SpeTool Single Flute Aluminium Router Bits 1/4 Shank Tungsten Carbide Spiral O Flute End Mill 1/8" Cutting Diameter with TAC Coating CNC Router Bits Router Cutters Milling Bits for Wood Aluminum

These SpeTool bits are superb. They are cut beautifully. Durability is hard to determine quickly, but I'm very happy. There are speeds and feeds available on their website. For the novice CNC'er, I can't think of a better tool brand to invest in.

A great single flute cutter for the money. I'm using it lightly for now, 1" DOC, .005 per flute at 7k RPM around a the outside of a 2-1/4" piece of round stock. Does a nice job and the final cut yields a diameter that matches G-code program with in a couple tenths. Will buy again!

I cut parts in T6061-T6 Aluminum on my MK2 CNC for brake spacers. Clean, easy cuts. Just take small passes. Spe-tool never disappoints.

Love this bit.

I needed to rout a channel in hardwood for the wire of a cheese slicer that I was making. In the past I used a table saw but I no longer have one

You can never have too many good bits!
