Value Collection 156400003000005 Drill Countersink Hss

Product Description

The VALUE COLLECTION 156400003000005 is a combination drill and countersink tool designed to drill a pilot hole and form a countersink in a single operation. Built from high-speed steel with a bright, uncoated finish, this tool features a No. 3 trade size with a 0.25-inch body diameter and a 7/64-inch drill point diameter. The 60-degree included angle produces a clean, standard countersink profile suitable for flat-head fasteners. At 5 inches overall length, it falls into the long-length category. It is installed by machinists, fabricators, and maintenance technicians working in metal fabrication, woodworking, and general manufacturing environments.

This combo drill countersink is suited for countersinking operations on a wide range of materials where a standard 60-degree seat angle is required. The right-hand cutting direction is compatible with conventional drill press and hand-drill setups. The double end type and plain cutting edge style make it a straightforward choice for production and repair work where a combined drilling and countersinking step reduces setup time and tooling changes.

Installation Notes

This tool is installed by machinists and fabrication technicians. Secure the workpiece firmly before operation and ensure the tool is properly seated and tightened in the chuck or collet before starting. Power down the machine completely before changing or inspecting the tool. Do not exceed the rated speed range for high-speed steel tooling in the material being cut, and apply appropriate cutting fluid when machining metals to extend tool life.
