From curved cuts in solid timber to clean cross-cuts in chipboard and composites, the Bosch GST 18V-125 S Professional delivers corded-class performance without the cable. Its barrel-grip design gives you precise control close to the cut line, while 4-stage orbital action lets you dial between fast material removal and a clean finish — body only, ready for your existing 18V AMPShare batteries.

Key Features

• Brushless motor — corded-class performance with longer runtime per charge and extended motor life
• 4-stage orbital action — select between aggressive fast cutting or fine, clean cutting to suit the material
• Variable speed (500–3,500 spm) — dial in the right stroke rate for different materials and applications
• Barrel-grip design — low-profile grip for close-to-the-cut-line control and precision on curved work
• ±45° bevel baseplate — adjustable for angled and bevel cuts without a secondary tool
• Tool-free Bosch SDS blade change — fast, safe blade swaps with no tools required
• Removable plastic overshoe — protects sensitive or finished workpiece surfaces from scratching
