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

Excellent router bit

Used it for cutting mortis joints, it worked as planned.

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.

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

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

Did not last long, Started to burn quick

The spiral cutter cuts smoother than straight cutters.

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.

This is a very adequate bit. Sharp, cuts are clean. As advertised. I use this in a plunge router to cut mortises in hardwoods and the results are quite satisfactory. Why pay more?

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