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 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.

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.

HQMaster’s 1/8-inch carbide ball nose end mill with nano blue coating and 1/4-shaft is a well-made and sharp bit. The nano blue coating improves the heat performance of the bit, and the 1/4-shaft adds rigidity. Both features will increase the life of the end mill. The bit comes packaged in a typical rectangular plastic box. The bit itself comes without any markings on it shaft. I much prefer that the end mill be labelled to allow easy identification and to prevent tool mix-ups. This is a good workhorse type end mill that I will find a lot of use for.

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.

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.

Skip it, buy a higher quality bit and save the headache.

Good bit, does what I need it to do and worth the price, will buy more in the future.

I bought the 1/8” cutting diameter bit, and used it with my router and DIY circle jig to cut a perfect, 11” diameter circle in 1/2” plywood. The down cut left no splinters on the top side of the plywood, and very few on the bottom side. I do not know how long it will last, but it worked very well on its maiden voyage.

This is 1/4 inch Shank, 1/8 inch cutting Ball Nose End Mill CNC router bit with Nano Blue Coating. Its a Spiral CNC Bit for Wood Cut, Carving, or Engraving. Im using it in my CNC machine for wood carving. Its being used in a Makita Trim Router and it works very well. Ive used it on a few projects now and they look good with just a little sanding. Nice bit.

I made a test cut with this bit on a piece of Gaboon Ebony to see how it fared. It cut clean and held its edge even on that brutal wood, albeit I only ran about 12in/305mm. Being coated carbide, I expect that itll hold up well if it made it through that first run without immediate dulling. As with any router bit, RPM and feed speed are critical in getting the best results. I ran this at 25,000 rpm on my router table and fed the workpiece by hand, feeling for the proper speed. Only experience can guide you if youre feeding it by hand. If youre fortunate enough to have a CNC, follow the appropriate guidelines for the material youre cutting for best results.
