With enhanced brightness and the longest working range offered in the market, Bosch’s green-beam laser goes farther for leveling and grading accuracy

Bosch Power Tools, a global leader for power tools and power tool accessories, adds to its robust line of grading and leveling solutions with the introduction of its 18V REVOLVE 4000 Connected Green-Beam Self-Leveling Rotary Laser (GRL4000-90CHVG). Providing users with a superior experience during a range of heavy-duty tasks, the new laser features higher visibility up to four-times brighter than traditional red beams, extended leveling range, and additional ADS settings, ideal for varied work sites. The 18V REVOLVE 4000 offers users the additional accuracy, precision, and customization to get the job done right.

“Our goal was to design a laser that could adapt to any jobsite condition, ensuring that professionals working on projects ranging from landscaping to framing and anything in between can have the leveling flexibility they need all in one product,” said Brooke Corbin, Product Manager for Bosch Power Tools. “This new green-beam laser is setting a high bar for other tools in this sector with its 4,000-foot measurement range, Dual axis Dial-In Slope and its easy user calibration (uCAL) capabilities, allowing for advanced real-time precision adjustments while on the job.”

Features and Benefits

The 18V REVOLVE 4000 elevates the user experience with the addition of a wide range of new features to ensure the laser is properly setup for internal and external projects. With its comprehensive display, professionals can easily adjust the tool to fit their real-time needs.

  • Slope Memory Data Storage: In addition to its durable design, the laser offers an added level of convenience with its slope memory feature that saves slope entry profiles on the tool for up to four entries.

  • Bluetooth® Connectivity: Connectivity to the Bosch Leveling Remote App is just a click away with the added Bluetooth® features, simplifying laser control and minimizing disturbances to the laser level during the workday.
