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.

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.

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.

Quick tip: There is No 1/4 bit at a 2 cutting depth should be taken full-pass, unless its foam. Pretty much any bit at that side-load will stress and break at full depth. Easy pass depths and slow feed rates are the only hope. I consider this a specialty bit when working on deeper materials, just for the reach- never full depth. For XPS Foam (80% air), works great!

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

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.

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.

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