Dewalt DW660 vs Makita RT0701C

Any advise on how the Dewalt DW660 and Makita RT0701C compare for cutting aluminum.

Does the Makita have any advantages for aluminum? If not I’ll go with the DW660 as it’s cheaper.


I don’t think you would notice any difference.

It might be a bit larger so it would sit further from the corner meaning slightly less rigid.

But if it doesn’t it might be heavier so slower accelerations.

Having a speed control is nice, but if we ever get a inexpensive PID up and running, moot point.

Bottom line, Sorry I havn’t tried it. If the dewalt is cheaper, I see no reason to switch, it plows right through aluminum. Shouldn’t be a torque deficiency, we have pretty much maxed out our rails more than anything else. I have never looked for a strong spindle for any reason.

If you want to go faster build it smaller.

Man, taking a second look at that, it might just be smaller. Hmm. I wonder. Seems pretty nice actually. Easier to mount that’s for sure. All comes down to the bulge on top and how it sits.

If I remember to bring in the calipers to the hardware store I will take a look.

It only comes with a 1/4" collet that is a bummer.

I have the Makita RT0701C and I like it but I think the Dewalt DW660 might be a better choice. With the tool mount I have, the Makita hangs out 75mm (3") from the Z axis stepper. With a redesigned mount it may be possible to get it 10mm closer but I think the Dewalt mount might be closer than that, Ryan? I believe the Dewalt is slightly lighter as well.

I use this for the 1/8" collet and it works fine despite the warnings not to use it in a router. It stays in place nicely.

The big benefit of the Makita is the speed control (10,000 - 30,000 rpm) but I have not cut aluminum yet so I’m not sure how important that is. Maybe the aluminum cutters can chime in?

I have a clone of the Makita, the Katsu. It’s thought by some to be a re-badge because it’s pretty identical.

Anyway they both seem to share one thing vs the Dewalt, which is downward air flow onto the work piece. First noticed by me when trying to follow the cuts around with a vac, only to find dust was all over the workshop. Oh well, it forced me to get on with the dust shoe, so it’s not a problem.

Just this minute discovered there is an air diverter out there, but haven’t found the model files for it as yet.

As Ryan says, the Makita doesn’t have the 1/8" collet option, which may hamper you when choosing bits. The best option (Elaire recommended by Ryan) for this is found here:

They don’t make a 240v Dewalt, so I chose the Katsu, but have recently obtained a 240-110v site transformer, so thinking again.

Regarding the Makita’s speed control, I understand the Dewalt is proven for alu cuts, but I can’t help think when drilling, RPMs are lower for metal. Does this have any bearing? Another question would be does the Makita carry the same torque at lower RPMs? I would guess no.

Here’s the dust shoe I use with the Makita:

It diverts the downward airflow.

Most of us have a speed controller on our 660’s, is it as strong at lower RPM, probably not. It does 100% still have more than enough power. That is sort of the reason for buying the 660. We didn’t start with it it was a process of trial and error for the first year. That first year people were strapping on giant routers, nema 23’s, double gantries, assuming we needed more power…they milled slower. 600W “spindle” seems to be a great range, even at less power it tends to have more than enough.

When the CAM is set right you really can rip though all sorts of material. This is 100% the most important step, slap on a dremel and you will be fine if your cam is set accordingly. I have been cutting some 3/8" HDPE recently and I now cut full depth, I used to cut 1/4" in two steps, HAHAHA fool. I had a single flute cutter on there at 6mm/s slotting with a 0.5mm finishing pass. That had my router on the slowest speed, meaning I need to move faster, but I cut the part I needed in 5 minutes and the dimensions were dead nuts. Sometimes you need to push the machine harder in this case I do. Turns out slow shallow cuts are just as bad as fast deep cuts sometimes. once you get in the correct range it really just slides through.

I bring it up a lot but you have to see Kevin rip through aluminum…ridiculous and the machine isn’t even that small.
