Value Collection 156400008000006 Drill Countersink Sz8

Product Description

The VALUE COLLECTION 156400008000006 is a combination drill and countersink designed for creating cleanly bored, countersunk holes in a single pass. Built from high-speed steel with a bright, uncoated finish, this tool features a 3/4 inch body diameter and a 5/16 inch drill point diameter. It has a 6 inch overall length, making it a long-length tool suited for deeper reach applications. The right-hand cut and plain cutting edge style are standard for general-purpose metalworking operations. Machinists and tool-and-die technicians are the primary installers of this tool in lathe, mill, or drill press setups.

This combo drill countersink is used in metalworking and fabrication shops where countersinking for size 8 fasteners is required. The double end type allows for extended tool life by providing two usable cutting ends. At a 60-degree included angle, it is suited for standard countersunk screw seat preparation in steel, aluminum, and similar materials. It is not configured for aircraft-style applications and is not a tapered design, keeping it straightforward for everyday shop use.
