Review: Solid carbide bit - This is the first time I have used this brand. 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.
