Carbide bushings are appropriate for long-run high-production drilling applications.These higher-cost drill bushings are made of C2 tungsten carbide material for extreme wear resistance. PC bushings are the carbide version of our popular P bushings, which are permanently pressed into the jig plate, usually flush with the top surface. HC bushings are the carbide version of our popular H bushings, which are also permanently pressed into the jig plate and have a sturdy head to resist heavy axial loads. The head can be left exposed, or recessed by counterboring the installation hole. SFC bushings are the carbide version of our popular SF bushings, which are replaceable bushings generally used with a liner bushing and lockscrew. Other bushing types including Directed-Coolant Bushings, Gun-Drill Bushings, and special-to-print bushings are also available in carbide. All carbide bushings are manufactured to order.
