Great bit, good price.

Great bit.Really good value for the price.

Good first impressions

I'm using these on a CNC to mill aspen. Aspen is a soft but fibrous wood. I was cutting with a slightly dull downcut bit, and though it was cutting with no issues it was leaving fuzz on the edges of the cut. Switching to these brand new bits fixed that.

very good bit

I use these to cut out letters for sings. They are leaps and bounds better than an upcut bit and better than a straight cut bit. Straight cut bits leave little burrs in plywood, upcut leaves a ton of burrs & makes it a nightmare to paint. These bits leave zero burrs on plywood (except at the bottom off the cut, easily sanded off). Downcut bits have to be fed slower on the CNC, BUT the longer working speed is by far worth it because you don't need to spend so much time sanding after the cut.
Will buy again if these ever dull down!!
