Value Collection SC106012S Countersink Set 12 Pc Hss

Product Description

The VALUE COLLECTION SC106012S is a 12-piece countersink set designed for countersinking operations in metal, wood, and composite materials. Each countersink features a single flute, a 60-degree included angle, and a straight shank, making them compatible with standard drill chucks. The set spans a head diameter range of 3/16 inches to 2 inches, covering a wide variety of fastener sizes in a single kit. All cutters are manufactured from high-speed steel with a bright, uncoated finish and are ground for right-hand cutting. The set stores in a dedicated wood block for organized access at the workbench or job site.

This set suits machinists, millwrights, maintenance technicians, and woodworkers who need a broad range of countersink sizes on hand. It is well suited to production environments and general maintenance shops where matching countersink geometry to fastener head angle is a routine task. The 60-degree included angle is commonly specified for sheet metal and certain machine screw applications. Single-flute geometry helps reduce chatter and produces a cleaner finish in a variety of workpiece materials.

Installation Notes

Countersinks should be installed by a qualified machinist or tooling technician familiar with rotary cutting tools. Secure the workpiece firmly before operation and confirm the chuck or collet is tightened properly before starting the machine. Run at appropriate spindle speeds for the workpiece material — lower speeds are recommended for larger diameter cutters and harder materials. Inspect cutting edges before each use and remove from service any cutter showing chipping or excessive wear.
