Reciprocating Saw Bosch GSA 18V-24 Professional 18V cordless, tool only, blue/black

The Bosch GSA 18V-24 Professional is a cordless reciprocating saw designed for demolition, renovation and on-site cutting tasks. Supplied as a tool-only 18V unit (battery and charger not included), the saw features a compact, ergonomically shaped blue/black housing that enables comfortable one-handed operation in confined spaces. With a stroke rate suitable for cutting wood, metal and composite materials when fitted with the appropriate blades, the tool is intended to bring portability and ease of use to plumbing, construction and renovation work.

Advantages

The compact design and low weight improve manoeuvrability and reduce operator fatigue during extended use. Brushless motor technology and an efficient drive deliver consistent cutting performance and longer tool life. Key ergonomics include an anti-slip grip and an accessible blade-change mechanism that allows quick blade swaps without additional tools. Battery-powered operation provides freedom of movement at job sites without mains power or extension leads.

Suitable for

• Demolition and selective dismantling in renovation projects
• Cutting timber, plywood and wooden beams with appropriate wood blades
• Cutting metal pipes, profiles and sheet metal with bi-metal or metal-cutting blades
• Plumbing and HVAC tasks requiring portable, one-handed cutting
• On-site trimming and fitting of composite materials

How to use

Fit a blade appropriate to the material and fasten it according to the tool’s blade-change mechanism. Install a compatible 18 V battery and set the variable speed control to a suitable stroke rate for the workpiece. Position the shoe against the cutting surface to stabilise the tool, then apply steady, controlled pressure while cutting. Allow the blade to reach full speed before engaging the material and follow safe cutting practices: secure the workpiece, avoid pinch points and keep hands clear of the blade path. After use, remove the battery and store the saw and blades in a dry place.

Recommendations

Use blades specified for the target material and maintain a moderate cutting speed for blade longevity. For heavy-duty metal cutting choose bi-metal blades; for fast wood cutting choose aggressive-tooth wood blades. Regularly inspect blades for wear and replace when dull to maintain efficient, safe cutting. Always wear appropriate personal protective equipment such as eye protection, gloves and hearing protection when operating the tool.
