M.a. Ford. 40339370 Solid Carbide Spotting Drill 10mm

Product Description

The M.A. FORD. 40339370 is a solid carbide spotting drill designed to create accurate pilot spots and chamfers before through-hole drilling operations. Built to Series 403 standards, this tool features a 120-degree drill point angle, a 10mm cutting diameter (0.3937 inches), and a 70mm overall length (2.7559 inches). The bright/uncoated finish keeps the carbide substrate exposed for general-purpose use across a range of workpiece materials. Machinists, tool-and-die makers, and CNC operators install this drill in machining centers and drill presses where precise hole location and consistent entry angles are required before final drilling.

This spotting drill is suited for general-purpose metal removal in production and job-shop environments. The 10mm straight-cylindrical shank seats directly in standard ER collets, drill chucks, or hydraulic holders without modification. Its 30mm flute length (1.1811 inches) and 2-flute spiral geometry allow chips to clear efficiently at the shallow depths typical of spotting operations. The single-ended design is standard for this tool class, and the right-hand cutting direction is compatible with conventional CNC and manual spindle rotation.

Key Features

• 120-degree point angle for accurate spot drilling and chamfering before finish drilling
• Solid carbide construction for rigidity and wear resistance in general-purpose machining
• 10mm straight-cylindrical shank (0.3937 inches) fits standard collet and chuck tooling
• 2-flute spiral geometry with 21-degree helix angle promotes efficient chip evacuation
• Bright/uncoated finish suitable for dry cutting or use with cutting fluid
• Right-hand cut, single-ended design compatible with standard spindle rotation

Compatibility

Designed as an OEM-style general-purpose spotting drill for use in CNC machining centers, drill presses, and manual mills where a 10mm straight-cylindrical shank tool is required. Part of the M.A. FORD. Series 403 spotting drill family.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or CNC programmers familiar with carbide tooling best practices. Secure the shank fully within the collet or chuck to the recommended grip depth before running the spindle. Confirm spindle rotation is set to right-hand before engaging the cut. Solid carbide tools are brittle compared to high-speed steel — avoid lateral loading, interrupted cuts without proper feed reduction, or dropping the tool on hard surfaces.
