Needed to mill and shape a hard plaster of paris material which can be quite difficult to achieve a good finish using HSS These Carbide tools worked perfectly, were delivered quickly - excellent service
I have just completed a couple of intricate items, with 1/3of the time cutting out with XY cuts up to 3 mm, and the rest of the project pocketing, often at full 6mm width, though only 1.2mm z advances. I used plenty of fluid. The results were excellent, and the cutter life was double that obtained from what until now was my cutter of choice, which cost almost twice as much. Incidentally, the service from shop-apt has been exemplary
