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)

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.

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

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.

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.

Works great

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

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.

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!

This is a nice router bit to finish up details when coming close to the edges of a pattern line. Its well made and nicely machined. I would not use it to hog out material, but for detail work, I would recommend it.
