SainSmart Genmitsu 10Pcs Nano Blue Coat Flat Nose End Mill CNC Router Bits, 1/8" Shank Spiral Upcut 2 Flute End Mill Set (3.175 x 17 x 38mm)

I just used this bit on my small CNC machine and am very pleased with the results. Since I will be using it on wood, I can’t comment on how durable it would be on metal. For my application, it is perfect and at a great price.

Arrived on time great buy

My goal with these was to avoid having to cut out EVA for Halloween costumes by hand. I'm still dialing it in but saw ok results by running them at 20K rpm and 65ipm through some 6mm EVA (and .75mm of MDF sac-board). They leave a cleanish left edge and a ragged right edge. Looks like there was still some wobble on the edge, so I'll probably slow it down a bit the next time I use them.

Great Product, fits and works perfect at a competitive price.

v. good

So I’m kinda new to CNC but these haven’t broken and have stayed sharp beyond my expectations. What else could there be to ask for?

I have used about four packages of these for my CNC. They last a good while, but the best thing is never feeling bad about changing to a new one with the low price.If you are cutting detailed 3D projects, this is not the right end mill. If you are cutting repetitive, low precision products, these are great. I have cut 100s and 100s of xmas ornaments over the last month, all using these bits.

Right out of the box they're not as sharp as better quality brands. Definitely a lower grade carbide as well, but for half or less than half the cost of a quality cutting bit they're ok I guess.
