I am building my MPCNC and plan on using a DW660. Any recommendations for affordable/useful bits to start with? I’m not even sure what kind of bits I need. My first projects will be engraved signs, similar to this person’s project: https://youtu.be/oBRhfsY5Oc8. I was looking at these: http://www.amazon.com/End-Mill-Set-Piece-Flute/dp/B002YPHSIG/ref=sr_1_3?ie=UTF8&qid=1444140834&sr=8-3&keywords=end+mill.
In keeping with the spirit of the MPCNC and my budget, I’d like to not have to spend a fortune on them.
Thanks for any advice!October 6, 2015 at 2:02 pm #3385
I am looking into mills (bits) as well. Just got the DW660 too. It will accept either 1/4″ or 1/8″ shank mills. The link you posted is for mills with 3/8, 1/2, 5/8, 3/4 inch shanks. It came with a simple roto-zip style mill that should cut foam board or wood at least. I plan on using thick foam board to practice on. Still a lot of terminology to learn.

Good catch – shows how little I know and how much I need to learn! Maybe I’ll wait and use the whatever comes with it at first. I also have a set of router bits – maybe one of those will be useful. Thanks!October 8, 2015 at 6:23 am #3394
Try something like these, http://amzn.to/1JURIfZ
Start with an 1/8″ 2 flute bit made for wood. when you have a few cuts under your belt you could probably move up to a 1/4″ and work faster. like this http://amzn.to/1LjTpZP, on a 1/4″ you might be able to get away with 4 flutes.
Drillman 1 on ebay has an amazing selection with prices to match, good guy. My advice is stick with 18″ at first, only move to 1/4″ when things are running smoothly.October 10, 2015 at 6:52 pm #3454
I bought a set of 1/8″ shank 1/8″ endmill bits from drillman1 and really like them. I also bought his micro kit with the 1/32″-1/8″ endmills. Do you have any recomendations for the tool settings within Estlcam? Depth per step? cut feedrate? plunge feedrate? At least something to start with?October 10, 2015 at 11:46 pm #3460
It all depends on the material being cut and what spindle you are using. My videos have the settings I used in the descriptions. I always use a 45% step over for roughing and 2-10% finishing. Plunge slow to start, the z axis is geared a bit high, plunge to fast and you will skip steps.October 11, 2015 at 5:03 pm #3488
So….assuming soft wood like pine, can you give me a decent starting point or a threshold to stay below?October 12, 2015 at 7:36 am #3495
In this video I used .5mm DOC, 20mm/s, finishing was .25 DOC, 35mm/s 45% step over. You should use these as a first test cut but after your sure everything is working smoothly use a 2mm DOC and work up from there. Keep the finishing DOC and speed the same and use a low step over.October 12, 2015 at 4:25 pm #3500
So I ordered these to start with: http://www.amazon.com/gp/product/B010NI39WO?psc=1&redirect=true&ref_=oh_aui_detailpage_o05_s00.
I was wondering about dressing the waste board. Most fly cutter bits seem very expensive, and it will probably take quite a while to do it with a 1/8 bit (my bed is 20×30 inches). Do these look like they might be good for dressing?
Thanks for your opinions!October 15, 2015 at 6:24 am #3529
My waste board has not been far enough off for me to worry about it. That or I haven’t needed that kind of accuracy.
I would just run 1 pass over the whole bed with the 1/8″ shouldn’t take more than 20 minutes. Just take off the minimum to flatten it out, and run it a bit faster than normal.December 2, 2015 at 1:14 pm #4534
How about bits for doing carving? I saw some videos of sign making in wood with a pointy bit but I don’t know what it’s called. Not the engraving bits – I can find those on Amazon just fine.December 2, 2015 at 1:41 pm #4537
Try a V-Bit, there are a few different angle that give a different effect.December 2, 2015 at 2:09 pm #4545
I would reccomend any 1/4″ shank carbide router bits. V groove 45deg and 60 degree, and round nose, and a set of staight bits.December 3, 2015 at 10:31 am #4570
