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)

Skip it, buy a higher quality bit and save the headache.

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.

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.

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

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.

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 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.

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.

Nice ball nose CNC router bit. Good quality. Clean, sharp cutting edges along entire flute.

This is a nice quality router bit. It is very sharp and works as its supposed to. It is packaged very nicely. It comes in the standard router bit square plastic case. The great thing here is that the case is labeled very clearly, so you dont have to squint (or get a magnifying glass) to read the side of the shank. This is very useful as you are juggling different bits and needing to match the right bits to the right tool paths. I use these bits on my CNC to carve designs into soft woods. So far, so good, the bit is still in once piece. I am very happy with the performance and the results of this bit.
