SpeTool Spiral Router Bits with UpCut 4 inch Extra Long1/4 inch Cutting Diameter 2 inch Cutting Length CNC Router Bit Carving Tool

This tool is a great way to get your idea onto a piece of wood and make it look great.

Even taking very shallow cuts (~ 1/8) this bit did nothing but chatter. This left a horrible shoulder on my mortise. I switched to using a shorter bit from whiteside for the first portion of the cut, and it cut like butter. I am glad this mortise will be hidden, because otherwise this bit would have ruined my project.

I needed something with some length so I can use with my router and templates and this works great

I needed this to CNC 1.75 inch thick glue up panels. At the time of this review probably have 100 hours on this but and its still working as well as the first day I used it.

Use in my cnc for 1.5 inch pine and while cutting multiple passes all stayed aligned.

This was much sharper and much more high quality than anticipated for the price. Ive used it now to cut several table tops with a router jig and it performed flawlessly.
