Value Collection SC2082148 Countersink 82 Deg 6 Flute Hss

Product Description

The VALUE COLLECTION SC2082148 is a single-end, 6-flute countersink designed for right-hand cutting in metal and general fabrication applications. Built from high-speed steel (HSS) with a bright uncoated finish, it features a 1 inch straight-cylindrical shank and a 1-3/4 inch head diameter. The 82-degree included angle (41-degree centerline angle) matches standard flat-head fastener geometry, making it a common choice for machinists, toolmakers, and maintenance professionals working on metal fabrication or assembly operations.

This countersink is suited for use in manual drill presses, CNC machining centers, and turret lathes where a consistent countersink profile is required for 82-degree flat-head fasteners. The straight-cylindrical shank allows direct mounting in standard drill chucks or collet systems without adapters. The bright finish leaves the HSS substrate exposed, which is appropriate for general-purpose steel, aluminum, and softer non-ferrous metals. No pilot is included, so the operator controls concentricity through the spindle setup.

Key Features

• 82-degree included angle matches standard flat-head screw geometry
• 6 flutes provide smooth cutting action and even chip evacuation
• High-speed steel construction handles general-purpose metal countersinking
• 1 inch straight-cylindrical shank fits standard drill chucks and collets
• 1-3/4 inch head diameter for larger-diameter countersink applications
• Bright uncoated finish — no coating to chip or delaminate in interrupted cuts

Compatibility

Designed as a general-purpose countersink compatible with standard drill presses, CNC machining centers, and manual lathes equipped with a 1 inch chuck or collet to accept a straight-cylindrical shank.

Installation Notes

Installation is performed by machining professionals or toolroom personnel. Secure the shank firmly in the chuck or collet before operation and verify runout with a dial indicator if concentricity is critical. Always power down and lock out the spindle before changing tooling. Feed rate and spindle speed should be set per the workpiece material to avoid work-hardening or chatter.
