Value Collection SC2082132 Countersink 82 Deg 6 Flute Hss

Product Description

The VALUE COLLECTION SC2082132 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 an 82-degree included angle — the standard angle for flat-head fastener seating in most aerospace and general machining work. The straight-cylindrical shank measures 0.75 inches in diameter and 1.625 inches in length, making it compatible with standard drill chucks and milling machine holders. No pilot is included. This tool is suited for machinists, tool-and-die professionals, and maintenance technicians working with ferrous and non-ferrous materials.

This countersink is used in general metalworking, fabrication shops, and maintenance environments where flat-head screw or bolt seating is required. The 1.5-inch head diameter accommodates a wide range of fastener sizes. The 82-degree angle is consistent with standard flat-head machine screw geometry, making this tool appropriate for production countersinking on milled or drilled workpieces. It is typically applied in manual drill press, CNC, or hand-held power tool setups where a straight-cylindrical shank is specified.

Key Features

• 82-degree included angle (41-degree centerline angle) matches standard flat-head fastener geometry
• 6-flute design reduces chatter and produces a smoother countersunk finish compared to fewer-flute designs
• High-speed steel construction provides durability across ferrous and non-ferrous materials
• Bright/uncoated finish — no coating buildup to affect dimensional accuracy
• Straight-cylindrical shank at 0.75 inches diameter fits standard drill chucks and collets
• Single-end tool with no pilot — allows use with or without a separate guide bushing

Compatibility

Designed as a direct-fit countersink for drill presses, CNC machining centers, and hand-held power tools equipped with a standard straight-cylindrical chuck or collet accepting a 0.75-inch shank.

Installation Notes

Installation and use should be performed by a qualified machinist or trained technician familiar with cutting tool setup and speeds. Secure the shank firmly in the chuck or collet before operation and verify runout before engaging the workpiece. Always power down and lock out the spindle before changing or adjusting tooling. Use appropriate cutting fluid or lubrication for the workpiece material to extend tool life and improve finish quality.
