So far seem to be high quality with sharp cutting edges. Used with CNC machine with good expected results. Review: The customer service is awesome - My delivery didn’t make it on the first one I ordered so they resent it. It got here 4 days after order. Due to the fast acting customer service. I will order more bits from them. Weather these bits last or not because I go through bits. But to me the customer service outshines any dullness of a bit. These seem to be very good quality only time will tell. But worth every penny I paid and then some. ## Features - This 2 flute round nose endmill has a cutting diameter of 1/4" and a cutting length of 3/4".
