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

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

Unreal for dust extraction when used with festool of2200

Using this on my CNC lathe. Works great. So sharp you need to be careful just handling the bit. (Voice of experience.)

Worked well for cutting my tabletop.

Initially it was great but if felt like it got dull pretty quickly. Overall it’s still pretty sharp, but the tip is what’s used the most is dull. If they can add some kind of coating just on the tip it will greatly benefit its life. But I also have a WhiteSide brand tool and I feel like it lasts longer.

Run in a commercial shop on a CNC router in walnut and Oak. This thing performs better than the big names like whiteside, freud etc and at half the cost. Its so sharp its virtually silent. Very impressed.

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.

Used this on a recent desk project. Using several passes with this bit I was able to get nice clean cuts. The bit is very sharp so handling with care is needed.

The spiral cutter cuts smoother than straight cutters.

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