Love Spetools
Size: 1PCS 1/4" Dia-1" CL-1/4" Shank
These are great for cutting acrylic and polycarbonate. You can’t beat the price, and unlike a lot of the no-name brands they have a tool database you can use with Fusion to quickly figure out the right feeds and speeds.

Tough to beat for the price.
Size: 5PCS 1/4" Dia-1" CL-1/4" Shank
A great single flute cutter for the money. I'm using it lightly for now, 1" DOC, .005 per flute at 7k RPM around a the outside of a 2-1/4" piece of round stock. Does a nice job and the final cut yields a diameter that matches G-code program with in a couple tenths. Will buy again!

Tip broke immediately
Size: 1PCS 1/16" Dia-3/8" CL-1/4" Shank
Bit broke within a couple minutes of use. Was trying to cut through 1/8” clear cast acrylic. 45 ipm feed rate, 30 ipm plunge, 16,000 rpm, .02 step down. Needed the bit to cut out plexiglass with some fine detail. Broke immediately upon start up of CNC. Wasted $30. Bought a well known named brand same size bit, ran the same settings it ran for 1.5 hours and completed the job. You get what you pay for. ... show more

Good bit but undersized 2.86mm / 0.1125in
Size: 1PCS 1/8" Dia-1/2" CL-1/4" Shank
The bit/coating are fine but as other reviews say the 1/8" bit is definitely undersized. I'll keep it but in the future I think I'll stick with the more expensive brands that actually give you the size they claim.

The right tool for the job!
Size: 1PCS 1/8" Dia-1/2" CL-1/4" Shank
Used this to cut a pick guard with my CNC for an electric guitar. It worked well and I didn't have any burning which was an issue with a standard end mill bit. Right tool for the job!

Excellent Quality
Size: 1PCS 1/8" Dia-1/2" CL-1/4" Shank
This worked great. The fine but allowed for detailed engraving. We bought extra just in case, though they lasted much longer than expected. High quality, would definitely buy again.
