Value Collection SC1082024 Countersink 82 Degree Hss

Product Description

The VALUE COLLECTION SC1082024 is a single-flute, high-speed steel countersink designed for creating clean, chamfered seat profiles in metal and similar materials. Built with an 82-degree included angle and a straight cylindrical shank measuring 0.25 inches in diameter, this tool mounts directly into standard drill chucks and countersinking holders without additional adapters. The 0.375-inch head diameter delivers controlled material removal in a right-hand cutting direction. At 0.18 pounds, the tool is compact and well-suited for bench drilling, CNC drill press work, and handheld electric drill applications. Machinists, maintenance technicians, and trade professionals reaching for a reliable, uncoated HSS countersink for everyday deburring and fastener-seat preparation will find this a straightforward choice.

This countersink is intended for general countersinking operations where an 82-degree fastener seat angle is required — the standard angle for flat-head screws commonly used in metalworking, fabrication, and light industrial assembly. The bright, uncoated finish means there is no coating delamination risk when used on softer ferrous and non-ferrous metals. It is a single-end tool with no pilot included, making it best suited for use in a drill press or guided fixture where center alignment is controlled by the operator or workholding setup.

Key Features

• 82-degree included angle matches the standard flat-head screw seat geometry for metalworking applications
• Single flute geometry reduces cutting resistance and simplifies resharpening
• High-speed steel construction provides adequate hardness and toughness for ferrous and non-ferrous materials
• Bright, uncoated finish — no coating to chip or delaminate during use
• Straight cylindrical shank at 0.25 inches fits standard drill chucks and countersink holders
• No pilot included — designed for use with controlled drill press or guided setups

Compatibility

Designed as an OEM-style replacement or direct-use countersink compatible with standard drill chucks and countersinking holders accepting a 0.25-inch straight cylindrical shank.

Installation Notes

Installation is performed by machinists, fabricators, and maintenance technicians using a drill press, mill, or handheld electric drill. Secure the straight shank firmly in the chuck before operation and verify the workpiece is clamped to prevent rotation. Always wear eye protection when operating rotary cutting tools. Do not exceed the recommended RPM range for the material being countersunk — consult standard HSS cutting speed charts for the specific workpiece material.
