Carbide drills provide faster cutting rates, longer tool life, better positional and dimensional accuracy, and improved surface finish. Stntools solid carbide drills are manufactured from Sumitomo carbide grades and the tools are produced by our carbide production facility in Taiwan. The carbide drill bits are used industrially for materials such as cast iron, heavy metal nonferrous, stainless steel, and other abrasive materials.

Carbide drill bits have a strong working advantage over HSS drills & Cobalt drills and are operated more effectively by absorbing heat at greater speeds. In shallow holes, a tipped carbide drill is efficient and costs less than half a solid carbide drill bit. If deeper holes are drilled, solid carbide drills work very well, and coolant fed drills work even better. However, to use this style, a VMC machine with coolant supply is necessary. With AlTin coating our coolant fed carbide drills are standard to order and achieve a very low cost per component
