Value Collection SC5090D2 Countersink 90 Degree Hss

Product Description

The VALUE COLLECTION SC5090D2 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 90-degree included angle and a 45-degree centerline angle. The tool accepts a 1/4-inch straight shank and cuts a range from 3/16 inch minimum to 17/32 inch maximum diameter. With zero flutes and right-hand cutting direction, it delivers a clean, consistent chamfer without the chatter sometimes associated with multi-flute designs. Machinists and tool-and-die professionals are the primary users of this style of countersink.

This countersink suits general machining and fabrication environments where standard 90-degree chamfers are required for fastener seating, edge deburring, or hole preparation. It is a single-end tool with no pilot included, making it compatible with standard drill presses, milling machines, and hand-held power tools equipped with a 1/4-inch collet or chuck. Its compact cutting range makes it well suited to light- to medium-duty applications in production and maintenance shop settings.

Key Features

• 90-degree included angle for standard fastener chamfering and countersinking
• High-speed steel construction for durability across common workpiece materials
• Zero-flute design reduces chatter and produces a smooth chamfer surface
• Right-hand cutting direction compatible with conventional drill and mill setups
• 1/4-inch straight-cylindrical shank fits standard collets and drill chucks
• Bright uncoated finish suitable for general-purpose countersinking applications

Compatibility

Designed as an OEM-style replacement or standard tooling option for machines and setups accepting a 1/4-inch straight-cylindrical shank countersink with a 90-degree included angle.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling professional. Secure the 1/4-inch shank firmly in the collet or drill chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Power down the machine and confirm zero rotation before changing or inspecting the tool. Do not exceed the recommended spindle speed for the workpiece material and tool diameter.
