Product Overview
The double-pointed segments of the C-51 Diamond Core Bit provide incredibly great drilling speeds in concrete. The C-51 bit has high quality diamonds that are ideal for cutting concrete with rebar. By spacing the segments further apart, the C-51 drills more aggressively in hard materials like concrete and granite. The double-pointed segment tips penetrate quickly, hold a straight drilling path by reducing side drag, increase water flow to reduce heat, and remove slurry more efficiently.
These bits are specially formulated for hard aggregate (river rock/granite) and heavy steel.
Use wet only. Bits 3/8" to 1-3/4" are crowned (no double-pointed segments). Bits 1-7/8" and larger are segmented.
Core Travel: 14" for bits up to 14" in diameter, 20" for 16" and 18" diameter bits, and 24" for 20" and 24" in diameter bit.
C51's that are 1-1/2" and smaller are threaded for a 5/8"-11 spindle. C51's 1-5/8" and larger are threaded for a 1-1/4" - 7 spindle.
