> 3 dayI ordered this for use in my CNC router. Had a production run of wooden pen cases to cut out (walnut and maple) and needed to order a new bit to avoid tearout. Took a chance on this one because the price was low. I wasnt expecting much, but its still very sharp after cutting for 12+ hours. Might be just a hair bigger than 1/4, as my 1/4 indexing pins were a little loose in the positioning holes that this bit drilled. Regardless, Ill order more of these for future jobs for sure. Very happy with the cut quality and tool life.

> 3 dayFirst time user of this product. Seems to work fine for my applications cutting wood and foam. Very sharp so use caution handling with bare hands.

> 3 dayBeen using this bit now for three months straight. I bought this one because it was cheaper than some other brand name options and didnt want to ruin a good bit due to my inexperience. This bit hasnt given me a reason to change yet. Cuts are baby smooth through any hardwood i throw at it!

Greater than one weekThis was purchased for cutting a radius through laminate plastic glued to MDF board used for shop made table saw miter sled. The down spiral cut left a very smooth, clean edge in the thin plastic, exactly as desired. It also left a clean, smooth edge on the MDF and a plastic liner glued to the underside as the surface contacting the table saw. If interested, this highly accurate miter build is illustrated by the designer on YouTube. Search for Making a Super Accurate Miter Gauge.

> 3 dayIve bought several sets of these CNC bits. We do a lot of profile cutting on a shop bot buddy. They cut cleanly and last quite a long time. And theyre much more affordable than the name brand bits. I havent had one break or prematurely wear out for reasons other than user error. Measure twice, cut once!
