  • Great little corn cobs
Size: 0.8-3mm
The 1/8 cob cut bits are monsters, Love 'em, wish I could buy them in a stand alone pack. I just sit like a cave man and watch them granulate steel. I've always thought that chips were the way to go but these little guys showed my something different. I thought that these were more for wood and such and only grabbed it off my shelf out of desperation but they cut well. I had to feed it a slow cutting speed (.001 or so per sec at 900 rpm) but it worked like a charm on 1045. I chewed one up after about an hour, but I had gotten a little impatient and dinged the very tip up. The flutes kept cutting! The price on these is good, like I said, just wish I could buy the 3mm in multi packs by themselves. ... show more

  • Great bits

These bits work great and cut clean

  • Update, to 4 stars
Size: 0.8-3mm
The smaller bits are not very durable. Seem to be brittle and prone to breakage. I thought at first it was just me pushing it to fast but reducing the the speed did not help. Update, Customer support supplied me with replacement bits and these are working much better.

  • Very tough and sharp.
Size: 1.5-3.175mm
I have used these to cut wood, plastic, aluminum, hardened steel, and stainless steel. So far they have worked very well and are still sharp as new. Haven’t burned up any of them yet. I like ‘em!!

  • Second Set
Size: 1.5-3.175mm
I first got a set with my CNC machine and have been using them for 3 months. I'm cutting something with them almost everyday, mostly plywood, and they have been durable. the bits are still in great shape and cutting clean. I know that they will eventually going to wear out with how much I use them but they show no signs of slowing down for now. I was so impressed that I ordered a second set since I saw them as a great price on Amazon. The set includes most of what you will need for a CNC machine with a 1/8 collet. It does not include the "V" cutters. ... show more

  • Smaller bits are not durable
Size: 0.8-3mm
small bits lasted 1 pass then broke. I was even cutting MDF. I adjusted my feed rates and pass depths accordingly for the small bits. The larger bits do cut, but i feel they do not cut as cleanly as a standard spiral up or down bit. Price is cheap, so i gave them a shot, but i wont purchase these bits again and i have put them aside for now. ... show more

  • Update
Size: 0.8-3mm
I previously reviewed this item at one star due to not receiving a complete set. Sainsmart reached out to me immediately and replaced the set. They explained that the set came from a fulfillment center but were not trying to shift responsibility elsewhere. I used it this past weekend and was very satisfied with the results. I noticed some reviews saying the bits broke easily but I have not found this to be the case. I spoke to other friends who have this product and they mentioned adjusting the speed at which the router cuts in order not to stress some of the thinner bits. Overall I am pleased with the purchase and VERY pleased with the company and their response. ... show more
