So I've search High and Low, tried a WIDE range of settings and still cant dial it in.. I'm going broke from buying bits so i need some advice.
Literally everything i've tried doesnt work. gwizard settings, calling manufacture (amana) trial and error, youtube videos, etc.
Machine: cncrouterparts 24x48
Spinde: Bosch 1617
Mods: precision bit collet
Material thickness: .040-.050
Bit: all the bit's i've use are 1/8 diameter and 1 flute (o flute (amana and ebay brand), kyocera single endmill)
Coolant- I've used wd40 but im trying to avoid coolant since im still on a mdf bed- and from my understanding .040 is thin enough where coolant isnt needed (judging from what i've seen on youtube and other threads)
Hold down- double sided tape (forgot which kind but found it on the site- not the sticky gooey carpet tape)
From what I've gathered, it isnt uncommon for DOC: .125 so I've been using .040 figuring that is "safe"
IPM i've tried 20-90
RPMs 8000-2400
I've used these/amana with some success @ 30IPM, ~ 14000 rpm .040-.050 DOC I did manage to get a bunch of cuts at this setting with no coolant and nice chips

The Kyocera bits i just got. I have yet to successfully cut anything from them. i've tried 30ipm at 13500rpm, 60ipm @ 24000rpm etc. i have not had "chips" with these bits, it just gums like crazy. I was under the assumption a lot of people use this bit for aluminum since i read it was recommend to buy from "drillman1" on ebay.. any suggestions?

And these I have on order- Figured I tried 2 flute since i've only experimented with 1..

Any suggestions would be great. Like I said I used the trial of g-wizard and all those setting resulted in broken bits... I have to be missing something.... I've already broken 35+ bits and cant justify buying anymore amana bits at $30+ a pop only to break.. (broken about 8 already including 2 $50 1/4 bits that broke IMMEDIATELY after using the settings the tech told me..... which is why i rather not use amana bits)
