NEO TOOLS Extension for Diamond Core Bits 57-898, 355 mm, SDS-Plus to M16

Core bit extension for deep drilling in concrete, masonry, and stone. Extends reach by 355 mm, enabling access to hard-to-reach areas such as corners, ceilings, or behind obstacles. The SDS-Plus shank locks securely into rotary hammer drills, while the M16 thread accepts diamond core bits for precise, wobble-free operation.

Advantages
