Spline Fluted Core Bits with Rope Thread Shanks
Fluted Core Bits with Rope Thread Shanks – Spline
Fluted Core Bits with Rope Thread Shanks (Spline) 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.
This coring setup requires three components to operate properly: a fluted core bit cup, a rope thread spline shank, and a starter (pilot) bit. The starter bit ensures accurate initial penetration, while the rope thread shank securely connects the core bit to the hammer for stable operation and efficient energy transfer. The fluted core bit design helps clear debris during drilling, improving performance and hole quality.
Fluted core bits with rope thread shanks are ideal for applications requiring clean, precise openings for plumbing, electrical, HVAC, and mechanical installations. Their design supports controlled drilling and effective material removal, making them well-suited for jobsite use, renovations, and retrofit projects.
Manufactured from high-quality materials and engineered for durability, these three-piece system components are built to withstand the impact and rotational forces of heavy-duty drilling in demanding concrete and masonry environments. Their rugged construction helps maintain cutting efficiency and consistent performance over time.
Designed to deliver reliable drilling results, accurate hole placement, and secure component connection when properly assembled and matched to your hammer, spline fluted core bit systems are a dependable solution for contractors, installers, utility crews, and rental centers handling large-diameter coring applications.
