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

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

Went to make a test cut on a half inch thick piece of wood and the bit snapped within 30 seconds.

I have never used a bit this long before. I was having some problems controlling it. I suspect control would come with time.

Bought this bit for my circle jig and it did not last at all. Got about half ways of a circle (17”) and it snapped.

Managed to cut out 21 pieces for a custom order of corbels. Had to do conservative cuts due to the length of the bit but was able to complete all the cuts with just one bit. 33 in/min, 18k spindle speed, .125 depth of cut.

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