Value Collection BC04P0002 Combo Drill Countersink Cobalt

Product Description

The VALUE COLLECTION BC04P0002 is a cobalt combo drill countersink designed for drilling and countersinking in a single pass. With a 3/16-inch body diameter and a 5/64-inch drill point diameter, this tool produces a clean, accurately sized pilot hole and countersink simultaneously. The 118-degree drill point angle is standard for general metalworking applications, and the 60-degree included angle on the countersink suits common flat-head fastener seating. The bright, uncoated cobalt construction provides heat resistance during cutting, making it well suited for harder ferrous and stainless materials. At 1-7/8 inches overall length, this is a compact tool appropriate for close-tolerance work. Installation and fabrication tradespeople will recognize this as a reliable single-tool solution for countersunk fastener prep.

This combo drill countersink is intended for use in metalworking, fabrication, and mechanical assembly applications where countersunk holes are required for flat-head screws or rivets. It is sized as a trade size 2 tool and is applicable wherever a 3/16-inch body combo countersink is specified. Right-hand cut geometry makes it compatible with standard drill presses, CNC machines, and handheld power drills with conventional chuck rotation. The double end type extends tool life by providing two usable cutting ends. This tool suits shops and field technicians working in HVAC equipment fabrication, plumbing fixture assembly, or general mechanical trades requiring precise countersink preparation in metal substrates.

Installation Notes

This tool should be installed by a machinist or qualified tradesperson familiar with metal cutting operations. Ensure the drill or machine spindle is fully stopped before inserting or removing the tool from the chuck. Use appropriate cutting fluid or lubricant when drilling harder alloys to preserve the cutting edge. Follow applicable shop safety standards and wear rated eye protection during all drilling and countersinking operations.
