Bosch Power Tools is often revered as a world market leader for power tools and accessories, and recently they announced the addition of two new Green-Beam Self-Leveling Cross-Line Lasers to their lineup: the GLL100-40G and the GCL100-40G with Plumb Points. These new tools use green-beam technology to emit vibrant green lines and points that are 4X brighter and more visible to the human eye than standard red beams—even in direct sunlight. Designed for Bosch Power Tools North America in their Illinois headquarters, the lasers are available now at Ohio Power Tool.

Bosch-exclusive VisiMax™ technology monitors tool temperature and power consumption to deliver the brightest lines for the job. These lasers automatically optimize the line visibility and brightness to help prevent the tool from overheating while maximizing the battery life and extending runtime on the jobsite. Like all Bosch tools, the GLL100-40G and GCL100-40G are engineered to be jobsite tough, withstanding rainy or dusty jobsite conditions and IP64 rated. Deeply recessed laser glass windows help ensure the tools are protected, and they are also equipped with a full overmold rubber housing that works like a roll cage to protect every major impact point.

“After months of market research and hands-on input from trade professionals, the new Bosch cross-line lasers are brighter, smarter and tougher than leading competitors. Next-level durability and green-line visibility coupled with technology that gives several more hours of on-the-job-battery life make these lasers a must-have tool for any worksite.”  

Brandon Eble, Group Product Manager at Robert Bosch Tool Corporation NA

The GLL100-40G features a rugged new mounting bracket with extra strong magnets for rapid setup, while the GCL100-40G allows for additional applications with 50 ft. upward and downward plumb points and the tough RM10 Rotating Mount with a rotation nob for making fine adjustments on the fly.

The bright green beams on the new GLL100-40G and GCL100-40G lasers can be projected vertically, horizontally or in a cross-line mode for pinpoint accuracy. The Smart Pendulum System allows the tools to self-level and indicate an out-of-level condition. With the press of a button, you can control the laser output so that lines can be seen separately or together. This feature creates the opportunity for a wide array of alignment and leveling applications, making them perfect for carpentry, cabinetry, concrete, electrical, drywall, framing, roofing, plumbing, HVAC and more.
