HQMaster Spiral Router Bits Down Cut 1/4 inch Shank Solid Carbide Nano Blue Coated Spiral Downcut CNC Bits End Mill for Wood Cut Carving Engraver (1/8 Cutting Diameter)

This 1/8 cutting 1/4 shank ball nose bit came in a standard end mill case that protected it during transit. The case was nicely labeled so you dont have to. The nano-blue coating covered the top end of the bit evenly and cleanly. The ball nose left a nicely rounded bottom on the groove. The bit cut easily and dispelled chips well due to the up-cut flute design. This bit seems well designed and stayed sharp through my testing on both soft and hardwoods and I expect to get a good long life out of this bit.

Great bit nice and sharp measured to meet specifications. I like the way these bits cut nice and clean.

This is a great end mill for doing 3d cutting. Makes nice clean cuts leaving a nice finish. The price makes this even a better value. Time will tell but so far this has been my goto bit for 3d cuts. Comes packaged well and arrived quickly. I will buy more of these bits

Like clamps, you can never heave enough router bits. Well, that is my take. And like they last forever, right? This bit is well made, good fit and finish. So far it cuts as it should, cuts very nicely. I cant say how it will last, that will take time and use, but Ill update this if anything changes. Comes in a nice plastic storage tubes, I like these tubes. And the end of the tube holes the bit nice and tight. I also REALLY like that they put a label on the tube, with the size, that is so nice. Ive reviewed quite a few router bits and its rare foe them to have any label on the tube, so hats off to this company. Great bit, great price, would recommend.

Ive been using this bit in my wooden sign making business and so far it works great and has remained sharp. Ive used it for 3d roughing passes in hardwood and in other applications where a ballnose bit is useful. So far, I havent noticed much difference in the quality of cuts from my more expensive bits. Its amazing to me that you can get quality tooling these days at this price point. These bits would make a great go to bit for production without having to stop to resharpen tooling. I would definitely recommend, and will order more!

Works great

Nice ball nose CNC router bit. Good quality. Clean, sharp cutting edges along entire flute.

TLDR: Duller than a bus trip to Branson. I Picked this downward-cutting end mill for some prototype packaging I wanted to develop using standard EVA foam. This endmill cut beautifully at 10K RPM for about ten pieces and then quickly began to dull. The CNC would continue to push the cutter through the foam, but the material would just flex and compress until the cutter passed leaving an inconsistent and wavy finish. This must be the lowest quality carbide they could source. I had to double-check the listing to ensure I didnt buy an HSS end mill by mistake. I am going to try to cut some aluminum or other harder material just to see if the other reviews for this product are fake. Id be shocked if it even cuts a chip given how poorly it wore doing something as simple as cutting foam.

This is an excellent bit that will help you to get the cnc results your after time and time again! Pros: 1. Excellent engineering minimizes chance of shearing 2. Bluing helps with rigidity and overall performance 3. Reasonably priced 4. Durable and long-lasting bit Cons: 1. The bit doesnt come with any markings, making identification more difficult when not in its case.

Great value and quality for this ball nose router bit. I have used this for a lot of roughing of 3d models in hardwood. Still sharp as the first time I used it.
