HOZLY 1/8 Shank Titanium Nitride Coated Carbide PCB CNC Drill Bits Router 0.8mm Cuting Dia for Print Circuit Board Pack of 10

Was worried that these would break, but I was able to use the full cutting length on hardwood (walnut) in my CNC router without issue. Just go slow, and make sure to use compressed air to clear chips while cutting and they will work well for you.

Good mills for the money, have tried other brands and learned my lesson, will be sticking to Holzy.

I ran these at half the speed I run the stock bits and they still broke very quickly. I am returning them and looking for something else.

Poorly made bits. Even on the slowest lightest passes they would snag and break on pine boards. They may be affordable but you get what you pay for.

bits break to easy

I use these to finish the drill holes on drilled pearls. Broke a couple but it was my fault as I was too impatient. Very fine, so thin of course. Slow and steady does the trick.
