Bosch Professional GTL 3 Tile Laser

The Bosch Professional GTL 3 Tile Laser is a precision alignment tool for installing wall and floor tiles. It projects reference lines to guide the placement of ceramic tiles, clinker, and other flooring materials. It maintains an accuracy of 0.2 mm/m across a working range of up to 20 m, which is enough to establish consistent indoor layouts without manual marking. A visible beam projects from the optical system for clear visual tracking during installation.

An IP54 rating protects the housing against dust and water splashes common on construction sites. Power is supplied by four AA batteries, providing up to 18 hours of continuous operation. Four batteries are included, so the tool is ready for immediate use out of the box. A target card is also provided to improve line visibility at the upper end of the working range. The exterior has a black and blue finish designed to withstand typical job site conditions.
