Value Collection SC2060056 Countersink 60 Deg 6 Flute Hss

Product Description

The VALUE COLLECTION SC2060056 is a single-end, 6-flute countersink designed for right-hand cutting in metal fabrication and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers clean, accurate countersunk holes at a 60-degree included angle (30-degree centerline angle). The straight-cylindrical shank measures 0.5 inches in diameter with a shank length of 1.3125 inches, and the head diameter reaches 0.875 inches. This tool seats directly into a standard drill press, milling machine, or hand drill chuck without requiring a pilot. Machinists, tool-and-die workers, and general fabricators install this type of countersink for deburring, chamfering, and preparing fastener seats.

This countersink is suited for countersinking operations on ferrous and non-ferrous metals in both job-shop and production environments. The 6-flute geometry distributes cutting load across multiple edges, which reduces chatter and produces a smoother finish compared to single- or 3-flute designs. It is appropriate for use in CNC machining centers, drill presses, and manual milling setups where a 60-degree countersink profile is required. No pilot is included, so the operator controls centering by fixture or layout.

Key Features

• 60-degree included angle (30-degree centerline) for standard 60-degree countersink profiles
• 6-flute cutting geometry reduces chatter and improves surface finish
• High-speed steel construction provides toughness and heat resistance during metal cutting
• Bright, uncoated finish suitable for general-purpose machining without coating compatibility concerns
• Straight-cylindrical 0.5-inch shank fits standard chucks and collets
• Single-end design with no pilot — compatible with fixturing or center-punched layouts

Compatibility

Designed as an OEM-style replacement or standard tooling addition for drill presses, milling machines, and CNC machining centers accepting a straight-cylindrical 0.5-inch shank tool in countersinking applications.

Installation Notes

Installation is performed by machinists or qualified tooling technicians. Power down and lock out the machine before inserting or removing the tool from the chuck or collet. Secure the shank fully to the recommended engagement depth per the machine manufacturer's guidelines before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality.
