Value Collection SC50100D3 Countersink 100 Degree Hss

Product Description

The VALUE COLLECTION SC50100D3 is a single-end, straight-cylindrical-shank countersink designed for countersinking and deburring operations in metal fabrication and general machining work. Built from high-speed steel with a bright uncoated finish, this tool features a 100-degree included angle and a right-hand cutting direction. The shank diameter measures 0.5 inches, the minimum cutting diameter is 0.3125 inches (5/16 inches), and the maximum cutting diameter reaches 0.78125 inches (25/32 inches). It is installed and used by machinists, tool-and-die workers, and maintenance technicians working with drill presses, lathes, or hand-held power tools.

This countersink is suited for light to medium-duty countersinking and deburring tasks on ferrous and non-ferrous workpieces. The 100-degree included angle accommodates fastener head geometries common in aerospace and general industrial applications. The bright uncoated finish makes it appropriate for use on a wide range of materials where coating retention is not a critical factor. It ships as a single tool with no pilot included and no additional accessories.

Key Features

• 100-degree included angle for countersinking standard and aerospace-style fastener seats
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Right-hand cutting direction compatible with standard drill press and lathe setups
• Straight-cylindrical 0.5-inch shank fits common chuck sizes
• Bright uncoated finish suitable for general-purpose shop use
• Single-end design with no pilot for flexible, operator-guided positioning

Compatibility

Designed as a general-purpose countersink for use in drill presses, lathes, and hand-held power tools accepting a 0.5-inch straight-cylindrical shank.

Installation Notes

Install the shank securely in a compatible chuck before operation and verify the workpiece is clamped or fixtured to prevent movement. Power down the machine fully before inserting or removing the tool. Because no pilot is included, feed rate and alignment must be controlled by the operator to maintain accurate seat geometry. Wear appropriate eye protection and follow shop safety protocols when deburring or countersinking.
