Value Collection SC2060040 Countersink 60 Degree 6 Flute

Product Description

The VALUE COLLECTION SC2060040 is a single-end, 6-flute countersink designed for precise countersinking operations in metalworking and fabrication applications. Built from high-speed steel with a bright, uncoated finish, this tool delivers consistent performance when creating clean, tapered seat profiles. The 60-degree included angle and straight-cylindrical shank make it a standard choice for aerospace, machine shop, and general manufacturing work. Machinists and tool-and-die professionals reach for this style of countersink when preparing bolt and screw clearance holes for flush-seat fasteners. The tool weighs 0.06 pounds and is compatible with standard drill press and CNC spindle setups.

This countersink is suited for right-hand cutting in materials where a 60-degree seat angle is required. The 5/8-inch head diameter and 1/2-inch straight-cylindrical shank fit a wide range of standard chucks and collet holders found in machine shops, maintenance facilities, and production environments. With 6 flutes, the tool distributes cutting load evenly, which reduces chatter and produces a smoother finished seat surface compared to lower-flute-count alternatives. It does not include a pilot and is sold as a single-end tool, making it straightforward to index and replace when worn.

Key Features

• 60-degree included angle (30-degree centerline angle) for standard flush-fastener seat preparation
• 6-flute geometry reduces chatter and improves surface finish in the countersunk seat
• High-speed steel construction provides durability across common ferrous and non-ferrous materials
• Straight-cylindrical shank at 1/2 inch fits standard drill press chucks and milling machine collets
• Bright, uncoated finish for general-purpose use without specialized surface treatment
• Single-end design with no pilot for straightforward setup and replacement

Compatibility

Designed as a general-purpose countersink for use in standard drill press, lathe, and milling machine setups requiring a 1/2-inch straight-cylindrical shank and a 60-degree seat angle.

Installation Notes

Installation and use of this countersink should be performed by a qualified machinist familiar with proper speeds and feeds for high-speed steel tooling. Secure the 1/2-inch shank firmly in the chuck or collet before operation, and verify the workpiece is clamped or fixtured to prevent movement. Power down and de-energize the spindle completely before changing or inspecting the tool. Do not exceed the recommended surface footage for the workpiece material to avoid premature tool wear or tool failure.
