YG-1 D1C90080 Combo Drill Countersink 1/16 Inch

Product Description

The YG-1 D1C90080 is a combination drill and countersink tool designed to perform two operations in a single pass. It drills a pilot hole and forms a countersink recess simultaneously, reducing setup time and tool changes on the workbench or in the field. Built to a 1/16 inch trade size with a bright uncoated finish, this tool is suited for light-duty drilling and countersinking in metal, wood, and composite materials. It is commonly used by electricians, HVAC technicians, and general tradespeople who need clean, flush-mount fastener seats without switching tools mid-task.

This combo drill countersink is intended for applications where a countersunk fastener seat is required before driving a flat-head screw. The 1/16 inch size is appropriate for small-diameter pilot holes in sheet metal, light structural steel, conduit hangers, brackets, and similar trade-work applications. It is sold individually and is compatible with standard drill chucks found on corded and cordless drill drivers.
