HQMaster CNC Router Bit 1 8 Shank Ball Nose End Mill Cutting Dia. Spiral Milling Cutter Engraving Carving Tool Set Tungsten Steel for MDF Acrylic Wood PVC 10Pcs

For the money these hold up pretty good. I have been using them since last spring on hardwood of various types and they seem to do fine. I change them out after a few carvings. On my second box.I ordered some expensive UK bits this past summer and blew though all three of them in three weeks - very fragile.

Perfect, Exactly what I needed. Thank you

They are made with great quality, for the price. You can't beat it! If you go easy on your bits they will last!

Update after one year: After originally purchasing these, I had found I had an issue with the bits. HQMaster immediately replaced them, and I’ve now run them almost a year and have only had one break, and that was due to a programming fault that rammed the bit into the deck of the CnC machine. Really impressive considered I use the primarily for cutting billet aluminum Update after 2 weeks of purchase HQMaster sent me a new batch of bits, and there is improvement. I added pictures, and one shows 2 of the new batch at different rotations compared to 2 of the original batch. There seems to be a difference in thickness where the flute ends into the shaft. I don't have a micrometer to confirm this, but with the new batch I was able to load up a bit and run a cut of a 30mm circle into 3/8" aluminum. With the original set I could get one of the bits to break after going maybe only 2-4mm deep into the material. The new bit had no issues. Inspecting it afterwards compared to another of the new batch, you can see a little smoothing at the end of the 'ball'-ish area, but nothing snapped or broke.2nd update: I've now run more than two weeks with this new set of bits and have yet to have one break. HQMaster did me right on this one. Review updated to 5 starsOriginal Review: The flute on these bits comes up and leaves a large flat area on the shaft, that is narrower than the cutting portion of the bit even. This leaves this area weak and makes the bit very prone to breaking. I broke 4 in my first week. After the first I thought I must have the feed rate wrong on my carve, so I slowed it down - and then proceeded to have 3 more break with no more than an hour’s carve time on any of them. I kept those pieces and saw they all broke in the exact same spot. This manufacturer needs to redesign the geometry of the end of the flute, or this product should just be avoided.

These are great value . I have tried these on some relief carves on wood and it does what I expect to do . Pretty smooth finishes . I have not tried other expensive bits .. but she am happy with the finish so will stick to these for now

I usually have good luck with this company, but this last set I have broken 3 of the bits carving Poplar; Maybe I was just got a bad set, but it's sad when you are working on a project and it has to be started over because of a bad bit.

You get what pay for. They are not as accurate as I would like to make a good-looking cut. For roughing they were OK, but not great. They are a total steel bit and not carbide. Again, you get what you pay for. I expected them to be a little better bit than they are. If you are just starting out then they are a good bit to start with.

works great
