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)

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

Nice carbide router bit, leaves a great finish on all wood types. Stays sharp and cuts very well.

Im still kind of a newbie in the CNC Router arena, and while learning how to use the software thats needed to work with these machines, I am gradually building up my arsenal of bits so I can effectively use the machine. One thing I look for is bits that are made of solid carbide. They just keep their sharpness longer than high speed steel bits, so they run cooler and smoother longer. I also try to get bits that have a coating over the cutting area of the bits, as this also contribute to longer life and smoother cutting. I used this HQMaster 1/4 inch shank 1/8 inch cutting Ball Nose End Mill today as I was experimenting with 3-D carving. I created a simple half-torus model that I intended to carve, but was running into problems with the machine plunging deep into the wood before starting to carve the shape. It was supposed to start at the surface, but started probably 10 or 15 mm BELOW the surface instead. I never did figure out why it was doing this, and after a long period of trying I have up for the time being. BUT...I was amazed that this HGMaster bit still cut smoothly and evenly despite the fact that it was being forced to carve from a much deeper depth than it was supposed to. I let the program run a few minutes at this wrong depth before I shut it down, and observed the edges of the cuts - they were perfect, really nice and clean. Thats a great testament to the quality of this bit. Most bits can cut well when the machine isnt trying to power through a cut thats outside of its design parameters, but it takes a special one to be able to deal with it and do a good job anyway. Recommended!

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.

These inexpensive router bits are great. They cut well for my needs. Im not a professional that uses it everyday but for my occasional use it sharp and cuts clean. The ball upcut works great with my plunge router. Nice to be able to scribe lines in wood beauty panels. Quarter of the cost of premium bits.

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!

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.

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.

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

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.
