C-43 Prestressed Wet Concrete & Asphalt

C-43 Prestressed Wet

The C43 Diamond Core Bit is great for hard asphalt and prestressed concrete. The pointed segments of the C43 feature the highest diamond concentration and slice through the toughest applications with blazing speed and remarkable life. The additional segments are closely spaced to fill in gaps for cutting: prestressed cables, loose rebar and loose wire mesh.

Use wet only. Sizes 2" to 18".

Core Travel: 14"

All C43's are threaded for a 1 1/4" - 7 adapter.
