Kodiak Cutting Tools KCT137388 USA Made Premium Solid Carbide End Mill, Extra Long, 2 Flute, 1/4", 1-1/2" Length of Cut, 4" Overall Length

These are poorly made and break incredibly easily while doing the most basic of cuts. I've bought these twice and each one broke in the same exact spot. They are horrible and crap quality

This is a nice bit. I bought it to cut out the project in the picture. It was 2 1/2 inch thick solid walnut. The added length caused a little chatter in the cutout and I had to slow down the speed considerably and limit the depth of cut on each pass to get the job done. I was actually worried the bit was going to shatter when it would chatter while running too fast. No regrets but this project was about all this but wanted to tackle. I would but again

I bought this to cut a 2 3/8 guitar body. The bit cuts well, but chatters a bit due to the length, which causes chipping. Cut very slow with this bit. Overall it got the job done.

Super smooth grinds. Using in high speed spindle at 28k- you'd know if they weren't balanced. Have since order about 10 other bits from them- and they're all exceptional!

I saw nothing wrong with this but I ended up not being able to use it.

I use this bit for my CNC routing out deep pockets. It is kind of a specialty bit, so I have only used it a few times, although I suppose you could use this for a primary go-to bit if you wanted to. I have other shorter bits that I primarily use though. I really like having this bit around.

Smooth steady cuts. Jumps twice and bit breaks inside router. Im stuck with a broken bit, unfinished project, and broken router. But before incident, the bit worked perfectly. Cutting metal like butter. S#!% happens.

High quality and stays sharp. I've used this several times and it has not disappointed in any way.
