Bosch GOP40-30C: problems, parts and running costs
Checked: 2026-10-17
Summary
The main thing to know is accessory compatibility: the StarlockPlus mount will not take StarlockMax blades, which need the GOP55-36 instead. Owners report the tool running hot in long sessions and note the corded design as an inconvenience. It is a one-time buy whose only recurring costs are blades and sanding sheets; at about $219 from Acme Tools it is a fair mid-range corded multi-tool.
Common problems and fixes
- StarlockPlus mount rejects StarlockMax blades — the most important limitation; StarlockMax accessories need the GOP55-36. Plain Starlock and StarlockPlus blades fit, so check which family a blade is before buying. [1]
- Runs hot during extended use — some owners report it; there is no published fix, so work in shorter bursts on long cuts. [1]
- Corded only, no cordless variant — there is no battery version of this model, and some users find the cord inconvenient for certain applications. [1]
- Starlock, StarlockPlus and StarlockMax naming confuses buyers — the three names are easy to mix up; confirm the interface on the blade before purchase. [1]
- Only a 1-year warranty — shorter than some rivals; Bosch corded power tools carry 1 year from the date of purchase. [2]
- No independent lab test — no instrumented test of this exact model was found, so performance claims rest on Bosch’s specifications and scattered owner feedback. [1]
Parts and consumables
Yearly running cost
Not enough data. The tool is corded, so there is no battery, charger, filter or subscription to budget for. The only recurring spend is blades and sanding sheets, and no store prices for them were found. [1][2]
When it is a good buy
Acme Tools listed the 32-piece kit at $219.00, marked down from $275.00, and ToolGuyd listed the kit at $199 in 2017. At about $219 it is a mid-range professional corded multi-tool, and ToolGuyd called it a better value than the Fein MultiMaster in 2017 while judging Fein slightly better outright. If StarlockMax compatibility is what you need, buy the GOP55-36 instead. [4][5][1]
Named alternatives:
- Bosch GOP55-36 — the StarlockMax model; buy it when you need StarlockMax accessories, which the GOP40-30C mount will not accept. [1]
- Fein MultiMaster — the tool ToolGuyd considered slightly better in absolute terms but more expensive; choose it when you want Fein’s quality and can pay more. [5]
