About Rotation Laser PRO GRL 350 HV Bosch

The Bosch GRL 350 HV is a self-levelling rotation laser tool designed for precise horizontal and vertical levelling, alignment and grading on construction sites and large-scale layout work. It projects a 360 rotating laser beam to create high-visibility reference planes that help with excavation, formwork, foundations, and general site grading.

Key Features

• Rotational laser for horizontal & vertical use  Ideal for dual-axis levelling tasks.

• Manual dual slope control  Enables grade adjustments in two axes for sloping surfaces.

• Variable rotation speed & scan-angle settings  Helps optimize visibility in different jobsite lighting.

• Robust build (IP56 rating)  Dust- and splash-proof for tough environments.

• Shock warning feature  Alerts if the instrument vibrates or is disturbed, helping maintain accuracy.
