Sharp, Reliable, and Perfect for Fine Detail Work
Size: 1/8"CED x 1/8"SD x 11/16"CEL x 1-1/2"OAL
This HQMaster bit set is a go-to for small-scale CNC carving and engraving. The 1/8" shank fits snugly in compact routers, and the flat nose two-flute design gives clean, accurate cuts in wood, plastic, and soft metals. I’ve used them for pocketing, profiling, and fine lettering, and they consistently deliver smooth edges with minimal cleanup. Carbide quality is solid—no premature dulling, even after extended runs in hardwoods. The flutes clear chips efficiently, and the bits run true with no chatter. Great for hobbyists, sign makers, and anyone doing precision work on a desktop CNC. If you need dependable small-diameter bits that hold up under real-world use, this set delivers. Excellent value and performance

Great Bits at a Great Price
Size: 1/8"CED x 1/8"SD x 11/16"CEL x 1-1/2"OAL
These bits work great. They were reasonably priced. I love the convenience of having 10 bits in a set, since small diameter bits can break frequently when used hard by my students. They were well packed, arrived quickly, and are of high quality. I am a satisfied customer.

cuts well in birch ply, MDF, poplar and hardyboard
Size: 1/8"CED x 1/8"SD x 11/16"CEL x 1-1/2"OAL
Wanted to experiment with some different 1/8" shank upcut spiral bits. So far these have done pretty well in birch ply, poplar, hardyboard and MDF. The man-made materials will cause much more wear on the bits. But even after cutting up several template pieces from 1/2" MDF, I was still getting clean cuts in poplar which can tend to be a bit stringy and fuzzy with a dull bit. Bit diameter was right on the money for a 1/8" (3.175mm) cut.

These bits work well

I'm using them in my CNC and they seem to be sharp and work well. I've made a few projects with them and they are still sharp.

Waaaay better bits for a CNC machine than the standard RotoZip bits I've been using.
Size: 1/8"CED x 1/8"SD x 11/16"CEL x 1-1/2"OAL
So I built a very cheap and loose CNC machine using a RotoZip as a router. I was originally very disappointed with its performance. After swapping the spiral cutting bit made for the RotoZip with one of these HQMaster router bits, I feel much, much better. The old RZ cutting bit could not run properly even at 100 mm/min with a layer depth of just half a millimeter. My CNC uses small NEMA 17 86 oz/in motors with 5/16 18 tpi threaded rod for the axes (yes, cheap build). It was hard for the motors to push the bit even at this slow speed and very low cutting depth and it skipped lots of steps. When I tried this HQMaster bit I got it to go at 300 mm/min with a layer depth of 2 mm and it was like going through butter (in 19 mm pine board), without the X/Y motors skipping. It can probably do even better (faster and larger layer depth) but that's as far as I've pushed it this evening. Still, it's way, way ahead of the normal RotoZip cutting bit. Additionally, when it cuts, it barely makes any more sound than the router normally makes spinning freely, the old RZ bit was very loud when it was (barely) cutting. I even had an accidental command move this HQ bit cutting at a depth of about 10 mm through the pine, and though the motors were skipping at 300 mm/min, it still went through the wood a few centimeters before I could eStop the machine. Getting 10 bits at this price is amazing because the normal (and much less capable) RotoZip bits are around $8 at Home Depot. The only advantage with the standard RZ bits is that they are much longer, I can get about 20 mm of total cutting depth with these HQ bits, which is enough for my purposes. Now, my cheapo CNC can actually be used to make better parts for itself. I'm very glad I made this purchase, these bits make all the difference in the world for my CNC.

Size: 1/8"CED x 1/8"SD x 11/16"CEL x 1-1/2"OAL
Edit #2: It has been almost a year since I purchased 60 bits - I was able to make the bits last but I went through a lot of bits before I had it figured out. I have now changed the review to 3 stars from 1 star. I use these bits to cut cast acrylic. Instead of doing multiple passes, I ended up going with a very slow single pass. I would then do a fast final clean up pass. My settings for 0.4" thick acrylic: Ramp in, 6 IPM plunge (Z-axis), 12 IPM cutting speed, 18,500 RPM. Final pass: 15 IPM plunge, 30 IPM cutting speed, 15,000 RPM. Doing it as 1 pass + 1 fast clean up pass actually cut down my machining time by quite a lot. I'm thankful for that but it makes me wonder what I could have done with the original bits in terms of machining time. I'm going to buy a couple more and see how they fare. I think that the single pass helps with the deflection since it isn't cutting only at the tip. The deflection was probably what was causing the bits to break so fast. With the above settings I use the bit for about 2 hours, then switch to a new bit with a new job. Doing it this way I didn't have any bits that broke in the middle of a job. I might use old bits if I don't care too much about surface finish and just need something cut to rough size. We'll see if the bits I'm about to order work with my new expectations. - old review below - Edit: Changed to 1 star out of frustration with trying to use these bits - gone through 20+ bits so far, for the old version bits I would be on my 2nd or 3rd bit. Original review below. I've been using these bits to cut through ~0.4" thick cast acrylic using a CNC router. They worked well until I needed to get more bits - they changed/simplified the cutter geometry recently. The change in geometry seems to have made the actual thickness of the bit material thinner if that makes sense. There isn't a visible "edge", instead it looks more like "cones". I did have some of the previous bits break but typically the bit would break because they had gotten dull. I would usually have a bit be able to last through 5+ hours of constant cutting. Used the same settings as I had done before and I broke a bit in less than a minute. I started tweaking the settings to see if I could actually use the new bits and I broke 5 bits in the process. Ended up having to do lighter passes (from 0.125" to 0.09") and slightly higher RPM got a bit to last almost an hour but it still ended up breaking. I used to do 3 passes at 0.125", had to go to 4 passes at 0.09" for these new bits and am currently trying 5 passes and seeing how far I can get with that. Current settings are 0.075" cut depth, 25 IPM, 18000 RPM. If you look closely at the attached picture, the bit on left has a visible "edge" and looks more parallel. The bit on the left is an old/used bit. The one on the right is new bit with the cutting edge at the bottom of the "cone" and the bit has visible tapers when look at it from the side. It would have been nice to know that the cutter geometry changed before I ordered 60 bits. Previous bits were a great deal for me. Now it seems like I need about 5 bits to finish 1 job - just not worth the time. Seems like a bait and switch. The old bits were much better value.

Little bits, big results.
Size: 1/8"CED x 1/8"SD x 11/16"CEL x 1-1/2"OAL
I really like using .125" diameter bits with my CNC. When one gets destroyed there is no problem due to the price. These stay sharp for many of my projects. In 20 years I have only managed to break one. I guess I haven't been trying hard enough... These have worked well for different woods and wood products, and plastics.
