Sharp.
Well made, allowed me to try free hand sign routing. Good for outlining design when routing.

Great for milling SRBP PCBs and good value in my opinion
I've milled several PCBs without breaking one and it's still sharp. I find the 30deg angle better than the 20deg as it gives that little bit extra width to the cut. I didn't have much success with cheap 20deg ones.

Ok quality but use coolant for engraving metal
The media could not be loaded. Ok quality for the money, I use them for engraving anodised aluminium, but you must use a coolant as cheap grade metals stick to the cutter and break the tips, I used a paste and it works a treat but I also tried heavy oil which worked great too but a bit more messyI only did 0.2mm depth for the engraving and used 500mm/m feed and 200mm/m plunge

Perfectly compatible v carve bits
Perfect for the genmitsu 3018 I have. Done a few scarves with them. Make a nice clean cut as long as you go slow (since they're a single flute design)

Not carbide and not very sharp
The headline description of these says 'carbide' but I see in the description that they're made of alloy steel. This fits with my experience of trying to use them for metal engraving (aluminium) - They aren't very sharp and haven't got a good enough edge to cut metal. Probably OK for wood & plastic. Would not buy again.

A good product
I bought these bits for engraving acrylic , and they worked extremely well.

Better than other reviews may suggest?
First time using a small CNC for work in brass, and these cutters were a bit of a gamble given other reviews. Yes, I broke the first one I tried but that was down to me not getting the calibration right on my machine (WCS vs MCS, doh!) The next run was great though.

Ok quality, but very different lenght and shape. Bit converning for a milling tool. Will buy different next time.
