Value Collection 217-9212 Cobalt Drill Countersink Set 5 Pc

Product Description

The VALUE COLLECTION 217-9212 is a 5-piece cobalt combo drill and countersink set designed for right-hand countersinking operations across a range of trade sizes 1 through 5. Built from cobalt steel with a bright, uncoated finish, each tool features a 60-degree included angle and a plain cutting edge for clean, consistent countersink geometry. The double-ended design extends tool life by providing two usable cutting ends per piece. This set is suited for machinists, tool-and-die technicians, metalworkers, and maintenance professionals who countersink metal workpieces as part of routine fabrication or repair workflows.

This set covers countersinking applications across five standard trade sizes, making it a practical addition to a shop or field kit where multiple countersink sizes are needed without carrying individual tools. The included plastic storage case keeps all five pieces organized and protected between uses. The cobalt steel construction handles harder base materials that would wear down standard high-speed steel tools more quickly.

Installation Notes

Combo drill countersinks are installed by machinists and metalworkers using a drill press, milling machine, or handheld power drill with a compatible chuck. Secure the workpiece firmly before operation to prevent movement during cutting. Inspect both cutting ends for wear or chipping before use, and replace the tool if either end is damaged. Follow applicable shop safety standards for eye protection and workpiece clamping when operating rotary cutting tools.
