Value Collection 156400007000006 Combo Drill Countersink

Product Description

The VALUE COLLECTION 156400007000006 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 handles production drilling and countersinking in metal, wood, and composite materials. The 5/8-inch body diameter pairs with a 1/4-inch drill point, and the 6-inch overall length makes it well-suited for long-reach applications. The 60-degree included angle is standard for flat-head fastener seating. Machinists, toolmakers, and shop technicians are the primary users of this tool in both manual and CNC setups.

This combo drill countersink is used in general machining, fabrication shops, and maintenance environments where countersinking for flat-head screws and bolts is routine. The right-hand cut and plain cutting edge style make it compatible with standard drill presses, lathes, and milling machines. The double end type extends tool life by providing two usable ends. The long-length designation suits applications where standard-reach tooling cannot access the workpiece.

Installation Notes

This tool is installed and operated by machinists and toolroom technicians. Secure the shank firmly in the machine chuck or collet before operation and verify spindle speed is appropriate for the workpiece material before cutting. Always power down the machine and bring the spindle to a complete stop before changing or adjusting tooling. Wear appropriate eye protection and follow shop safety protocols when operating rotary cutting tools.
