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)

The quality is fantastic and I use 1/4 more than any other and do tend to wear on them. These hold an edge well and have been put to great use cranking out holiday gifts. I cant think of an argument to pay more when this quality stands up to other really expensive options Ive tried. Update: This bit continues to hold an edge well after dozens of operations through hardwood at pretty aggressive settings of speeds. These are a fantastic workhorse bit to use.

Tested in mild steel. The cut was very smooth as the bit is very sharp. Should work well in many materials. After testing I used a 1/8 drill to check the size. The naked eye said it was a little large. Was it runout from my setup ? Bent bit ? Manufacturing defect? I checked with a micrometer and found the bit measured .126 Probably not a really big deal in most cases. I will call it a quality control issue. Or maybe when these are sent to us vine reviewers we get the ones that didn’t pass quality control. Might just be the perfect size for some project.

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.

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

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

Broke in 5 seconds at 50 ipm and 1/4 doc in mdf! Dont waste your money unless you plan on cutting for 10 hours at 1/16 depth of cut

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.

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.

Worked well even with a very high feed rate and stepover of about half the width using the entirety of the flute for quick roughing. Ran it for about 8 hours so far and it still feels very sharp.

Got this as a cheap alternative for my CNC for some relief carvings Ive been doing. It works well, havent seen any real issues so far. Im about 5-6 jobs in and still doing its thang so we will see how long it holds up. For now .. for the price ... Its definitely a good bit.
