Value Collection BC10P0007 Combo Drill Countersink Size 7

Product Description

The VALUE COLLECTION BC10P0007 is a combination drill and countersink designed for precision metalworking and fabrication applications. Built from cobalt tool steel with a bright, uncoated finish, this bit drills a pilot hole and countersinks in a single pass. It features a 5/8-inch body diameter, a 1/4-inch drill point diameter, and a 1/4-inch drill point length, with an overall length of 3.25 inches. The 82-degree included angle is suited for standard flat-head fastener seating. Right-hand cutting direction and a plain cutting edge style make this a straightforward, reliable tool for machinists and fabricators working with ferrous and stainless materials.

This combo drill countersink is intended for use in metalworking environments where cobalt tooling is specified for harder alloys, stainless steel, or heat-resistant materials. The double-end design extends tool life by providing two usable ends. Trade size 7 identifies the pilot drill size, and the non-tapered body fits standard tool holders and drill chucks. Typical applications include countersinking for flat-head machine screws in steel plate, structural components, and sheet metal assemblies in industrial, maintenance, and fabrication settings.

Key Features

• Cobalt tool steel construction for use in harder and heat-resistant alloys
• 82-degree included angle for standard flat-head fastener countersinking
• Double-end design provides two cutting ends to extend service life
• Right-hand cut with plain cutting edge style for consistent chip clearance
• Bright, uncoated finish — no coating to chip or peel under heavy use
• Non-tapered body seats securely in standard drill chucks and tool holders

Compatibility

Designed as a standard trade-size 7 combination drill countersink for use in drill presses, CNC machines, and hand drills with compatible chuck sizes accepting a 5/8-inch body diameter tool.

Installation Notes

Installation and use should be performed by qualified machinists or fabricators familiar with proper speeds and feeds for cobalt tooling. Secure the workpiece before operation and set spindle speed appropriate for the material being drilled. Inspect both cutting ends before use and replace the tool if chipping or excessive wear is observed. Always use appropriate cutting fluid when drilling stainless steel or hardened alloys to manage heat buildup.
