M.a. Ford. 40210930 Combo Drill Countersink 1/4 in Carbide

Product Description

The M.A. FORD. 40210930 is a solid carbide combo drill countersink designed for simultaneous drilling and countersinking in a single pass. Sized as a Number 3, it features a 1/4-inch body diameter, a 7/64-inch drill point diameter, and a 60-degree included angle. The bright polished finish reduces friction and chip buildup during cutting. At 2 inches overall length, this is a long-length tool built for precision work in demanding materials. Right-hand cutting direction and a plain cutting edge style keep the operation straightforward for machinists and tool-and-die professionals.

This combo drill countersink is suited for production and maintenance applications requiring clean countersunk holes in ferrous and high-strength materials. Primary workpiece materials include steel, stainless steel, hardened steel, cast iron, and special alloys. It belongs to M.A. FORD. Series 402 and is configured with a double end type, making it a versatile option for shop environments where tool changes slow down cycle times.

Installation Notes

Installation is performed by machinists or tool and die professionals using standard CNC or manual drill press setups. Secure the tool firmly in a compatible collet or chuck rated for the 1/4-inch body diameter before operation. Ensure the workpiece is properly fixtured and the spindle speed is set appropriately for the workpiece material and tool diameter before engaging the cut. Inspect the cutting edges for wear or chipping before each use, particularly when working with hardened steel or special alloys.
