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.

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

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.

Needed this to cut multi later birch plywood 1.5 thick. Just went down in 1/4 steps and it cut fine. Because of its long length just go slower than you usually would with a short bit . Longer bits tend to break if you apply too much force. Great bit for the price and cut better than I expected very clean edges.

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

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.

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.

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.

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.

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.
