M.a. Ford 40218750 Combo Drill Countersink Size 5 Solid Carbide

Product Description

The M.A. FORD 40218750 is a solid carbide combo drill countersink designed to drill and countersink in a single pass. Built to Series 402 standards, it features a 7/16 inch body diameter, a 3/16 inch drill point diameter, and a 60-degree included angle. The bright polished finish reduces friction and helps with chip evacuation. At 2-3/4 inches overall length, this is a long-length tool suited for production and maintenance machining environments. Licensed machinists and tool-room technicians are the primary users of this type of cutting tool.

This combo drill countersink is rated for use on demanding workpiece materials including steel, stainless steel, hardened steel, cast iron, and special alloys. The double-end configuration extends tool life, and the plain cutting edge style suits through-hole and countersink prep on flat and contoured surfaces. It is commonly used in aerospace, industrial fabrication, and precision machining shops where combined drilling and countersinking operations reduce cycle time and tool changes.
