Vargus 154-00031 Countersink Set 4 Pc 3 Flute Hss

Product Description

The VARGUS 154-00031 is a 4-piece countersink set designed for chamfering and deburring operations in metal and general fabrication work. The set includes three countersinks and one deburring blade, covering a head diameter range of 1/2 inch to 13/16 inch. All cutting tools feature a 1/4-inch straight shank, 3-flute geometry, and a bright uncoated finish on high-speed steel construction. Right-hand cutting direction and single-end design make these tools straightforward to use in standard drill chucks and drivers. The set ships in a plastic storage case for organized tool storage on the job.

This countersink set is suited for machinists, fabricators, HVAC technicians, plumbers, and electricians who need to chamfer fastener holes or deburr cut edges in sheet metal, pipe, conduit, or structural components. The 1/2-inch to 13/16-inch hole diameter range covers common screw and bolt hole sizes found in residential and light commercial trade work. The included deburring blade extends the utility of the set beyond simple countersinking into general edge cleanup applications.

Installation Notes

Countersinks are typically installed and used by machinists, fabricators, and trade professionals working with metal sheet, conduit, or structural fastener holes. Secure the shank firmly in the drill chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Use appropriate eye protection and reduce spindle speed when countersinking harder materials. Inspect the cutting edges before use and replace or resharpen dull tools to maintain clean chamfer geometry.
