Value Collection BC11P0006 Combo Drill Countersink Size 6

Product Description

The VALUE COLLECTION BC11P0006 is a combination drill and countersink designed for precision hole preparation in metalworking applications. Built from cobalt tool steel with a bright, uncoated finish, this tool bores a pilot hole and forms a 90-degree countersink in a single operation. The 1/2-inch body diameter houses a 7/32-inch drill point, and the tool measures 3 inches in overall length. Right-hand cutting direction suits standard drill press and handheld drilling equipment. Cobalt construction provides heat resistance and edge retention when cutting harder alloys and stainless steel.

This combo drill countersink is suited for fabrication shops, aerospace maintenance, and general metalworking where countersunk fasteners require flush or below-surface seating. The size 6 trade designation corresponds to common machine screw sizing. The plain cutting edge style and non-tapered body make it straightforward to use in standard drill chucks without special toolholding. It is typically installed in drill presses, milling machines, or hand drills running at appropriate spindle speeds for the workpiece material.

Key Features

• Cobalt tool steel construction for improved heat resistance and edge retention in hard materials
• 90-degree included angle forms a standard countersink in a single pass
• 7/32-inch drill point diameter and 7/32-inch drill point length for precise pilot hole sizing
• 1/2-inch body diameter fits standard drill chucks
• Right-hand cut compatible with conventional drilling equipment
• Double end type extends usable tool life

Compatibility

Designed as a size 6 combo drill countersink for use with standard drill chucks accepting a 1/2-inch body diameter tool. Suitable for countersinking applications requiring a 90-degree seat angle in ferrous and non-ferrous metals.

Installation Notes

This tool is installed and operated by machinists, fabricators, or maintenance technicians using drill presses, lathes, or handheld drilling equipment. Secure the tool firmly in the chuck and verify runout before starting the cut. Use cutting fluid appropriate to the workpiece material to extend tool life and improve finish quality. Never exceed the recommended spindle speed for the tool diameter and material being cut.
