As a machinist I used it all day today and works great. I can use small taps from 10-32 and up. Sturdy and durable sturdy body. It will take a long time.
Last I checked, 3/4 inch is about 19mm. This device only erases 16.2mm or closer to 5/8 inch. I want the description to be correct as I cannot use it for the application I ordered it for.
Needed a tap handle that could take the 7/16" square end on the tap I had. how to work with the pins (since one of them is screwed in to clamp the faucet attachment). For casual tapping, which is all I'll ever use it for, it works well. It seems quite heavy, although I just tapped on the plastic the first time I tried it. Use this tool. I think it's good for the money.
