Enhanced Cutting Power: 4Fl SE Carbide End Mill Cutting Tools for Precision Machining Review

May be suitable for wood but will not stand up to aluminum even with very light passes. Leaves scratches when sticking. Can handle a face-to-face pass no deeper than 0.001 inch.

Nice and sharp, works great on 16ga aluminum sheet in a dremel. Bought 2 used 1 still razor sharp. I recommend them to everyone

Worked PERFECTLY for milling 6061 Aluminum on my CNC. Cuts through like butter. Great for the price, will definitely buy another if this ever needs replacing.

Nice detail. It seemed to work better than some of the cheaper cutters I've used with my Dremel. However, I had a problem protecting them. The racquet will come loose after some use and may fly out, which is very dangerous. I'm not sure if it's the bit or if my dremel bit has a bad grip.

Good nozzle. It seems to work better than some of the cheaper bits I've used with my Dremel. However, I had trouble installing it. It can fly out after some use, which is very dangerous I'm not sure if it's a bit or my dremel bit isn't holding up well.
