Bosch Multi-Tool Blade Compatibility
Bosch co-developed the Starlock blade system with Fein in 2016, making them one of the two most important brands in multi-tool blade compatibility. However, Bosch has sold oscillating multi-tools since well before Starlock existed, which means older and newer models use completely different blade systems. This guide covers every Bosch multi-tool and explains exactly which blades fit each one.
Quick Answer
Bosch multi-tools use the Starlock system. Bosch Starlock blades are backwards-compatible with OIS tools, and any Starlock, StarlockPlus, or StarlockMax blade fits Bosch multi-tools.
Bosch Multi-Tool Models and Blade Systems
Bosch’s multi-tool range splits cleanly into two eras: pre-2016 (OIS/Multi-X) and post-2016 (Starlock). If you’re buying a new Bosch multi-tool today, it will almost certainly be Starlock. But if you own an older PMF model, you’re on the legacy OIS system.
| Model | Type | Blade System | Accepts |
|---|---|---|---|
| GOP 12V-28 | Cordless 12V | Starlock | Starlock blades only |
| GOP 18V-28 | Cordless 18V | Starlock | Starlock blades only |
| GOP 18V-34 | Cordless 18V | StarlockPlus | Starlock + StarlockPlus |
| GOP 30-28 | Corded 300W | Starlock | Starlock blades only |
| GOP 40-30 | Corded 400W | StarlockPlus | Starlock + StarlockPlus |
| GOP 55-36 | Corded 550W | StarlockMax | Starlock + StarlockPlus + StarlockMax |
| PMF 180 E | Corded (pre-2016) | Multi-X / OIS | OIS blades, universal blades |
| PMF 220 CE | Corded (pre-2016) | Multi-X / OIS | OIS blades, universal blades |
| PMF 250 CES | Corded (pre-2016) | Multi-X / OIS | OIS blades, universal blades |
Which Blades Fit My Bosch Multi-Tool?
If you own a post-2016 GOP model, you need Starlock blades. The exact tier depends on your tool — a GOP 12V-28 takes standard Starlock only, while the flagship GOP 55-36 accepts all three Starlock tiers. The simplest rule: buy standard Starlock blades and they’ll work in any Bosch Starlock tool.
If you own a pre-2016 PMF model, you need OIS or universal-fit blades. The good news is that newer Starlock blades are backwards-compatible with OIS tools, so you can buy Starlock accessories and use them on your older Bosch — you’ll just attach them via the OIS clamp rather than the Starlock push-fit mechanism.

Common Questions About Bosch Multi-Tool Blades
Can I use my old PMF blades on a new GOP tool?
No. OIS blades from pre-2016 PMF models are not compatible with Starlock GOP tools. However, Starlock blades are backwards-compatible with OIS tools — so if you upgrade your tool, you’ll need new blades, but any new Starlock blades you buy will also work on your old PMF if you keep it.
What’s the difference between Bosch green and blue multi-tools?
Bosch green (DIY/home range) and Bosch blue (Professional range) both use the same Starlock blade system on current models. The blade compatibility is identical — the difference is in the tool’s build quality, power, and features, not the blade interface.
Can I use Fein blades on my Bosch?
Yes. Fein and Bosch co-developed Starlock, and all Fein Starlock blades are fully compatible with Bosch Starlock tools (and vice versa). This is one of the key advantages of the Starlock ecosystem — you get access to accessories from both brands.
