I have built and been using the MPCNC with the DW660 cut out tool. I want to start experimenting with tool changing and using bits like chamfering bits, ball nose bits, etc. but would prefer to use cheap endmills while I learn. Problem is that all I can find on sites like aliexpress and banggood are metric endmills. Does anyone have any links for 1/8in ball nose, chamfering, v-bit, flat, etc. endmills on these sites and/or can I use 3mm endmills in the DW660 collet?
