Value Collection 156400003000004 Drill Countersink Hss

Product Description

The VALUE COLLECTION 156400003000004 is a combination drill and countersink tool designed for creating countersunk pilot holes in a single pass. Built from high-speed steel (HSS) with a bright, uncoated finish, this tool handles both drilling and countersinking in one operation, reducing setup time and tool changes. It features a 1/4 inch body diameter, a 7/64 inch drill point diameter, a 60-degree included angle, and a 4 inch overall length. The double-end design extends tool life by providing two usable cutting ends. Right-hand cut geometry is standard for conventional drill press and hand-held drill operation. Machinists, fabricators, and maintenance technicians working with wood, plastics, and soft metals will find this tool suited to standard countersinking tasks.

This combo drill countersink is used in general machining, fabrication, and maintenance applications where a countersunk screw seat is required. The trade size 3 designation and plain cutting edge style make it a straightforward fit for bench drill presses, CNC drilling operations, and portable drill applications. It is a long-length tool suitable for applications requiring extended reach. The 7/64 inch drill point length provides controlled entry before the countersink angle engages the workpiece.

Compatibility

Designed as a standard combination drill countersink for use in drill presses, CNC equipment, and hand-held drills accepting 1/4 inch body diameter tooling with right-hand cut geometry.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard drill chucks that accept a 1/4 inch shank. Secure the tool firmly in the chuck before operation and verify that the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or lubrication when working with metals to reduce heat buildup and extend tool life. Inspect both cutting ends for wear or chipping before use and replace the tool if the cutting edge is damaged.
