Value Collection 156400004000000 Drill Countersink No.4 Hss

Product Description

The VALUE COLLECTION 156400004000000 is a combination drill and countersink designed for creating pilot holes and countersunk seats in a single pass. Built from high-speed steel with a bright, uncoated finish, this tool accepts standard No. 4 screw sizes with a body diameter of 5/16 inches. The 1/8-inch drill point produces a clean entry hole while the 60-degree included angle forms the countersink in one operation. The double-end style maximizes tool life by providing two usable cutting ends. Overall length is 2-1/8 inches. Right-hand cutting direction suits standard drill chucks. Machinists, fabricators, and maintenance technicians use this tool in both production and field applications.

This combo drill countersink is suited for countersinking operations in metal fabrication, general machining, and maintenance repair work. The plain cutting edge style handles a range of workpiece materials common in trade and industrial settings. At 2-1/8 inches overall length, it fits standard drill press chucks and hand-held power drills. The No. 4 trade size targets fastener applications requiring a precisely sized pilot and countersink in one step, reducing setup time and tool changes on the bench or in the field.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard drill press or hand-held power drill. Secure the tool firmly in the chuck before operation and confirm the workpiece is clamped. Use appropriate cutting fluid for metal applications to extend tool life. Inspect both cutting ends before use and replace the tool if chipping or excessive wear is observed.
