How We Test & Compile Our Compatibility Guides

ToolCompatibility exists to answer one question: will this fit / work with that? This page explains how our guides are compiled, what we do and do not do, and how we handle affiliate links, so you can judge how much weight to give our information.

Important: we do not physically test products. Unless a specific page clearly says otherwise, our compatibility information is compiled from manufacturer specifications, manuals and published standards — not from hands-on testing in a workshop. ToolCompatibility is independent and is not affiliated with, endorsed by, or approved by any tool manufacturer.

1. We start from primary sources

Manufacturer specification sheets, official manuals, and published engineering standards come first. Retailer product listings are treated as leads to verify, not facts — they’re frequently wrong or copy-pasted.

2. We check the physical standards, not just the marketing

Compatibility usually comes down to measurable things: disc bore and diameter, arbor size, battery voltage and footprint, connector and shank type, thread pitch. We work from those numbers, because they don’t change with a rebrand.

3. We separate “fits” from “is safe and sensible”

A part fitting isn’t the same as it being the right choice. Where a combination is physically possible but risky, under-rated, or voids a warranty, we say so.

4. We flag uncertainty instead of guessing

If we can’t confirm a detail against a reliable source, the guide states that plainly rather than presenting a guess as fact.

5. We try to keep it current

Tool ranges get superseded and specifications change. We update guides when we become aware of changes, but we cannot guarantee that every page reflects the latest manufacturer information. If you spot an error, please contact us and we will check it.

6. Our recommendations and affiliate links

Some links on this site are affiliate links — if you buy through them we may earn a small commission, at no extra cost to you. As an Amazon Associate, we earn from qualifying purchases. Commission does not determine which products we mention, but you should be aware that we have a commercial interest in the links on this site. Where we describe a product as a pick or recommendation, it is based on published specifications and fitment, not on our own testing.

⚠️ A note on safety. Power tools and accessories carry real risk — especially anything spinning at speed, like cutting and grinding discs. Always match the accessory’s maximum-rated speed and size to your tool, follow the manufacturer’s guarding and PPE guidance, and never exceed rated limits. Our guides help you choose the right accessory; they don’t replace your tool’s safety instructions.

This page is for general information only. We work to keep details accurate, but specifications change — always confirm against the manufacturer’s current specification before buying or using a part. Found an error? Contact us.
