1-1/8″ Prestressed Concrete Wet Diamond Core Bit

The 1-1/8″ Prestressed Concrete Wet Diamond Core Bit is designed specifically for core drilling through prestressed and heavily reinforced concrete.

Crown Segments, Tight Gaps: Crown segment design with tight gaps keeps the bit stable in concrete with heavy rebar and prestressed strand, so you get a cleaner hole instead of wandering or hanging up on steel.

Soft-Bond Performance on Hard Concrete: Soft bond for speed continuously exposes fresh diamonds when the bit hits dense, high-PSI concrete and reinforcement — so it keeps drilling instead of glazing. Built for drilling hard concrete with heavy reinforcement.

• 1-1/8″ Outside Diameter: Precision-sized for cleaner holes.
• 14″ Overall Length
• 5/8″-11 Threaded Connection: Precision-machined works with standard commercial wet core rigs.
• Premium Soft-Bond Matrix: Formulated for speed in heavy reinforced and prestressed concrete — opens up to prevent segment glazing on steel in concrete.
• Removable Cap / Tube Extension Ready: Cap unscrews from the barrel for core removal and deeper drilling with added extensions.
• Wet Use Only: Optimized for water-cooled drilling to maximize footage and control dust on site.
