Jogo de 5 fresas de 82° em aço rápido

The 82° angle gives a much cleaner chamfer than the 90° bits I was using before, no chatter at all. HSS steel holds an edge well through a whole afternoon of MDF work. Five sizes in one set means I'm not hunting for the right countersink mid-build.

Bought these mostly for countersinking screw holes in softwood and they cut fast without chattering. The high-speed steel holds an edge well, though I wish the case kept them from rolling around in my drawer.

The 82° angle cuts clean chamfers in softwood, but the flutes clog fast in aluminum and I have to stop and clear them constantly. Five pieces for the price is fair, though the smaller sizes feel a bit thin in the hand. Works well enough for occasional shop projects.
