Amana Spiral Plastic Cutting Down Cut Power & Hand Tools in Power Tool Parts & Accessories Review

Bought this bit to cut a groove in 5/16 inch thick HDPE plastic. Met my expectations. Bought another one as a replacement. Worth the money when you need sharp and accurate cutting. Remember that there are top cut bits and bottom cut bits. I tried the top cut bit first and it threw dirt in the direction I didn't want it to. In my application, the low cut bit worked better. i am satisfied
