Value Collection BC11P0007 Combo Drill Countersink Size 7

Product Description

The VALUE COLLECTION BC11P0007 is a combination drill and countersink designed for precision countersinking operations in metalworking and fabrication applications. Built from cobalt tool steel with a bright, uncoated finish, this tool handles hard materials where standard high-speed steel bits fall short. The body diameter measures 5/8 inches, with a 1/4-inch drill point diameter, a 1/4-inch drill point length, and an overall length of 3-1/4 inches. The 90-degree included angle and plain cutting edge style produce clean, accurate countersink seats. A licensed machinist or toolroom technician typically selects this tool for production and repair drilling setups.

This combo drill countersink is suited for right-hand cutting on ferrous and non-ferrous metals in both shop and field fabrication environments. The double-end design extends tool life by providing two usable cutting ends before replacement is needed. Trade size 7 makes it a common choice for countersinking screw clearance holes in structural and sheet metal work where a consistent 90-degree seat is required. It is sold individually with a minimum order quantity of one unit.

Installation Notes

Installation is performed by machinists or metal fabricators in a controlled shop or field environment. Secure the tool firmly in the appropriate collet or chuck before operation, and ensure the workpiece is clamped to prevent movement. Always operate at the feed rate and spindle speed recommended for cobalt tooling in the specific workpiece material. Wear appropriate eye protection and follow applicable shop safety standards when running any rotary cutting tool.
