The Bosch Professional GST 18 V-LI B Cordless Jigsaw is a high-performance power tool designed for professional tradespeople and serious DIY enthusiasts. Here’s a detailed review covering its features, advantages, and potential drawbacks:
Key Features:
Cordless Power: As part of the Bosch Professional 18V System, the GST 18 V-LI B runs on Bosch’s 18V lithium-ion batteries. This offers the freedom to work anywhere without being tethered to a power cord, providing flexibility on the job site.
Compact and Lightweight: Weighing only 2.4 kg (including battery), it is designed to be easily portable and comfortable to handle for extended periods. Its compact design also helps when working in tight spaces.
Pendulum Action: The jigsaw comes with an adjustable 4-stage pendulum action, allowing for faster, aggressive cuts or smoother, more precise ones, depending on the material and the user's needs.
Tool-Free Blade Change: The SDS system allows for quick and easy blade changes without the need for extra tools, reducing downtime during work.
Cutting Depth: It can cut up to 120mm in wood, 20mm in aluminum, and 8mm in metal, making it highly versatile across a range of materials.
Variable Speed: Equipped with variable speed control, users can adjust the speed of the jigsaw to suit the material and type of cut, enhancing accuracy and control.
Dust Extraction: The jigsaw has a built-in connection for dust extraction, helping to keep the work area clean and improve visibility along the cutting line.
LED Light: The tool features an LED light to illuminate the cutting line, which is particularly useful when working in low-light conditions.
Pros:
Excellent Performance: With its powerful 18V motor and adjustable speed, the jigsaw offers excellent cutting performance in various materials, from wood to metal.
Battery Compatibility: Being part of Bosch's Professional 18V system, the jigsaw can share batteries with other tools in the range, making it convenient for users already invested in Bosch’s ecosystem.
Easy Blade Changes: The SDS blade system is a standout feature, enabling fast and hassle-free blade swaps during jobs, saving time and effort.
Durability and Build Quality: Like most Bosch tools, the GST 18 V-LI B is built to withstand tough job site conditions, with a robust design and high-quality components.
Good Ergonomics: Its lightweight and well-balanced design, along with the soft-grip handle, ensures comfort during prolonged use, reducing hand fatigue.
Cons:
Battery Life: The jigsaw’s power-hungry motor can drain batteries relatively quickly, especially when cutting thicker or denser materials. It’s advisable to have extra batteries on hand for longer tasks.
Price: As a professional-grade tool, it comes with a higher price tag than entry-level models. However, this is justified by its performance and durability.
No Batteries Included: Often sold as a “bare tool” (without batteries or charger), this could be a drawback if you don’t already have compatible Bosch 18V batteries.
Limited Features for Precision: While it does have variable speed and a pendulum function, it lacks some of the advanced precision features found in high-end jigsaws, such as an integrated laser guide.
Overall Verdict:
The Bosch Professional GST 18 V-LI B Cordless Jigsaw is an excellent choice for professionals and serious DIYers looking for portability, power, and durability in a jigsaw. Its cordless design offers great flexibility, and the tool-free blade change system enhances its ease of use. The adjustable pendulum action and variable speed control provide versatility for various cutting tasks, whether in wood, metal, or other materials.
While it comes at a premium price, especially considering that batteries are often sold separately, the performance, build quality, and compatibility with the broader Bosch 18V range make it a worthy investment for those who need a reliable, high-quality cordless jigsaw.
