PENETRATE DEEPER INTO REINFORCED CONCRETE AND MASONRY
When structural specifications demand deep-bore coring through thick slabs or multi-layered footings, standard bit lengths often fall short of the mark. This 12-inch SDS-MAX extension is engineered specifically for the high-torque environments of heavy civil and industrial jobsites. Designed to interface seamlessly with 5-inch and 6-inch thin wall core bits, this adapter maintains the necessary concentricity to prevent bit walking and ensure clean, efficient penetration through high-PSI concrete without overloading your rotary hammer’s transmission.
- / 12-Inch Extended Reach: Access tight or deep-set drilling areas where standard core bits cannot reach the required depth.
- / SDS-MAX Compatibility: Optimized for heavy-duty SDS-MAX rotary hammers, ensuring maximum energy transfer from the piston to the cutting edge.
- / Thin Wall Optimization: Specifically designed to support 5″ and 6″ thin wall core bits, reducing friction and heat buildup during prolonged use.
- / Industrial-Grade Steel: Forged to withstand the extreme rotational forces and impact energy found on large-scale infrastructure projects.
