This Speed and Feed Chart had the settings for the Dewalt 611 router but not the Makita 0701,
I added a column for the Makita 0701 and also the standard settings for both routers at the bottom.
I did a few of the conversions in the Makita column. Ill repost when i get time to do the rest
Dial # 1 2 3 4 5 6
RPM 16k 18.2K 20.4K 22.6K 24.8k 27K
Dial # 1 2 3 4 5 6
RPM 10k 12K 17K 22K 27k 30K

Sorry for some reason the file didnt attach
If someone has a tachometer it would be easier to recalculate the spindle speeds for the Makits

What diameter tool is used?.
Ok, so here’s the conversion chart from Dewalt to Makita. You can plug these numbers into the speed chart in column E as needed. These are calculated not actual RPM readings but they should be pretty close. I included all Dewalt and Makita speed settings from 1 to 6 on the dial in 10% increments.
I tired some of these settings for 1/8 and 1/4 flat cutters on both PVC and MDF and they worked fine along with the DOC, Feed Rate, and Plunge and they worked fine.

I’m curious what formula you used in Excel to get the values. I wanted to be able to get exact speeds based on each .25 dial turn (since thats the increments marked on the Makita dial) so I did some interpolation and came up with my own formula a while back in a spreadsheet. I never published it because I wasn’t sure how correct they are. My values closely match yours throughout your table but diverge slightly above dial setting 4 or so.
For any given input value X (where that is the desired RPM you want to achieve) I used the following Excel formula to get a dial setting:
All the CEILING command does is take a value and round it to the nearest 0.25 value. If I remember right I used a basic linear fit formula based on the known values for each whole number dial setting to get the formula overall. Since its a simple mx+b linear formula it may not be a best fit model.
I didnt use a formula. I pretty much did it manually. Here’s how i did it.
- I wrote down the published speed settings for both the Dewalt and the Makita for 1 thru 6
Example: Makita 1 = 10k 2 = 12k etc
Then I subtracted 1 from 2 which gives me 2k
Then I divided 2k by 10 which gives me 200
Then add 200 to value 1 (10k) which gives me the speed of 10.2 for setting 1.1
Do that again till i get to 2.0 and start over again
Since the speeds are not quite linear between the different dial settings i recalculated between each of the speed dial settings.
e mail me and i will send you the spreadsheet if you want
