SpeTool Spiral Router Bits Down Cut 1/4 inch Cutting Diameter, 1/4 inch Shank Solid Carbide CNC Bits End Mill for Wood Cut Carving Engraver

sharp clean cuts, appears to last through numerous projects though i don't subject it to that many

I bought this to use on my CNC machine for making flags and signs. It cuts very well and continues to do so after many cuts. The price is great and the quality is even better.

Great Drill bit. I used for CNC Shopbot and it worked great.

Good endmills. Plain, uncoated metal, but they're packaged well and they're sharp enough to slice your finger (...so I've heard...)Good price for what they are, too. The lack of coating means they get dirty quicker, though.

these are very good bits

The down cut spiral router bit leaves a nice clean top edge. I'm using it in a handheld plunge router with a circle jig to cut holes and recesses in DIY speaker boxes. I don't really have anything else to compare it to but it seems to be sharp, decent quality and cuts smooth. I cannot comment on how long it stays sharp because I've only used it a few times.

These are great bits. They hold their edge well after hours of use.

This 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.
