Reciprocating saw Bosch GSA 120 06016B1020

Power and performance in demanding conditions

The 1200 W motor is the heart of this reciprocating saw, allowing for the cutting of thick materials without the need for excessive pressure. Thanks to this, the tool handles hard construction timber, metal pipes, or steel sheet metal, maintaining a constant speed even under full load. The Constant Electronic system ensures that the stroke rate does not drop upon contact with the material – which is crucial for tasks requiring precision and uniform cutting. Smooth speed regulation in the range from 0 to 3000 rpm provides full control over the processing, whether you are working with soft plastics or thick steel.

A stroke length of 29 mm translates directly into the speed of work progress. The larger the stroke, the fewer cycles are needed to cut through a given element. In practice, this means the GSA 120 saw can cut wood up to 220 mm thick or metal pipes and profiles with a diameter of up to 220 mm in just a few strokes. In the case of thin steel sheet metal, the cutting depth is 20 mm, which is sufficient for most assembly and disassembly tasks in construction or industry.

Ergonomics and structural durability

Despite its high power, the device weighs only 3.7 kg, making it easier to work overhead or in hard-to-reach places. The housing has been designed to distribute the tool's weight evenly across the operator's hands. The Softgrip coating on the handle not only improves grip comfort but also significantly reduces vibrations transmitted to the wrist – which is important during longer work sessions. The new gear arrangement features a low friction coefficient and an optimized heat dissipation system, resulting in an extended service life of the mechanism even under extreme operating conditions.

Blade replacement is fast and tool-free thanks to the SDS (Bosch) system. This mechanism allows for changing a worn blade with one hand in a matter of seconds, minimizing downtime. An additional advantage is the adjustable cutting depth limiter and the rubber-covered front grip, which ensures stability while guiding the saw along the material surface. The long 3 meter power cord increases the operating range without the need for constant use of extension cords.

Application and scope of delivery

This saw is ideal for renovation, demolition, and gardening work. Its versatility allows for cutting:

• Solid wood and chipboards
• Steel pipes and aluminum profiles
• Plastics (PVC)
• Gypsum and aerated concrete
• Ceramic brick (depending on the blade type)

The set includes one S 1126 BEF Heavy for Metal blade designed for cutting metals with wall thicknesses from 3 to 8 mm (e.g., pipes and profiles). The tool is delivered in a cardboard box along with a hex key necessary for any service adjustments and an instruction manual. The noise level generated during operation is approximately 88.5 dB(A), and the vibration level is effectively dampened by the design of the ball-bearing oscillating mechanism.

It is worth remembering the basic features of this model: the nominal power of the device is 1200 W, and the stroke rate can be smoothly adjusted in the range from 0 to 3000 min⁻¹. The blade stroke length is 29 mm, allowing for a cutting depth of 220 mm in wood and metal pipes (at a maximum diameter of 220 mm) or 20 mm in steel sheet metal. The entire device weighs 3.7 kg and has a power cord length of 3 m. The sound pressure level during operation oscillates around 88.5 dB(A).
