Review on ASNOMY 1Pc Carbide Square Mill Cutting Tools by Shigg Bigbee

I ordered this bit thinking it was actually a 3/8 end mill. The ad text says "3/8 (10mm)" which led me to believe it was an SAE size cutter and "(10mm)" was just a reference size for people who don't normally use one bypass US sizes. Unfortunately, this cutter is actually a 10mm diameter end mill (about .020 over 3/8) and doesn't fit my SAE size holders. I'd love to use it as it looks well made (hence the 2 stars) but until I get metric holders this tool will just gather dust. Pay attention. you have been warned
