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

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

This bit has served me well, use it on my cnc router. The price is very cheap for bits but the quality is there.

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.

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.

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

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.

Worked great on the 1 1/2 inch mdf. Got the done. After the job the operator tried it on some 1 1/2 inch oak with out changing speed/feed. He got 2 of the 6 3/4 thru holes before the bit snapped.

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

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

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.
