M.a. Ford 40425000 Solid Carbide Spotting Drill 90 Deg

Product Description

The M.A. FORD 40425000 is a solid carbide spotting drill designed to create precise center-start locations for follow-on drilling operations. Built to a 90-degree drill point angle with a 0.2500-inch cutting diameter and a 2-inch overall length, this tool delivers accurate spot positioning on ferrous and non-ferrous materials. The bright, uncoated finish suits general-purpose work where additional coating is unnecessary or where regrinding is anticipated. With two spiral flutes and a 21-degree helix angle, it evacuates chips efficiently at the start of the hole cycle. Licensed machinists and CNC operators in production and job-shop environments rely on this Series 404 tool for consistent drill-point registration before boring or deep-hole drilling.

This spotting drill is suited for general-purpose machining centers, manual mills, and drill press applications in both production and maintenance environments. The straight-cylindrical shank accommodates standard collet chucks and drill chucks without special tooling adapters. Single-ended configuration makes it straightforward to load and set tool length offsets. It performs across a broad range of workpiece materials, including steels, aluminum alloys, and plastics, wherever a clean, properly angled starting point is required before a twist drill or insert drill engages the workpiece.

Key Features

• 90-degree drill point angle matches the included angle of most standard twist drills for accurate drill-point registration
• Solid carbide construction provides rigidity and wear resistance superior to high-speed steel in demanding applications
• Bright, uncoated finish allows easy visual inspection of cutting edges and supports regrinding
• Two spiral flutes with a 21-degree helix angle promote chip clearance at hole entry
• Straight-cylindrical shank fits standard collet and drill-chuck toolholders without adapters
• Series 404 general-purpose designation covers a wide range of workpiece materials and machine types

Compatibility

Designed as a general-purpose spotting drill compatible with standard collet chucks and drill chucks accepting a 0.2500-inch straight-cylindrical shank on CNC machining centers, manual knee mills, and drill presses.

Installation Notes

Installation is typically performed by a machinist or CNC operator. Secure the shank fully within the collet or chuck to the recommended engagement depth to prevent tool pullout under thrust load. Set spindle speed and feed rate per the machine tool builder and carbide tooling guidelines for the workpiece material before engaging the cut. Inspect cutting edges for chipping or wear before each setup, as carbide is brittle and edge damage can propagate rapidly if the tool is run in a compromised state.
