Value Collection 156400003000006 Drill Countersink Hss

Product Description

The VALUE COLLECTION 156400003000006 is a combination drill and countersink tool designed for creating pilot holes and countersunk seats in a single operation. Machined from high-speed steel with a bright, uncoated finish, this tool features a 1/4-inch body diameter and a 7/64-inch drill point diameter. The 60-degree included angle and right-hand cutting direction make it well-suited for standard countersinking applications in metal, wood, and composite materials. At 6 inches overall length, it qualifies as a long-length tool, offering added reach in confined or deep-clearance setups. The plain cutting edge style and double end type provide clean, accurate results with minimal setup.

This combo drill countersink is used in general machining, fabrication, and maintenance applications where a countersunk fastener seat is required. Trade Size 3 indicates the standard sizing designation for this tool family. It is appropriate for use in job-shop environments, maintenance and repair operations, and production settings where both drilling and countersinking need to be completed without a tool change. It is not aircraft-style and is not tapered, making it a straightforward choice for conventional countersinking tasks.

Compatibility

Designed as a standard combo drill countersink for use in conventional drilling and countersinking applications where a Trade Size 3, 1/4-inch body diameter tool is specified.

Installation Notes

This tool is installed in a compatible drill chuck or milling machine collet by a machinist or qualified tradesperson. Secure the workpiece firmly before operation and confirm the spindle rotation matches the right-hand cutting direction. Power down all equipment completely before changing or inspecting the tool. Follow applicable shop safety standards and manufacturer guidance for feed rate and speed selection based on workpiece material.
