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

This is a nice quality bit, very sharp.

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

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

Very sharp. Just what I wanted.

I use this bit for edge jointing on my router table. Its incredible, if youre on the fence you should give this a try.

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!

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.

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

Excellent edge quality and sharpness. No problem routing 1 3/4 depth red oak with no deflection.

Did not last long, Started to burn quick
