So I completely understand the get what you pay for concept. And anybody shopping for small carbide end mills has seen the 10 for $5 sets on eBay from Hong Kong Etc... Vs the 1 for $20 bits for sale domestically. I'm specifically referring to the small sizes for fine detail and sharp corner clean up such as .8 mm or .03" (or smaller) size with the little plastic depth stop. As I get more into CNC inlay cutting I know I'm going to be snapping quite a few of these little suckers until I nail down optimal speed and feed rates. (Peviously done by hand or via laser) I understand that there are different grades of carbide... but for these tiny bits... Are the expensive bits really that much better? Or are they just highly marked up versions of similar products made overseas anyway?
