We've had a few customers in sheet metal fabrication ask for something that could handle tight spots around pre-drilled holes, and this is what we send them — it's basically a lightweight air tool that fits right in your hand.

It runs at 2800rpm with no load on 0.6-0.8MPa air pressrue, and air consumption is about 0.3m³/min so it won't tax your compressor too much; the minimum plate thickness is 2mm, and the hole diameter it can work on is 7mm (usually a common size for small pass-throughs).

You'll find it's better than a standard angle grinder for chamfering edges on thin metal, but it's not suited for heavy stock removal or any work on thicker steel plates over maybe 3mm — just a real limitation to know up front, and teh blue paint does chip eventually but that's cosmetic.

Also, lead time is roughly 20 days or so, and our company provide inspection reports with each unit.

that buyers don't always ask about: the hose fitting is a standerd 1/4-inch NPT, so check your quick-connect coupler.

MOQ is usually 10 units give or take, and the defects.
It works on plates as thin as 2mm, so you're good for most standard metal sheets.
No, the minimum hole diameter is 7mm—anything smaller won't fit the cutter properly.
Yes, we include inspection reports for every tool, so you can verify the quality before use.
Standard lead time is around 2-3 weeks for that quantity, but we can confirm once you place the order.
Yes, it's designed for metal workpieces, including stainless steel, as long as the thickness is 2mm or more.
