Value Collection SC5082D0 Countersink 82 Deg Hss

Product Description

The VALUE COLLECTION SC5082D0 is a single-flute countersink machined from high-speed steel for countersinking and deburring operations in metal, wood, and composite materials. Configured with an 82-degree included angle and a 41-degree centerline angle, it produces standard flat-head fastener recesses used across general fabrication, maintenance, and production environments. The cutting geometry runs right-hand and the shank is straight-cylindrical at 0.25 inches in diameter, making it compatible with standard drill chucks and quick-change holders. The bright, uncoated finish suits general-purpose applications where coating is not required.

This countersink is suited for machinists, tool-and-die technicians, maintenance mechanics, and fabricators working in shops, production floors, or field maintenance settings. The 82-degree angle matches the head geometry of most imperial flat-head machine screws, making it a practical choice for hole prep on sheet metal, aluminum, and mild steel. The double-end configuration and compact cutting range of 0.0625 inches minimum to 0.234 inches maximum diameter fit a wide range of fastener sizes in light to medium-duty work.

Key Features

• 82-degree included angle matches standard imperial flat-head fastener geometry
• High-speed steel construction provides durability in general-purpose cutting applications
• Straight-cylindrical shank at 0.25 inches fits standard drill chucks and quick-change holders
• Double-end design extends usable tool life
• Bright, uncoated finish for general-purpose use across a range of workpiece materials
• Suited for both countersinking and deburring operations

Compatibility

Designed as a general-purpose countersink for use with standard drill presses, hand drills, and CNC machining centers accepting a 0.25-inch straight-cylindrical shank. Cutting range of 0.0625 inches to 0.234 inches suits common imperial flat-head fastener sizes.

Installation Notes

Install in a drill chuck or quick-change holder rated for the shank diameter before starting the machine. Secure the workpiece firmly to prevent movement during the countersinking operation. Run at appropriate speed for the workpiece material and tool diameter, reducing speed for harder materials to avoid premature wear. Inspect the cutting end for damage before each use.
