Milwaukee M12™ Green Cross Line & 4-Points Laser Kit
Product Overview
The Milwaukee M12™ Green Cross Line & 4-Points Laser Kit (3624-21) is a cordless layout laser designed to simplify leveling, alignment, plumbing, and squaring tasks on the jobsite. It combines bright green horizontal and vertical laser lines with four additional points, giving users multiple reference points for common construction and installation applications.
Powered by the M12™ REDLITHIUM™ CP 3.0 battery, the laser provides 9+ hours of continuous runtime according to Milwaukee. Its high-intensity green beam is designed for visibility at distances up to 125 feet, while a compatible detector can extend the working range to 165 feet.
The 3624-21 kit includes the laser, M12 3.0 Compact Battery Pack, M12 charger, responsive laser alignment target, and carrying case, providing a complete setup for users who need a ready-to-use cordless laser layout solution.

Bright Green Cross-Line Projection
The high-intensity green laser is optimized for visibility and long-range layout work. The horizontal and vertical lines create a cross reference that can be used for leveling and alignment, making it easier to establish accurate reference lines during installation and construction.
The laser has a 125-foot working range, while use with a compatible detector extends the stated range to 165 feet.
Four-Point Layout
In addition to the cross lines, the laser produces four points that expand its usefulness for layout work. The points can assist with floor-to-ceiling transfers and squaring applications, helping users establish reference locations without relying solely on traditional measuring methods.
The 2-inch plumb point access further supports point-transfer applications where a reference needs to be carried through or around a mounting surface.
Micro-Control Adjustment
The integrated magnetic bracket incorporates micro-control adjustment and pivots around the plumb point. This design allows users to make fine alignment corrections after the laser has been positioned, reducing the need to repeatedly move the entire unit.
Secure Magnetic Mounting
Amplified rare-earth magnets provide a strong hold on suitable metal surfaces and are designed not to slide on steel studs. An integrated hang hole provides another convenient mounting option when magnetic attachment is not suitable.
The laser also includes 1/4"-20 and 5/8"-11 threaded mounts, allowing it to be used with compatible mounting hardware and tripods.
Self-Leveling Performance
The laser is designed to self-level within ±4° of tilt. Its specified accuracy is ±1/8 inch at 33 feet, providing a practical reference for professional layout and installation work.
Jobsite Durability
The Milwaukee M12 Green Cross Line & 4-Points Laser carries an IP54 rating, providing protection against dust and water exposure under the conditions defined by the rating. It is also rated for 1-meter impact resistance, helping it withstand the bumps and drops that can occur during normal jobsite use.
Battery and Runtime
The kit includes an M12™ REDLITHIUM™ CP 3.0 Compact Battery Pack (48-11-2430). Milwaukee rates the laser for 9+ hours of continuous runtime when using this battery.
Because the laser is part of the M12™ System, it is also compatible with all M12 batteries, providing flexibility for users who already own other M12 tools and batteries.
