uxcell 5PCS 1/8" Shank 1.5mm x 12mm Carbide End Mill CNC Router Bits 2 Flute Milling Bit for Acrylic PVC MDF Wood

The 12mm cutter length is great for thicker stock. Be sure to move these slowly, as that extra length makes them very fragile. Broke a couple before I backed-off enough the motion speed. Still a good value IF you need 12mm. If you're not cutting that deep get a shorter cutter that's less fragile.

I am using the bits on a cnc to cut parts that have several small holes. These cut with little resulting waste and are sized so I dont have tool changes. Lost two bits from being stupid, but no loss from cutting.

I have some incredibly expensive end mills that I typically use for hardwoods, I'm not a fan of dulling out those $30 / end mill tools on things like "hardboard" or MDF - hence the $2.60 option. These have lasted a couple jobs per end mill using really conservative feeds and speeds ( 30 IPM, .65 mm depth per pass) and I can't complain. Don't buy these expecting them to last as long as your "Spektra" coated tools - expect them to be in the VALUE of $6.00 / tool for $2.60 each.

These bits are simply amazing. I was able to cut out 12 of these lanterns before 1 broke. I've got my cnc set to cut at 0.30 depth per pass and cutting 60 inches a minute turning 18000 rpms on the spindle. Extremely durable and cheap.

Easy of use

Poor quality. Leaves a rough finish. Tried all five pieces to get a hot job done but they just couldn't perform. Switched to a better brand and got a perfect finish.

Fast cutting sharp good value

Have not used these yet but they do appear well made. And product was as described.
