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

So far so good, had no problem to mortise through oak. Big question is how long will it stay sharp for? Good product for the buck.

The spiral cutter cuts smoother than straight cutters.

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

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

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.

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.

As described

Never owned one before but great cutter

Very impressed for the money

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.
