Spline Coring Cup Systems
Spline Coring Cup Systems
Spline Coring Cup Systems are designed for drilling large-diameter holes in concrete, masonry, and block when used with spline-drive rotary hammers. Before selecting components, be sure to reference the Chisel Lookup by Hammer tool at the top of this page to confirm compatibility with your specific spline hammer.
Each coring system requires three components to operate properly: a core bit cup, a spline shank, and a starter (pilot) bit. These components work together to provide accurate starts, stable drilling, and efficient material removal. The starter bit guides the system during initial penetration, while the spline shank securely connects the core bit assembly to the hammer for effective energy transfer.
Spline coring cup systems are ideal for applications that require clean, precise openings for plumbing, electrical, HVAC, and mechanical installations. Whether using fluted or thin wall core bits, these systems allow operators to drill efficiently while maintaining control and hole accuracy on demanding jobsite applications.
Manufactured from high-quality materials and engineered for durability, spline coring system components are built to withstand the combined impact and rotational forces involved in heavy-duty drilling. Their rugged construction helps maintain cutting efficiency and consistent performance in challenging concrete and masonry environments.
Designed to deliver reliable drilling results, accurate hole placement, and secure component connection when properly assembled and matched to your hammer, spline coring cup systems are a dependable solution for contractors, installers, utility crews, and rental centers handling large-diameter coring work.
