M.a. Ford. 40502500 Combo Drill Countersink 1/8 in Carbide

Product Description

The M.A. FORD. 40502500 is a Size 00 combination drill countersink with a 1/8-inch body diameter, manufactured from solid carbide with a bright polished finish. This double-end tool performs simultaneous drilling and countersinking in a single pass, reducing tool changes and setup time. The 60-degree included angle produces a clean countersink seat suitable for flathead fasteners and center-drilling operations. At 5 inches overall length, it is classified as a long-length tool and is designed for right-hand cutting. Machinists and tooling technicians working in precision machining environments will find this part suited to demanding production and job-shop applications.

The 40502500 is designed for use on cast iron, hardened steel, special alloys, stainless steel, and standard steel workpieces, covering both primary and secondary material categories. The plain cutting edge style and 0.0250-inch drill point diameter make it appropriate for small-diameter center drilling and countersinking tasks. It fits Series 405 tooling setups and carries no taper, making it a straight-shank tool compatible with standard collet and chuck systems used in vertical mills, lathes, and drill presses across light and heavy manufacturing environments.

Key Features

• Solid carbide construction for extended tool life in hardened and abrasive materials
• Double-end design doubles usable tool life before replacement
• 60-degree included angle for standard countersink seat geometry
• 0.0250-inch drill point diameter for precision small-bore entry
• Right-hand cut with plain cutting edge style for clean, controlled material removal
• Long-length classification at 5 inches OAL for deeper reach applications

Compatibility

Designed for use with Series 405 tooling. Compatible workpiece materials include cast iron, hardened steel, special alloy, stainless steel, and steel. Fits standard collet and chuck systems accepting a 1/8-inch shank diameter.

Installation Notes

This tool is installed and operated by machinists and CNC or manual machine operators. Before tool changes, de-energize the machine and confirm the spindle is fully stopped. Secure the shank firmly in a collet or drill chuck rated for the diameter before operation. Do not use this tool in impact or hammer-drill mode; it is designed for rotary cutting only.
