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

Worked great. Used it to cut sink opening in butcher block counter.

Absolutely loved this bit!

The router bits, 1/2 inch, are not compatible with the makita, the shank is too large and does not enter, measured by the digital gauge, from a measurement of about 12.65 mm.

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

Never owned one before but great cutter

Clean smooth cut grooving in hard maple @ 23000 RPM. Good quality bit.

This bit cuts so clean I am very impressed.

The spiral cutter cuts smoother than straight cutters.

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.

This worked fantastic. Good quality.
