Bosch Professional 12V System GOP 12V-28 cordless multi tool with Starlock tool holder (incl. Starlock BIM plunge-cut saw blade)
Product description
The essentials
If you’re building out a compact cordless kit, the Bosch Professional 12V System GOP 12V-28 multi tool approach makes sense on paper: it’s part of Bosch’s Starlock ecosystem, aimed at getting tools swapped quickly while keeping power transfer efficient. It also comes with one Starlock BIM plunge cut saw blade for wood + metal, so you’re not starting from a blank slate.
That said, there’s an important catch to keep in mind: this bundle is “without battery/charger”. On the upside, that lets you match it with the batteries you already own (if you’re in that same platform). On the downside, if you’re buying from scratch, the overall spend can jump once you factor in power source.

A quick practical example: you’re trimming a section of skirting or cutting through a mixed material offcut during a small refurbishment. With a plunge-cut blade in place, you can start a cut without needing perfect access from the edge—handy when space is tight and you want to get the job done without fuss.
What matters most in everyday use
What stands out from the description is the way Bosch frames the ergonomics and connection system. The handle grip is described as the smallest in the Starlock category, with the goal of making it easier to operate for longer stretches. For smaller jobs and frequent handling, that kind of “feel” can matter more than big performance claims.



The Starlock interface is also pitched as a 3-dimensional tight connection designed for direct power transfer. In real terms, that’s the sort of design choice you tend to notice as better responsiveness when you’re guiding the tool—especially on detail work or when you’re switching between materials.
Key features (and the bits you’ll actually notice)
You’re getting a Bosch Professional 12V System cordless multi tool body (GOP 12V-28) paired with a Starlock tool holder, plus a single blade:

- Included blade: 1× Starlock BIM plunge cut saw blade AIZ 32 APB, Wood + Metal, with Curved-Tec.
- Blade packaging: supplied in a cardboard box.
- Design focus: Bosch describes it as the most compact cordless multi tool in its Starlock category.
The “Curved-Tec” blade detail suggests the blade is shaped for more effective cutting performance, but the description doesn’t give more specifics (so it’s sensible to treat it as a useful design element rather than a guarantee of a certain outcome on every material).
Also, being lightweight is mentioned for comfort and convenience. That’s usually a good sign if you plan to do overhead or awkward-angle work—where fatigue is often the real limiting factor.



Where it shines (and where it may fall short)
This is best thought of as a compact, multi-purpose cordless tool for regular DIY and light trade jobs where you want flexibility. If you already own Bosch 12V batteries, it can slot neatly into your kit with minimal disruption.
It may not be the best match if you’re expecting a complete “ready to use” purchase. Since it’s without battery and charger, you’ll need to confirm your existing ecosystem—or budget for the power source.

Also, because the scope of supply lists only one plunge-cut blade, you may still want to add other blade types for different tasks. Multi tools live or die by accessories, so if your plan involves a wide variety of materials and cuts, it’s worth checking what else you’ll likely need.

Should you buy it?
It makes sense if you want a compact Starlock-compatible cordless multi tool for frequent small-to-medium jobs, and you either already have Bosch 12V batteries or you’re comfortable sourcing them separately. The included BIM plunge-cut blade for wood + metal is a practical starting point, and the focus on tight Starlock connection plus an ergonomic grip could make it pleasant for day-to-day handling.
You may want to skip it if you’re buying your first multi tool and need a complete kit in one go. Since it’s without battery/charger and includes only one blade, it can be less “grab-and-go” than alternatives sold as full sets.
