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)

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

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.

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.

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!

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

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 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.

The HQMaster 1/8 inch Ball Nose End Mill will be used to make a decorative edge on jewelry boxes. The bit was tested in Cherry wood and produced a perfect clean cut.

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

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.
