Value Collection SC218210S Countersink Set 10 Pc Cobalt Steel

Product Description

The VALUE COLLECTION SC218210S is a 10-piece cobalt steel countersink set designed for countersinking operations across a range of fastener head sizes. The set covers a minimum head diameter of 3/16 inches through a maximum of 1-1/4 inches, with a fixed 82-degree included angle suited to standard flat-head fastener geometry. Each countersink features 6 flutes and a straight shank, providing clean cutting action and consistent seating depth. The bright, uncoated finish on cobalt steel construction offers good hardness and heat resistance for use in ferrous and non-ferrous materials. The 10 pieces store in an included wood block for organized access at the bench or on the job.

This set is suited for machine shops, fabrication environments, and maintenance trades where flat-head screws and bolts must be seated flush with the workpiece surface. The 82-degree angle matches the geometry of most standard flat-head machine screws used in metalworking applications. Right-hand cutting direction makes these countersinks compatible with conventional drill press and hand-drill operation. The range from 3/16 inches to 1-1/4 inches covers the majority of common fastener head sizes encountered in general machining and assembly work.

Key Features

• 10-piece set spanning 3/16 inches to 1-1/4 inches head diameter
• 82-degree included angle for standard flat-head fastener compatibility
• 6-flute design for smooth, chatter-reduced cutting
• Cobalt steel construction for elevated hardness and heat resistance
• Straight shank fits standard drill chucks and drill press spindles
• Wood block storage keeps all 10 pieces organized and protected

Compatibility

Designed as a general-purpose countersink set for use with standard straight-shank drill chucks in drill press, lathe, and hand-drill applications where an 82-degree countersink profile is required.

Installation Notes

Countersinks are typically installed and operated by machinists, fabricators, and maintenance mechanics. Secure the workpiece firmly before operation and run at appropriate spindle speeds for the material being cut. Inspect each countersink for wear or chipping before use. Store in the provided wood block to protect cutting edges between uses.
