Review on Niagara Cutter N54021 Uncoated Finishing by Brendan Thorpe

I have this for cutting grooves in HDPE and wood framed slingshots. The cutter I had before didn't like HDPE, no matter the speed. I went to Karbid. The edges of this little bug are well formed. I didn't see any dull edges or uneven casting. The cutter works well on wood and Baltic birch plywood at high RPM and well on HDPE at very low RPM so molten plastic doesn't splatter all over the place. The beater doesn't pull material into the cutter like my old one did. He will pull it, but not snatch it from my hand. I recommend.
