Review on Amana Carbide Spiral Plunge Up Cut Cutting Tools in Router Bits by Brett Kolpack

I use a bit to cut onto a 1/4 thick acrylic template and it works great but it turned out that the Cut below is better for my applications. I use a guide bush with a milling cutter over the workpiece and this bit pulls the chips up and they fuse together and make a mess. The cutting edge tip pushes chips out and down, reducing the amount of debris to be removed. The cut of this nozzle is very clean.
