Value Collection SC50100D2 Countersink 100 Deg Hss

Product Description

The VALUE COLLECTION SC50100D2 is a single-end, straight-cylindrical-shank countersink designed for countersinking and deburring operations in metal and similar materials. Built from high-speed steel with a bright uncoated finish, it features a 100-degree included angle and right-hand cutting direction. The 1/4-inch straight shank accepts standard drill press and hand-drill chucks. With no flutes, this design functions as a zero-flute countersink, delivering smooth, chatter-resistant cuts well suited for production environments and repetitive deburring tasks. Machinists and tool-and-die technicians are the primary users of this tool.

This countersink handles a minimum cutting diameter of 3/16 inches and a maximum cutting diameter of 17/32 inches, making it appropriate for a wide range of fastener seat preparations. It is used in machine shops, fabrication facilities, and maintenance environments wherever screw-head seats, edge chamfers, or burr removal are required on ferrous and non-ferrous workpieces. The zero-flute geometry makes it particularly effective on softer materials where multi-flute tools can chatter or grab.

Key Features

• 100-degree included angle suits a broad range of flat-head fastener seat preparations
• Zero-flute design produces smooth, chatter-free cuts on soft and medium-hardness materials
• High-speed steel construction provides durability across general-purpose machining applications
• Bright uncoated finish for easy visual inspection and compatibility with standard cutting fluids
• 1/4-inch straight cylindrical shank fits most standard chuck sizes
• Single-end tool with no pilot, allowing free placement over existing hole centers

Compatibility

Designed as a general-purpose countersink for use in standard drill presses, hand drills, and milling machine chucks accepting a 1/4-inch straight cylindrical shank.

Installation Notes

A licensed machinist or experienced fabricator should secure the workpiece firmly before operation to prevent movement during cutting. Always power down and disconnect the machine before changing or inspecting the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve cut quality. Follow applicable shop safety standards and machine-guarding requirements when operating rotary cutting tools.
