Value Collection BC04P0008 Combo Drill Countersink Size 8

Product Description

The VALUE COLLECTION BC04P0008 is a cobalt combo drill countersink designed for drilling and countersinking in a single pass. Built to trade size 8 with a 3/4-inch body diameter, this tool features a 5/16-inch point diameter and a 118-degree drill point angle. The 60-degree included angle delivers clean, consistent countersink geometry suited for fastener seating in metal fabrication, HVAC panel work, and mechanical assembly. Right-hand cut with a plain cutting edge and double end type, it offers extended service life in tough materials where high-speed steel would wear prematurely.

This combo drill countersink is used in light industrial and trade shop applications where ferrous and non-ferrous metals require precise countersink prep before fastener installation. Common install scenarios include ductwork fabrication, equipment panel assembly, and structural metalwork. The cobalt construction makes it appropriate for stainless steel, hardened steel, and high-temperature alloys that would degrade standard HSS tooling. It is installed in standard drill presses, CNC mills, and handheld drills with compatible chuck sizes.

Key Features

• Cobalt tool material for superior heat resistance and wear life in hard metals
• 118-degree drill point angle for efficient penetration in ferrous materials
• 60-degree included angle for consistent fastener countersink geometry
• Right-hand cut, plain cutting edge for clean entry and exit
• Double end type extends usable tool life
• Bright uncoated finish for straightforward inspection and regrinding

Compatibility

Designed as an OEM-style replacement or direct-use combo drill countersink for trade size 8 applications in standard drill chucks accepting 3/4-inch body diameter tooling.

Installation Notes

This tool is installed by machinists, fabricators, and trade technicians using a drill press, milling machine, or handheld drill. Secure the workpiece fully before operation and confirm the chuck is rated for the body diameter. Power down and lock out all equipment before changing tooling. Do not exceed the recommended RPM range for cobalt tooling in the material being drilled.
