Value Collection SC2160056 Countersink 7/8 in 60 Deg 6 Flute

Product Description

The VALUE COLLECTION SC2160056 is a single-end cobalt steel countersink designed for creating clean, accurately angled seat recesses in metal and hard materials. It features a 7/8 inch head diameter and a 60-degree included angle, which corresponds to a 30-degree centerline angle. Six flutes provide smooth cutting action and efficient chip evacuation. The straight cylindrical shank measures 1/2 inch in diameter, making it compatible with standard drill chucks and countersink holders. The bright, uncoated finish is standard for cobalt tooling used in general-purpose countersinking applications. This tool is suited for machinists, fabricators, and maintenance technicians working with steel, stainless, and other ferrous materials.

This countersink is intended for countersinking operations in metal fabrication, machine shops, and maintenance environments. It is used to prepare fastener seats for flat-head screws and bolts requiring a 60-degree included angle. The 6-flute geometry makes it appropriate for use in drill presses, milling machines, and hand-held electric drills where a controlled, chatter-reduced cut is needed. It does not include a pilot and is sold as a single-end tool without an integrated pilot guide, so proper centering technique or a drill press setup is recommended for best results.

Key Features

• 7/8 inch head diameter with a 60-degree included angle for standard flat-head fastener seat preparation
• 6-flute design reduces chatter and produces a smoother finish compared to fewer-flute countersinks
• Cobalt steel construction provides increased heat and wear resistance for use in harder ferrous materials
• 1/2 inch straight cylindrical shank fits standard drill chucks and countersink holders
• Bright, uncoated finish — no additional coating to affect dimensional tolerances
• Single-end tool with no integrated pilot; suited for setups where centering is controlled externally

Compatibility

Designed as an OEM-style countersink for use in standard 1/2 inch capacity drill chucks and countersink holders on drill presses, milling machines, and hand drills requiring a 60-degree, 6-flute cobalt countersink.

Installation Notes

Installation and use should be performed by qualified machinists or trades personnel familiar with rotary cutting tools. Secure the shank firmly in the chuck and verify runout before cutting. Always wear appropriate eye protection and follow shop safety protocols when operating drill presses or milling equipment. Do not exceed the recommended RPM for cobalt tooling in the material being worked.
