Pack Starter Kit. You get the two core M18 FUEL tools plus enough battery capacity to keep both running all day. Model Numbers: 3697-22 (M18 FUEL hammer drill/driver and impact driver combo kit), 48-59-1862S (two HIGH OUTPUT XC 6.0Ah batteries and an M18/M12 charger).

The 3697-22 combines the M18 FUEL 1/2 inch hammer drill/driver (2904-20) with the M18 FUEL 1/4 inch hex impact driver (2953-20). The hammer drill is listed at 1,400 in-lbs of torque and 6.9 inches long. Its hammer mode handles brick, block, and concrete, and AutoStop control mode helps protect against over-rotation in a bind-up. The impact driver delivers up to 2,000 in-lbs and 3,900 RPM at 4.47 inches long, with 4-Mode Drive Control and single-handed bit insertion. The kit ships with two M18 REDLITHIUM XC5.0 batteries, an M18/M12 charger, a side handle, belt clips, and a blow molded case.

The 48-59-1862S adds two M18 REDLITHIUM HIGH OUTPUT XC 6.0Ah batteries (48-11-1865) and another 48-59-1812 M18/M12 charger. Milwaukee states these packs deliver 50% more power and run 50% cooler than M18 REDLITHIUM XC packs, with 60% more runtime than an M18 XC5.0 battery. They also provide more power in extreme cold below 0°F (-18°C). Each pack has an onboard fuel gauge, REDLINK Intelligence overload protection, a rubber overmold, and a water protection barrier. The charger has a listed charge time of 60 minutes.

Everything here runs on the Milwaukee M18 platform. The two extra HIGH OUTPUT packs support higher-draw M18 tools you may add later, and both chargers also handle M12 batteries.

This bundle fits contractors, remodelers, and service techs buying into M18 FUEL who want a deep battery rotation from day one. It also suits crews that run the drill and impact driver hard enough that two batteries run out before the day does.

The core M18 FUEL pair, with the battery depth to back it up

Two of Milwaukee's most-used tools plus four batteries means you rarely wait on a charger.

• Who it's for: Pros starting or rebuilding an M18 FUEL setup who want more than two batteries in rotation from day one.
• Why it stands out: The HIGH OUTPUT 6.0Ah packs add more power and runtime than the XC5.0 packs in the combo kit, and they carry over to higher-draw M18 tools later.
• Worth knowing: You get two identical 48-59-1812 chargers, one from each kit. The 50% power, 50% cooler, and 60% runtime figures apply only to the two HIGH OUTPUT 6.0Ah packs, not the XC5.0 packs in the combo kit.

• How many batteries and chargers come in this bundle? Four batteries (two XC5.0 and two HIGH OUTPUT XC 6.0Ah) and two M18/M12 multi-voltage chargers.
• What tools are included? An M18 FUEL 1/2 inch hammer drill/driver (2904-20) and an M18 FUEL 1/4 inch hex impact driver (2953-20).
• Do the chargers work with M12 batteries? Yes. Both included chargers charge M18 and M12 battery packs.
• Can the hammer drill be used for masonry? Yes. Milwaukee states the hammer drill mode is intended for drilling into brick, block, or concrete.
