Bosch Professional 18V System Cordless Jigsaw GST 18V-125 S vs Bosch Professional Corded Jigsaw GST 150 BCE

Power Source & Portability

The Bosch Professional 18V System Cordless Jigsaw GST 18V-125 S offers complete freedom from power cables, making it ideal for jobs where access to electricity is limited. In contrast, the Bosch Professional Corded Jigsaw GST 150 BCE requires a fixed power source, limiting mobility but ensuring consistent energy delivery. The cordless model’s 18V system allows for uninterrupted use on-site, while the corded version relies on a 240V connection. This fundamental difference makes the GST 18V-125 S significantly more portable and versatile in diverse working environments.

Motor Performance & Cutting Capability

The GST 150 BCE features a robust 780 W motor with constant speed control, designed for demanding tasks such as cutting thick beams or dense materials. Its powerful performance ensures steady operation under load. Meanwhile, the GST 18V-125 S utilises a brushless motor, which delivers high efficiency and longer runtime without sacrificing power. While the exact wattage isn’t provided, the brushless design typically translates to better torque and reduced heat build-up compared to standard motors. Both tools are built for heavy-duty work, but the corded model has a clear edge in raw power output.

Cut Precision & Versatility

Both jigsaws offer advanced features for precision cuts. The GST 18V-125 S includes a 4-stage orbital action that allows users to switch between fast cutting and clean, splinter-free results depending on the material. It also features Speed Selection for optimal performance across different substrates. The GST 150 BCE lacks an orbital action setting but compensates with a bend-resistant, robust sole plate that maintains stability during deep or aggressive cuts. The GST 18V-125 S is better suited for intricate curved and section cuts, while the GST 150 BCE excels in straight, high-stress applications due to its durable construction.

Ergonomics & Handling

The GST 150 BCE features a barrel grip design that enhances control, particularly when working overhead or in tight spaces. This ergonomic shape supports smooth handling even during extended use. The GST 18V-125 S, while not explicitly described with a barrel grip, benefits from its cordless nature, reducing cable drag and improving balance during manoeuvring. Both models include an anti-splinter guard and dust extraction systems, contributing to safer, cleaner operation. The GST 150 BCE’s design prioritises strength and comfort for continuous industrial use, whereas the GST 18V-125 S focuses on lightweight agility.

Included Accessories & Value

The GST 18V-125 S comes with one jigsaw blade (T 144 D, Speed for Wood), a dust extraction set, and an anti-splinter guard—ready for immediate use. The GST 150 BCE includes a similar range: one blade (T 144 DP, Precision for Wood), dust extraction set, glide shoe, hood, suction nozzle, and anti-splinter guard. Both tools provide comprehensive starting kits. However, the GST 18V-125 S is priced at £109.98, about 35% cheaper than the GST 150 BCE at £169.99. This represents a significant saving, especially considering both are professional-grade tools with strong accessory packages.

Price & Market Positioning

The GST 18V-125 S is priced at £109.98, undercutting the GST 150 BCE by £60.01—approximately 35% less. Despite this price advantage, the GST 18V-125 S holds a bestseller rank of 35, indicating strong consumer demand. The GST 150 BCE ranks 45, slightly lower, though still well-regarded. The lower price point of the cordless model suggests greater accessibility without compromising core functionality. For professionals seeking cost-effective yet reliable performance, the GST 18V-125 S offers superior value per pound spent.

Which should you buy?

Choose the Bosch Professional 18V System Cordless Jigsaw GST 18V-125 S if portability, versatility, and cost savings are priorities—especially for on-site work, curved cuts, or frequent repositioning. It’s about 35% cheaper than the GST 150 BCE at £109.98, offering excellent value with a brushless motor and 4-stage orbital action. Opt for the Bosch Professional Corded Jigsaw GST 150 BCE only if you require maximum continuous power and don’t need mobility—ideal for workshop-based projects involving thick or hard materials, where a stable 240V supply is available.
