SpeTool 14411 Ball Nose Carbide End Mill CNC Cutter Router Bits Double Flutes Spiral Milling Tool 1/4 inch Shank with 3 inch Over Length

I used this bit to put a radius on the bottom of a pocket that was roughed out with a flat bit on my CNC. It worked like a charm and Ill have to update after I put some more hours on it. Proper feeds and speeds are essential.

Fast shipping. Tool arrived quickly and sharp. For the 1/4” and above ball end mills, these guys make a reliable product.

Nice tool

I only needed to make one cur less than 1/2 in long. And the cut was easy in steel with a good finish. If you need to make 100 cuts buy one at five times the price.
