Worked well for guitar fret slots

Used to cut fret slots on a hard maple guitar fretboard. Worked great! Didn't break the bit, surprisingly. 18000 rpm, 80 ipm (40ipm also worked), 1.5mm depth overall (0.1mm per pass). I might try 0.2mm per pass next time, but I can only recommend starting with 0.1mm per pass.

Hold up well for working with wood

I make awards and recognition plaques for our heroes, military, first responders, health care, and home and office. These end mill bits are tremendous and last a long time. I cut .075 deep with no problem and sometimes even .10 deep. I may need up to 6 passes to create a letter, but the first one is the critical one as it is fully embedded in the material, normally I make two passes, but for a .1" cut I will make 3.

Great end mills for the price.

I use them all the time for projects in 6061 aluminum with no issues. If you read the other reviews i can tell you they have no clue on what they are doing. If you know feeds & speeds for your material these will last a good amount of time. If you plan on using these small end mills use flood coolant of mist with allot of chip clearing.
