AT Combined Drill & Countersinks
AT combined drill countersinks—often called drill countersink bits or combination drill & countersink tools—are designed to streamline hole preparation by drilling a pilot hole and creating a chamfer/countersink in one operation (application dependent). They’re commonly used in fabrication and maintenance work to help reduce tool changes and produce cleaner, more consistent hole edges for fasteners, rivets, and general deburring.
