Milwaukee M12™ Green Beam Laser Kit – Cross Line & Plumb Points
Product Overview
The Milwaukee M12™ Green Cross Line & Plumb Points Laser Kit (3622-21) is a cordless laser layout solution designed for accurate leveling, alignment, and point-transfer work. It combines high-intensity green horizontal and vertical laser lines with two plumb points, giving professionals a versatile reference tool for construction and installation applications.
The green beam is designed for visibility at distances of up to 125 feet, with the range extending to 165 feet when used with a compatible detector. Milwaukee rates the laser at ±1/8 inch accuracy at 33 feet and provides self-leveling within ±4° of tilt.
As a complete kit, the 3622-21 includes the laser, an M12 REDLITHIUM™ 3.0Ah CP battery, charger, laser target, and carrying case, providing the essential components needed to get started without purchasing the battery and charger separately.

High-Visibility Green Beam
The high-intensity green laser is optimized for long-distance visibility, making it easier to establish reference lines during interior construction and installation work. The horizontal and vertical lines can be used individually or together to create a cross-line reference for leveling and alignment.
The laser provides a stated 125-foot working range, while a compatible detector can extend the range to 165 feet.
Cross-Line Projection
The horizontal and vertical laser lines provide a convenient reference for establishing level and plumb lines. This makes the laser useful for positioning walls, cabinets, fixtures, framing components, electrical installations, and other items that need consistent alignment.
The cross-line capability also reduces the need for repeated manual measurements when transferring a straight reference across a work area.
Two Plumb Points
Two dedicated plumb points expand the laser's capabilities beyond conventional cross-line leveling. They provide reference points above and below the laser, making floor-to-ceiling transfers and vertical alignment tasks faster and easier.
This feature is particularly useful when installing items that need to remain vertically aligned between different elevations.
Micro-Control Adjustment
The integrated magnetic bracket features a micro-control mechanism that pivots on the plumb point. This allows users to make fine alignment adjustments without having to repeatedly reposition the entire laser.
The design is useful when precise positioning is required across longer distances or when establishing an exact reference line.
Secure Magnetic Mounting
Amplified rare-earth magnets provide strong attachment to suitable metal surfaces and are designed not to slide on steel studs. The integrated bracket also includes screw and nail hang holes, giving users alternative ways to position the laser when magnetic mounting is not practical.
Self-Leveling Accuracy
The laser automatically self-levels within ±4° of tilt, helping users establish reliable horizontal and vertical references without manually leveling the tool.
Milwaukee specifies an accuracy of ±1/8 inch at 33 feet, making the laser suitable for a wide variety of professional layout applications.
Long Runtime with M12 Power
The 3622-21 kit includes an M12 REDLITHIUM™ 3.0Ah CP battery. Milwaukee states that the laser can provide more than 15 hours of continuous runtime when used with an M12 3.0 CP battery.
Because the laser is part of the M12 system, users can also power it with other compatible M12 batteries.
Jobsite Durability
The laser features an IP54 rating, providing protection against dust and water exposure within the limits of the rating. It also carries a 1-meter impact-resistance rating, helping it withstand the bumps and impacts associated with normal jobsite use.
