Value Collection 156400004120004 Drill Countersink Hss

Product Description

The VALUE COLLECTION 156400004120004 is a combination drill and countersink designed for creating pilot holes and countersunk seats in a single operation. Built from high-speed steel with a bright, uncoated finish, this tool handles both drilling and countersinking without requiring a tool change. The 3/8-inch body diameter and 4-inch overall length place it in the long-length category, making it well suited for deeper reach applications. The 60-degree included angle produces a standard countersink profile. Right-hand cutting direction and a plain cutting edge style make this a straightforward, general-purpose tool for metal fabrication and assembly work.

This combo drill countersink is appropriate for shop and field use in metal working environments where countersinking is a routine operation. The double end type extends tool life by providing two usable ends. Typical applications include deburring, fastener seat preparation, and pilot hole drilling in steel and other ferrous materials. Machinists, fabricators, and maintenance technicians are the primary users. The trade size 4-1/2 designation identifies the countersink size within standard sizing conventions used across the trade.
