Nice little bits

I run them on the slowest speed of my Dewalt (with adapter collet) and they happily chew away at the wood, leaving a smooth surface in their wake. The smallest bit (my fav) arrived with a broken tip. Not a deal breaker and now I can also attest to their excellent customer service as it was immediately replaced. I'll definitely order more after I wear these out.

Nice bits for cnc

Works great for my cnc machine and most of the bits will last you a long time. Only bit I had break on me was the 0.8mm and that was at slow speed. But I havent had any problems with the others. Knock on wood lol

Price was reasonable

Just starting out with CNC routing and needed bits on hand. This seemed like a deal but, now I can't find a reference to using this type of bit. Was probably a hasty purchase since I didn't know what I would need. There may be a use for these so I'll keep them. They look good.

Affordable and effective

So far these have worked great for cutting wood. Just be sure to get your feeds and speeds right. Run them too fast and you break them, run them too slow and you create friction which heats them up until the either break our wear out very fast. Even the most expensive endmills in the world can be destroyed by operator error. I got good results cutting hardwood with the 1.4mm bit using SFM: 141, chipload of .005, and a depth of cut of .0157 (4mm). I would not probably not recommend cutting metal with these, but I have not tried it yet.

Includes a 1/8" Bit! Cheap, Works

I bought these for a desktop CNC machine powered by a dremel. The shank fits a little snug, but not too snug. I've been using them to cut maple and they seem to be working just fine. Unlike many of the similar kits, this actually includes a 1/8" bit which is nice if you're an idiot like me and you designed a complicated project around that instead of 3mm.

I've probably done about 20 hours of cutting without issue on the 3.175mm bit and 10 hours on the 1/8" bit with no trouble so far.
