Value Collection 28627 Countersink 3/8 in 82 Deg 6 Flute Hss

Product Description

The VALUE COLLECTION 28627 is a 6-flute countersink designed for creating conical recesses in metal, wood, and composite materials prior to fastener seating. Built from high speed steel (HSS), this tool delivers consistent cutting performance across a range of workpiece materials. The 3/8 inch head diameter and 82-degree included angle make it suited for standard flat-head fastener applications where a flush or recessed finish is required. It accepts a 1/4 inch shank, making it compatible with common drill chucks and quick-change adapters. Machinists, fabricators, and maintenance technicians reach for this style of countersink for everyday deburring and countersinking tasks on the shop floor or in the field.

This countersink is appropriate for use in light industrial, manufacturing, and general maintenance environments. The 82-degree included angle corresponds to the standard angle used for imperial flat-head machine screws and sheet metal screws, making it a practical fit for ferrous and non-ferrous metal stock, plastics, and similar materials. Its compact size and 1/4 inch shank allow use in standard drill presses, hand drills, and CNC setups where a small-diameter countersink is specified.

Installation Notes

Install the 1/4 inch shank securely in the chuck or collet before operation and verify the tool is fully seated before applying power. Use appropriate cutting speed for the workpiece material and apply cutting fluid when working with harder metals to extend tool life. Wear eye protection and secure the workpiece before beginning any countersinking operation. Inspect the cutting edges for wear or chipping before each use.
