M12™ Green Cross Line & Plumb Points Laser Kit

The Milwaukee M12™ Green Cross Line & Plumb Points Laser (model 3622-21) is a cordless self-leveling laser that projects a horizontal and vertical green cross line plus two plumb points for fast floor-to-ceiling layout. As a “-21” kit it runs on the M12™ battery system and ships with an M12™ REDLITHIUM™ battery and charger. The high-intensity green beam is optimized for distance, with a 125 ft working range and up to 165 ft range when paired with a detector.

What it does well

• Green cross line (horizontal & vertical) plus two plumb dots for quick transfers from floor to ceiling
• Bright green laser optimized for distance — 125 ft working range, 165 ft with a detector
• Self-leveling within ±4° tilt, accurate to ±1/8" at 33 ft
• Integrated magnetic bracket with amplified rare earth magnets that hold on steel studs without sliding; micro-control pivots on the plumb point, plus a hang hole and 2" plumb point access

Is this the right laser for you?

Choose this laser if you work interior layout — walls, drops, fixtures, framing — and want a green beam that stays visible at range in bright conditions. It fits crews already on the M12™ platform who want one battery system across their tools, and the IP54 rating plus 1m impact resistance suit it to real jobsite handling. If you only need a single line or work exclusively outdoors at long distance, compare against dedicated rotary or line-specific models.
