Kodiak Cutting Tools KCT166406 USA Made Solid Carbide End Mill, AlTiN Coated, 4 Flute, 1/8" Diameter, 1/8" Shank, 1/2" Length of Cut, 1-1/2" Overall Length

Nice and sharp.

Bit broke milling aluminum :/

Kodak makes very good tools for hobbyists and GP items for pros. This is not as nice as their five-flute, but it's still good. The five flutes will finish an item smoother and cleaner, but the four is pretty standard, and will do a good job. I have noticed some brittleness in the carbide versions. So do be careful to lock down your material on the milling machine, first to ensure not only that you can cut it cleanly, but that you won't have vibrations that can shatter the thinner bits.

I'm new to CNC and have just built myself a small CNC Router. I didn't really know what to expect with these bits. These bits have exceeded my expectations! I made 5 clocks for Christmas presents and half a dozen of so other misc. projects. This things shows no sign of being even slightly dulled. Very happy! Very very sharp bit!

Nice Endmill, Worked great cutting 6061 aluminum! Would recommend.
