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

Works great

I was impressed with the results. Good quality and very sharp.

Great bit. Used it for a bunch of deep mortises in cherry and cuts like butter. Night and day going from straight bits to spiral. Feels much safer, more control and cleaner.

This worked fantastic. Good quality.

As described

I appreciate the extra cutting length for cutting mortises. I found it cut fast and clean in hard maple without burning. The upcut action means you dont have to constantly interrupt what youre doing to vacuum out the recess. At this price, its an excellent value.

Initial impressions are great. Will provide update after 6 months on durability. Made 12 mortises, so far nice results

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

Super smooth finish on my boards.

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.
