Zaag Bosch GKM 18V-50 Professional

The Bosch GKM 18V-50 Professional is a cordless metal circular saw designed for fast, precise cutting of ferrous materials. It combines a compact form factor with features that support clear visibility of the cut and reduced spark generation, and is compatible with the Bosch Professional 18 V battery system.

Advantages

The tool delivers nearly spark-free operation thanks to an integrated, robust chip collection box with an easy-open door for quick emptying. A cutting-line indicator, viewing window and integrated LED light provide a shadow-free view for accurate cuts. An ergonomically optimised grip improves handling and reduces user fatigue during extended use. The saw is supplied with a saw hook and a blade optimised for cutting steel to enhance cordless runtime.

How to use

Fit a charged Bosch Professional 18 V battery and ensure the blade is the correct type and securely mounted. Mark the cutting line and align the cutting-line indicator and viewing window for a clear sightline. Switch on the saw and let it reach full speed before engaging the material; feed the saw steadily and avoid forcing it to maintain precise cuts. After cutting, allow the blade to stop completely before setting the tool down and open the chip collection box to empty collected debris.

Recommendations

Use the supplied steel-optimised blade for best battery runtime and cutting performance on ferrous materials; wear appropriate personal protective equipment and follow Bosch safety instructions for metal cutting and battery-powered tools.
