Bosch GST 18V-125 S Cordless Jigsaw 18V Brushless, regulator, bare tool

The Bosch GST 18V‑125 S jigsaw is an 18V cordless tool with a brushless motor, 26mm blade stroke, 4-position pendulum action, and a ±45° tiltable base. It is supplied as body only in a cardboard box version, without batteries or charger.

The Bosch GST 18V‑125 S Professional (code 06015B2000) is designed for professionals who need a powerful, versatile jigsaw that is fully compatible with the Bosch 18V system. The brushless motor ensures high cutting performance on solid wood, panels, composite materials, and harder materials.

Thanks to the 4-stage pendulum action, you can choose between a faster or cleaner cut, adapting the cutting action to the material. The speed selector allows you to adjust the stroke frequency (500-3,500 spm) depending on the job to be done.

The saw's base can be tilted up to ±45°, for precise bevel and miter cuts. The Bosch SDS system allows for quick and tool-free blade changes. The design also includes a splinter guard to protect the workpiece.

Weighing 1.9 kg without battery, it is light enough for prolonged use, while maintaining excellent stability. Your "body only, cardboard" version is perfect if you already own Bosch 18V batteries and want to save on packaging.

This jigsaw is an excellent cost/quality addition for those who already have Bosch Professional system batteries. The aluminum base is perfect for intensive work, and its handling makes it ideal for both construction sites and workshops.
