Value Collection 156400007000000 Drill Countersink Size 7

Product Description

The VALUE COLLECTION 156400007000000 is a combination drill and countersink tool designed to drill a pilot hole and countersink in a single pass. Made from high-speed steel with a bright, uncoated finish, this tool handles both operations without a tool change. The body diameter is 0.625 inches, the drill point diameter is 0.25 inches, and the overall length is 3.25 inches. It is suited for metalworking, woodworking, and general fabrication applications where flat-head fasteners must sit flush with or below the material surface. Licensed machinists, pipefitters, and general tradespeople use this tool on a regular basis.

This combo drill countersink is a trade size 7 tool with a plain cutting edge style and a 60-degree included angle. The right-hand cutting direction matches standard drill press and hand drill rotation. The double-end style provides extended tool life. It is appropriate for use in shops, fabrication facilities, and on-site work where countersinking is a routine operation on ferrous and non-ferrous materials.

Installation Notes

A licensed machinist or qualified tradesperson should secure the workpiece firmly before drilling to prevent movement. Use appropriate cutting fluid when working with ferrous metals to extend tool life and improve cut quality. Ensure the drill press or hand drill is fully stopped before changing or inspecting the tool. Follow applicable shop safety standards and wear proper eye protection during all cutting operations.
