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)

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.

This cutter is dimensionally accurate according to my caliper. That is good as sometimes 6mm shank are sold as 1/4 (6.35mm). Under magnification the ball end is smooth without burrs. It is only 2-flute so I wouldnt try to cut metal with it but wood and plastic should be fine.

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

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 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

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.

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

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

Works great

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!
