Value Collection BC10P0003 Combo Drill Countersink No. 3

Product Description

The VALUE COLLECTION BC10P0003 is a combination drill and countersink designed for accurate hole preparation and countersinking in a single operation. Machined from cobalt tool steel with a bright, uncoated finish, this No. 3 trade size tool features a 1/4 inch body diameter and a 7/64 inch drill point. The 82-degree included angle produces a standard countersink profile suited for flat-head fasteners. With a compact 2 inch overall length and right-hand cutting direction, it is a practical bench tool for machinists, pipefitters, and fabricators working in metal, stainless, and harder alloys where cobalt tooling is preferred.

This combo drill countersink is used in metalworking, fabrication shops, and maintenance environments where countersunk holes for flat-head machine screws or rivets are required. The plain cutting edge style and double end type provide flexibility in tool use and extend service life. It is well-suited for hand-held drilling operations or use in a drill press or milling setup where controlled countersink depth is needed.

Installation Notes

Use appropriate cutting fluid for harder alloys to reduce heat buildup and extend tool life. Inspect the cutting edges before each use and replace the tool if chipping or wear is evident.
