SDS-plus bits use an asymmetrical-parabolic flute for efficient energy transmission and dust removal.
Simpson Strong-Tie core bits are made to the same exacting standards as our standard carbide-tipped drill bits. They utilize a centering bit to facilitate accurate drilling in combination hammer/drill mode.
Note: With 1-piece bits, once coring is begun, the centering bit must be removed using ejector pin. Core bit bodies are 2 11⁄16" deep.
