I am finally getting back to my MPCNC after a hiatus. I am printing the new part now and will be picking up a 660 as well. My question is what is a good endmill to start with? I plan to do wood and aluminum so I am looking for something that is multipurpose if that exists.
I see a few options in the store and I know that there are a ton on amazon but I am just not sure what would be best for my purpose.November 11, 2016 at 7:48 am #20849
Probably a 2 flute 1/8 for the wood… maybe a downccut for the first pass if you’re worried about the finish. What all do you want to do? I wound up with some ball nose and v-bits after a little while. If carving or engraving is in your future, might as well get a couple of those too. Oh, maybe something bigger for surfacing your board if that’s an issue.
I can’t say much about the aluminum, as I haven’t tried to cut any. Probably a single flute, especially if you can’t control the RPM on your spindle.November 11, 2016 at 5:19 pm #20860
ok great. Do you know if there are any bits that are ok for both wood and aluminum?November 11, 2016 at 9:07 pm #20872
Sorry, no. Most of the endmills I have are rated for aluminum and wood, but I’ve never cut any aluminum on mine. Maybe somebody with more experience could weigh in.November 11, 2016 at 9:13 pm #20875
Any bit that works on aluminum will work on wood, but there are wood specific bits that do a better job. There are so many different kinds of end mills it is very confusing. I end up getting what I think is rigthh and just sticking with it. That is why I don’t have a huge selection in the shop, all the bits in there cover most of the bases without getting crazy.
There are some super tuned wood mills out there for $100+ they have a tight spiral on the very end and a big wide spiral for the rest to cut well and kick out the chips faster. But that is a whole different rabbit hole.
If you are new to it, just get a single or double flute end mill and it can work for all materials. Specialized bits offer faster cutting and better surface finish usually.November 12, 2016 at 8:14 am #20890
Yea, The number of options are a little overwhelming. I am thinking about starting with this one: https://vicious1-com.myshopify.com/collections/sharp-stuff/products/1-8-2-flute-endmill
What do you think?November 12, 2016 at 8:35 am #20893
Exactly, that is the standard endmill. But start by learning on foam, then wood, then plastic, then metal. You will see how feeds/speeds and depth of cut matter more and more as you make that progression. Trust me way better to take the time to learn the progression.
