This kit provides all-day runtime with up to 15+ hours using an M12 REDLITHIUM 3.0 CP battery. The high-intensity green laser provides superior visibility up to 125 ft, or 165 ft when used with a detector. Accuracy is rated at ±1/8 inch at 33 ft. The cross-line laser projects both vertical and horizontal lines simultaneously, while four plumb points enable quick floor-to-ceiling transfers and squaring applications. The integrated magnetic bracket features micro-control that rotates around the vertical point for quick alignment. Amplified rare earth magnets provide a strong hold on steel studs without slipping. The tool has an IP54 rating for water and dust resistance.

For tile installers, cabinet makers, carpenters, general contractors, and DIY home renovators. Common uses include installing floor and wall tiles, hanging kitchen cabinets, mounting picture frames, aligning electrical outlets, installing chair rails, and installing drop ceilings.

This kit includes one M12 REDLITHIUM 3.0 CP battery pack and one M12 lithium-ion battery charger. The device provides up to 15+ hours of continuous operation on a single charge. As part of the Milwaukee M12 system, this laser level is compatible with all M12 batteries, allowing users to swap in any existing M12 battery pack for extended work sessions. The kit also includes a responsive laser alignment target for improved visibility in bright conditions, and a hard plastic carrying case for transportation and storage.
