M.a. Ford 40518750 Combo Drill Countersink Solid Carbide

Product Description

The M.A. FORD 40518750 is a solid carbide combination drill and countersink designed for precision countersinking and drilling in a single operation. Built to Series 405 standards, it features a 7/16-inch body diameter, a 3/16-inch drill point diameter, and a 60-degree included angle that produces clean, consistent countersunk seats. The bright polished finish reduces friction and aids chip evacuation. At 5 inches overall length, this is a long-length tool suited for applications requiring extended reach. Right-hand cut geometry and a plain cutting edge style make it compatible with standard drill press and CNC setups. Machinists, tool-and-die makers, and fabrication shops are the primary users.

This combo drill countersink is rated for use in demanding workpiece materials including steel, stainless steel, hardened steel, cast iron, and special alloys. The double end type doubles tool life before replacement is needed. It is well suited to production and maintenance environments where countersinking into tough ferrous materials is routine. The solid carbide construction maintains cutting-edge integrity at elevated temperatures and feeds that would wear out high-speed steel tooling. Applications include countersinking fastener seats, deburring drilled holes, and preparing surfaces for flat or oval-head fasteners in structural and precision machined components.

Key Features

• Solid carbide construction for superior hardness and wear resistance in ferrous and hard alloy materials
• 60-degree included angle produces accurate countersunk seats for standard fasteners
• Double end design extends usable tool life before replacement
• Bright polished finish minimizes friction and promotes chip flow
• Long-length tool at 5 inches overall for extended reach applications
• Right-hand cut, plain cutting edge - compatible with standard CNC and manual spindles

Compatibility

Rated for primary and secondary workpiece materials including steel, stainless steel, hardened steel, cast iron, and special alloys. Series 405 design. Sized for standard tool holders and collets accepting a 7/16-inch shank body.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians. Ensure the tool holder and spindle are fully powered down and locked out before mounting or removing the tool. Secure the tool firmly in a collet or chuck rated for the body diameter before operation. Follow the machine manufacturer and tooling manufacturer feed and speed recommendations for the specific workpiece material to avoid premature edge chipping in carbide tooling.
