Value Collection BC10P0005 Combo Drill Countersink Cobalt

Product Description

The VALUE COLLECTION BC10P0005 is a combination drill and countersink tool designed for metalworking and fabrication applications. Built from cobalt tool steel with a bright, uncoated finish, it handles harder workpiece materials where standard high-speed steel tends to wear prematurely. The tool features a 3/16 inch drill point diameter, a 3/16 inch drill point length, and an 82-degree included angle — the standard angle for flat-head fastener seating in metal. At 2-3/4 inches overall length, it fits standard drill press chucks and hand drill setups. Machinists, fabricators, and tool-and-die tradespeople are the primary users.

This tool is sized as a trade size 5 countersink with a 7/16 inch body diameter. It is well suited for countersinking pilot holes in steel, stainless steel, aluminum, and other metals ahead of flat-head screw or rivet installation. The right-hand cutting direction is compatible with standard clockwise drill rotation. The plain cutting edge style and non-tapered body make it straightforward to resharpen. It is not classified as an aircraft-style or long-length tool, placing it in standard general-purpose countersinking use.

Key Features

• Cobalt tool steel construction for improved heat and wear resistance in hard materials
• 82-degree included angle matches the standard flat-head fastener countersink profile
• 3/16 inch drill point diameter and 3/16 inch drill point length for combined drilling and countersinking in one pass
• 7/16 inch body diameter, trade size 5
• Right-hand cut compatible with standard clockwise drill rotation
• Bright uncoated finish for easy visual inspection of cutting edge condition

Compatibility

Designed as a general-purpose combo drill countersink for use in standard drill presses, CNC drilling setups, and hand drills with a chuck capable of accepting a 7/16 inch body diameter shank.

Installation Notes

This tool is installed and operated by machinists, fabricators, or maintenance tradespeople using a drill press or hand drill. Always secure the workpiece before drilling to prevent rotation. Set drill speed appropriate for the workpiece material and tool diameter — cobalt tooling tolerates higher surface speeds than standard HSS but still requires proper cutting fluid on ferrous materials to extend tool life. Inspect the cutting edges before each use and remove the tool from service if chipping or excessive wear is observed.
