Value Collection 156400008000000 Combo Drill Countersink Size 8

Product Description

The VALUE COLLECTION 156400008000000 is a combination drill and countersink designed to drill a pilot hole and form a countersink seat in a single pass. Built from high-speed steel with a bright, uncoated finish, this tool handles wood, plastics, and softer metals without a separate tool change. The trade size 8 configuration pairs a 5/16-inch drill point with a 60-degree included angle countersink, producing clean, consistent seats for flat-head fasteners. Overall length is 3.5 inches with a 0.75-inch body diameter. It is suited for bench-top drill press work or hand-drill use by carpenters, millwrights, and general tradespeople.

This combo drill countersink is used in light fabrication, cabinetry, fixture mounting, and general mechanical assembly where countersunk fastener holes are required. The right-hand cutting direction and plain cutting edge style make it compatible with standard drill chucks and drill presses found in trade and production shop environments. The double-end type design extends usable tool life. No insertable cutter head or taper is present, keeping the setup simple for repetitive countersinking tasks in moderate-volume applications.

Installation Notes

Installation is performed by qualified tradespeople using a drill press or hand drill with an appropriate chuck size. Secure the workpiece firmly before drilling to prevent movement during the cutting operation. Inspect the cutting edges before use and replace the tool if chipping or dullness is observed. Follow shop safety practices including eye protection when operating rotary cutting tools.
