Value Collection SC1082032 Countersink 82 Deg 1 Flute Hss

Product Description

The VALUE COLLECTION SC1082032 is a single-flute countersink designed for creating conical seat profiles in metal and similar materials. Built from high-speed steel with a bright uncoated finish, this tool features an 82-degree included angle and a 1/2-inch head diameter. It mounts on a 1/4-inch straight cylindrical shank, making it compatible with standard drill chucks and quick-change collet holders. The right-hand cutting direction suits conventional drill press and handheld drill operation. Machinists, fabricators, and maintenance technicians use this countersink to prepare holes for flat-head fasteners and to deburr drilled openings in production and repair work.

This countersink is suited for light-duty countersinking tasks in sheet metal, aluminum, mild steel, and similar workpieces where a clean 82-degree seat is required. The single-flute design reduces chatter on manual drilling equipment and low-speed drill presses. It is a practical option for job-shop environments, maintenance facilities, and field service kits where a compact, general-purpose countersink is needed without a pilot guide. Typical applications include fastener seat preparation and edge chamfering on structural and enclosure components.

Key Features

• 82-degree included angle for standard flat-head fastener seating
• Single-flute geometry minimizes chatter on manual and low-speed equipment
• High-speed steel construction provides durability across metal and light alloy materials
• Bright uncoated finish for general-purpose use without added coating cost
• 1/4-inch straight cylindrical shank fits standard drill chucks and collets
• No pilot included - suitable for use without a guide pin in pre-drilled holes

Compatibility

Designed as a general-purpose countersink for use in standard drill chucks and collet holders accepting a 1/4-inch straight cylindrical shank.

Installation Notes

This tool is installed and operated by machinists, fabricators, or maintenance technicians using a drill press, hand drill, or milling machine. Secure the workpiece firmly before operation and ensure the drill chuck is fully tightened on the shank before running. Start at a low spindle speed and apply light, consistent feed pressure to avoid oversizing the seat. Inspect the countersink edge for wear regularly, as a dull single-flute tool can cause surface tearing on softer materials.
