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)

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!

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

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.

While I would prefer a bearing bit (and I ordered one) this bit came within a few days of order and worked just fine for my needs. I needed to duplicate some Plexiglass objects and so set up the bit to travel along the original and cut the part out. My concern was burning the original (without having a bearing guide) but that was not the case and given the correct speed and movement speed this bit worked like a champ and stayed sharp for the duration of my project. I was cutting 1/4 Plexi and while I thought heat might be a problem it seemed to work just fine

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.

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.

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.

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.

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