Value Collection SC4060024 Countersink 60 Deg 3 Flute Hss

Product Description

The VALUE COLLECTION SC4060024 is a single-end, straight-shank countersink designed for creating clean, accurately angled seat holes in metal and other materials. Built from high-speed steel with a bright uncoated finish, it features a 60-degree included angle and three flutes for efficient chip evacuation during right-hand cutting operations. The 1/4-inch straight-cylindrical shank fits standard drill chucks and quick-change holders. With a 3/8-inch head diameter, this countersink is sized for common fastener seating applications in light-to-medium machining work. No pilot is included, so the operator controls centering through technique or a pre-drilled guide hole.

This countersink is suited for machinists, tool and die techs, and maintenance professionals working on deburring, fastener seating, and edge-chamfering tasks. The 60-degree included angle matches common flat-head screw geometries used in general metalworking and fabrication. Its compact head size and standard 1/4-inch shank make it compatible with bench drill presses, hand drills, and CNC spindles running right-hand rotation. Typical applications include sheet metal, aluminum, mild steel, and similar workpieces where a clean countersunk seat is required before fastener installation.

Key Features

• 60-degree included angle suits flat-head fastener seating in metalworking applications
• Three-flute design promotes chip clearance and a smoother finished seat
• High-speed steel construction provides durability across common metals and alloys
• 1/4-inch straight-cylindrical shank fits standard drill chucks and quick-change systems
• Bright uncoated finish allows visual wear inspection during service life
• Single-end, no-pilot design offers flexibility across pre-drilled hole sizes

Compatibility

Designed as a general-purpose countersink for use in drill presses, hand drills, and CNC spindles requiring a 1/4-inch straight shank and right-hand cutting rotation.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard drill press or hand-drill setups. Secure the workpiece before operation to prevent movement during countersinking. Run at appropriate spindle speeds for the workpiece material — lower speeds are generally recommended for harder metals. Inspect the cutting edges before each use and replace when wear causes chatter or an uneven seat profile.
