Review on SpeTool 5Pcs/Set Flat Nose Double Flute Carbide End Mill 1/32" Cutting Dia Router Bits Cutter CNC Machine Tools For Carbon Steel Soft Alloy Steel Die Steel Tool Steel Cast Iron Wood by John Rivera

Revainrating 5 out of 5

Fine detail CNC router bit.

I like these bits. I just did a series of Celtic knot engravings in cherry wood with these bits using my Origin Shaper. I was pushing the bit speed to about 30,000 rpm. This bit cut through the cherry like it wasn't there. There was no damage to the bit and heating seemed minimal. As always, the cut depth per pass must be limited to the bit diameter. So it must be kept in mind that this bit cannot be expected to cut more than 1/16th of an inch deep per pass. To achieve appreciable depths of cut, greater than that, multiple passes must be made. Overall, so far, I am satisfied with these bits.
