Value Collection SC3060032 Countersink 60 Deg 4 Flute Hss

Product Description

The VALUE COLLECTION SC3060032 is a 4-flute high-speed steel countersink designed for right-hand cutting in metal and general-purpose machining applications. It features a 60-degree included angle, which is standard for machine screw and flat-head fastener seating in steel, aluminum, and similar materials. The straight cylindrical shank measures 1/2 inch in diameter with a shank length of 2-1/4 inches, making it compatible with standard drill chucks and collet holders. The bright uncoated finish keeps cost low for general-duty use where coating is not required. Machinists and maintenance technicians reach for this tool when countersinking holes to accept flat-head fasteners or deburring drilled holes in production and job-shop environments.

This countersink is suited for use in drill presses, milling machines, and hand-held drill motors with appropriate speed control. The 60-degree angle is the most common countersink geometry for metric and unified inch flat-head machine screws. It is a single-end tool without a pilot, so the operator centers it over a pre-drilled hole. Typical applications include sheet metal work, fixture fabrication, and general metalworking where consistent countersink geometry is required for flush fastener seating.

Key Features

• 60-degree included angle for standard flat-head fastener seating
• 4-flute design for smooth cutting action and reduced chatter
• High-speed steel construction for durability across a range of metals
• 1/2 inch straight cylindrical shank fits standard drill chucks and collet holders
• Bright uncoated finish suitable for general-duty countersinking
• Single-end, no-pilot design for use over pre-drilled holes

Compatibility

Designed as a general-purpose countersink for use in drill presses, milling machines, and hand drills equipped with a 1/2 inch or larger chuck capable of accepting a straight cylindrical shank.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with rotary cutting tools. Secure the shank firmly in the drill chuck or collet before operation and verify runout is within acceptable limits. Set spindle speed appropriate for the workpiece material and tool diameter before engaging the cut. Always wear appropriate eye protection and ensure the workpiece is clamped securely before countersinking.
