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.

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.

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.

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.

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.

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.

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.

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

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