Value Collection SC20901210S Countersink Set 10 Pc Hss

Product Description

The VALUE COLLECTION SC20901210S is a 10-piece countersink set engineered for professional countersinking operations in metal, wood, and composite materials. The set covers a head diameter range of 3/16 inches to 1-1/4 inches, giving technicians and machinists the flexibility to match a wide variety of fastener sizes in a single kit. Each countersink features 6 flutes and a 90-degree included angle with a 45-degree centerline angle, producing clean, accurate seat profiles. Tools are manufactured from high-speed steel with a bright, uncoated finish. A wood storage block keeps all 10 pieces organized and accessible at the bench or on the job.

This set is suited for metalworking shops, fabrication facilities, maintenance and repair operations, and production environments where multiple countersink sizes are needed on a regular basis. The straight shank design is compatible with standard drill press chucks and hand drill drivers. Right-hand cutting direction makes these tools appropriate for conventional drilling setups. The included wood block provides organized storage between uses and is practical for both fixed shop environments and portable tool kits.

Installation Notes

Countersinks should be installed by machinists or skilled tradespeople familiar with rotary cutting tools. Secure the straight shank firmly in the chuck before operation and confirm the workpiece is clamped to prevent movement. Use appropriate cutting speeds for the workpiece material — higher speeds for softer materials, reduced speeds for harder metals. Inspect each tool for wear or damage before use and never force a dull countersink through material.
