SpeTool Upcut Spiral Router Bits Extra Long (4 inch) with 1/2 Inch Shank , 1/2 Cutting Diameter Solid Carbide CNC Router Bits End Mill for Wood Mortises and Cutting Dadoes Carving

Perfectly smooth and fast cut through 2 of Walnut

This bit is great! Made a sign out of 1.5 inch plywood 24x96 cut like a beast! Cut through a screw and it didn’t hurt it at all. This thing is a beast! Looking forward using this to make cabinets on the Cnc! I will buy this again.

Got this bit for a project that I needed to do a lot of mortise and tenons. Stayed sharp the whole time and worked great. Didnt dull at all, so I am assuming the longevity is good as well

Cut a 60” round table top out of buscuited 2x8’s Cut down about 1/2” per pass. Smooth cut, crisp edge. 5-stars

Nice sharp, make clean cut. with hand router i was able safe way to make 2 inch deep cuts

Unreal for dust extraction when used with festool of2200

Super smooth finish on my boards.

Absolutely loved this bit!

I needed this to cut mortices in red oak for a KS bed, see footboard leg in photo. In the picture you can see how effortlessly it cut into one of the hidden screws holding the 2x4s together to make the legs, there was no visible damage to the bit after cutting into 2 screws it completed the 16 mortices easily. Cut was silky smooth no chatter, finish was very clean.

Works great
