Value Collection 156400004000005 Drill Countersink Sz4

Product Description

The VALUE COLLECTION 156400004000005 is a combo drill countersink designed for simultaneous drilling and countersinking in a single pass. Built from high-speed steel (HSS) with a bright, uncoated finish, this tool handles ferrous and non-ferrous materials in production and maintenance environments. The 60-degree included angle produces a clean countersink seat suited for flat-head fastener installation. At 5 inches overall length, it qualifies as a long-length tool, providing reach in deeper or recessed workpieces. The double-end configuration extends usable tool life by offering two cutting ends before replacement is needed. Installation is performed by machinists, tool-and-die technicians, and general maintenance trade professionals.

This combo drill countersink is suited for countersinking applications in metal fabrication, maintenance repair, and general machine shop work. It accepts a right-hand cutting direction and features a plain cutting edge style with no insertable cutter head and a non-tapered body. The 1/8-inch point diameter allows it to start in pre-drilled or self-started locations. Typical applications include preparing holes for flat-head screws and bolts in metal plate and structural stock. It is not configured for aircraft-style applications.

Installation Notes

Machinists and maintenance technicians should secure the tool in a compatible drill press or hand drill chuck rated for the shank diameter before use. Power down and de-energize all equipment before changing or inspecting cutting tools. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Follow shop safety standards and applicable OSHA guidelines when operating rotating cutting tools.
