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

Very high quality was not disappointed. I use it for making maloof joints and making the first notch. Could not recommend it enough.

Great stuff. Gets the job done for sure.

Crazy smooth cut on 1.5 inch Corian edge. Makes old 2 flute bits seem like the dark ages.

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.

I been using this router bit for years, like the quality and the price, will be buying the same in a regular basis

Produced an extremely clean cut without burning or tear out.

I purchased for a friend. He said that it worked great and that the price was good.

Cut maple end grain counter top like butter. Very little tear out, very sharp - only used it a few times but appears to stay very sharp with repeated use - time will tell. Based on price - I couldnt ask for more!

Perfectly smooth and fast cut through 2 of Walnut

Solid bit that cuts smoothly with little splintering. Didnt perform as well as Id hope with plywood but Im sure Ill be using this bit often in the future.
