These are high quality nozzles. They are just not quite what I thought based on the product photo and description. for use with a Dremel tool. They are fairly short for use with a standard drill. They may work - and that's how I use them - but they're actually much better suited for use in a small, high-speed rotary tool like a Dremel. I still give them 5 stars - they work great and are durable. to me.
