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

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.

I like it

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

Perfectly smooth and fast cut through 2 of Walnut

Used it only once thus far. Cutting 2 cherry. Very sharp, low noise, low vibration. Good enough for me.

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 is a nice quality bit, very sharp.

Super sharp and very accurate. Ive been using it to cut deep mortises in 4x4s. Flawless cuts.

I purchased cutter to machine mortises, really pleased with finish.

The overall quality is excellent and it cuts Baltic birch plywood very well.
