Value Collection 28606 Countersink 3/4 in 82 Deg 1 Flute Hss

Product Description

The VALUE COLLECTION 28606 is a single-flute countersink designed for creating conical recesses in metal, wood, and composite materials to seat flat-head fasteners flush with or below the work surface. Built from high speed steel, it delivers heat resistance and edge retention suited to production and maintenance drilling environments. The 82-degree included angle matches the standard for flat-head machine screws and sheet metal fasteners used in general fabrication and assembly work. The 1/2-inch shank fits standard drill chucks and collet holders common in both benchtop and floor-standing drill presses.

This countersink is suited for use in machine shops, maintenance and repair operations, and light manufacturing settings where consistent recess geometry is required. The single-flute design reduces chatter on softer materials and provides clean entry on sheet metal. It is appropriate for use in handheld drill applications as well as fixed drill press setups where the 1/2-inch shank can be secured properly.

Key Features

• 82-degree included angle matches standard flat-head fastener seating geometry
• Single-flute design minimizes chatter and produces a clean conical recess
• High speed steel construction provides heat and wear resistance during repeated use
• 3/4-inch head diameter accommodates common flat-head screw sizes in metal and wood
• 1/2-inch shank diameter fits standard drill chucks and collet holders

Compatibility

Designed as a general-purpose countersink for use with standard 1/2-inch drill chucks and collet systems in drill presses and handheld drills where an 82-degree flat-head recess is required.

Installation Notes

Install the 1/2-inch shank securely in a drill chuck or collet before use. Power down and de-energize the drill press or disconnect the handheld drill before changing tooling. Use appropriate cutting fluid on ferrous metals to extend tool life and improve finish quality. Eye protection and secure workpiece fixturing are required during operation.
