Product Description

Best used for: Standard milling, dadoing, and boring. Cutting Diameter: 1/8" Cutting Height: 1/2" Shank Diameter: 1/4" Overall Length: 2" Flutes: 2 Up-cut end mills direct woodchips up and away from the milling area leaving an unobstructed path for the end mill. Bit breakage is less likely. Up cut end mills are the best choice for most standard milling applications. The up cut direction can leave behind a minimally rough top surface edge.

Cut Aztec PVC sheet like butter!

Cut Aztec PVC sheet like butter!
I needed a cutter that would cut PVC in a hand held Dewalt router and after some searching i decided to try the Yonico 31215-SC. I noticed a few cutter specifically made for plastic but was advised not to use them in a hand held router as they only had one cutting edge / flute and are ideally suited to a CNC machines. I needed these urgently and as usual Amazon Prime delivered in just two days. I set up a template and with these new bits started cutting the 1/4" thick Aztec PVC sheet. They worked like a dream, by keeping the router speed quite low and moving the router slowly i was able to cut out 12 x 6" dust collection support brackets in just 30 minutes. At a material cost of just $12 i was able to save more than $300 on shop brought brackets. Well worth the cost.

1.0 out of 5 stars Broke on First Use / Don't waste your time.
Reviewed in the United States on July 8, 2023
Bit broke on a really easy cut... was just cutting soft pine wood. Was only driving it at 120 Inch/min, and cutting depth passes of only 0.130 inches. The break looks like the steel wasn't properly hardened during manufacturing.
