Saw Bosch GSA 18V-LI Professional

The Bosch GSA 18V-LI Professional cordless reciprocating saw delivers strong cutting performance and long runtimes for a variety of jobsite tasks. Powered by an 18 V lithium-ion battery, the saw achieves over 100 cuts into spruce beams sized up to 100 x 100 mm on a single charge. Built-in Electronic Motor Protection helps ensure durability and a long service life, while the tool-free Bosch SDS blade-change system speeds up blade replacement. The saw is compatible with all Bosch Professional 18 V batteries and chargers.

Advantages

Compact and lightweight at approximately 3.2 kg, the GSA 18V-LI Professional offers two-speed operation with stroke rates up to 2,700 spm, a 28 mm stroke length, and robust protection against deep discharge, overheating and overload. It delivers high cutting depth for wood and reliable performance on metal and plastics. The tool-free SDS system enables fast blade changes without additional tools, and Electronic Motor Protection increases motor lifetime under demanding conditions.

How to use

Install the appropriate reciprocating saw blade using the Bosch SDS tool-free system and ensure the blade is securely seated. Select the required gear (low or high stroke rate) according to the material and cutting speed needed. Hold the saw with both hands, position the blade on the cut line, and start cutting with steady forward pressure—let the saw do the work. Monitor battery charge level and change or recharge the 18 V battery as needed. Follow all safety instructions in the Bosch user manual and wear suitable personal protective equipment.

Usage recommendations

Use blades specified for the material (wood, metal, plastic) to achieve optimal cutting speed and blade life. For repetitive heavy cuts in timber, check battery capacity and consider spare 18 V batteries to maintain workflow. Allow the motor to cool during prolonged heavy use to extend service life.
