Champion 798 Combined Drill & Countersink — Heavy-Duty One-Pass Drilling and Countersinking

The Champion 798 Combined Drill & Countersink is a professional-grade combination tool designed to drill and countersink in a single operation for flat-head fasteners. Engineered for efficiency and repeatability, the 798 series eliminates secondary countersinking steps while ensuring perfect alignment between the drilled hole and the countersink.

Manufactured from high-speed steel (HSS), Champion 798 tools feature a robust drill point combined with a precision-ground countersink body, making them well suited for production, fabrication, and maintenance environments. Compared to lighter-duty combination tools, the 798 series is designed for more demanding applications where durability, consistency, and tool life are critical.

The integrated design guarantees concentricity, improves appearance, and significantly reduces cycle time, making the Champion 798 an excellent choice for repetitive drilling and fastening operations.
