M.a. Ford. 40431500 Solid Carbide Spotting Drill 8mm

Product Description

The M.A. FORD. 40431500 is a solid carbide spotting drill designed to establish precise starter holes for follow-on drilling operations in metalworking applications. Built to Series 404 standards, it features a 90-degree drill point angle and an 8mm cutting diameter (0.3150 inches), making it well suited for accurate spot drilling on flat or angled surfaces. The tool is uncoated with a bright finish and is configured for right-hand cutting. Licensed machinists, tool-and-die makers, and CNC operators typically install and run this tool on drill presses, machining centers, and CNC turning equipment.

This spotting drill is intended for general-purpose spotting applications in production and job-shop environments. With a 26mm flute length (1.0236 inches), a 64mm overall length (2.5197 inches), and a straight-cylindrical shank matching the 8mm cutting diameter, it seats cleanly in standard collet or drill chuck toolholding. The spiral flute geometry with a 21-degree helix angle promotes chip evacuation during spotting cycles.

Key Features

• 90-degree drill point angle for accurate center location and chamfering
• Solid carbide construction provides rigidity and wear resistance in metalworking operations
• Bright/uncoated finish suitable for general-purpose spotting on a range of workpiece materials
• Two-flute spiral design with 21-degree helix angle for controlled chip flow
• Straight-cylindrical shank fits standard collet chucks and drill chucks without adapters
• Single-ended tool for straightforward setup and tool-length offset entry

Compatibility

Designed as an OEM-style general-purpose spotting drill compatible with standard straight-shank toolholding systems on drill presses, vertical machining centers, and CNC mills accepting 8mm shank diameter tooling.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC programmers following established shop safety procedures. Ensure the spindle is fully stopped and locked out before loading or removing the tool from the holder. Seat the straight-cylindrical shank fully into the collet or chuck and verify runout before beginning a spotting cycle. Refer to the machine manufacturer guidelines and applicable OSHA machining safety standards for speeds, feeds, and coolant use.
