M.a. Ford. 40423620 Solid Carbide Spotting Drill 6mm

Product Description

The M.A. FORD. 40423620 is a solid carbide spotting drill designed to accurately locate and start holes before a twist drill or reamer follows through. Built to Series 404 standards, it features a 90-degree drill point angle, a 6mm cutting diameter (0.2362 inches), and an overall length of 51mm (2.008 inches). The bright/uncoated finish makes it well suited for general-purpose spotting operations across a range of workpiece materials. Machinists and toolroom professionals use this drill in CNC machining centers, mills, and drill presses where precise hole location is critical before follow-on operations.

This spotting drill is intended for general-purpose metalworking and machining applications. With a 26mm (1.024-inch) spiral flute length and a straight-cylindrical shank, it seats securely in standard collets and drill chucks. The 90-degree included angle aligns with the most common follow-on drill point geometry, minimizing walk-off and keeping hole position within tight tolerances. It is used in job shops, production environments, and toolroom settings handling ferrous and non-ferrous materials.

Key Features

• Solid carbide construction for rigidity and wear resistance during spotting operations
• 90-degree drill point angle matches common twist drill geometry to reduce hole walk-off
• 6mm cutting diameter with a matching 6mm straight-cylindrical shank for secure chuck or collet seating
• 26mm spiral flute length with a 21-degree helix angle for controlled chip evacuation
• Bright/uncoated finish suitable for general-purpose applications across a broad material range
• Right-hand cut, single-ended design for standard CNC and manual machine setups

Compatibility

Designed as an OEM-style general-purpose spotting drill compatible with standard ER collet chucks, Weldon-shank adapters, and keyed or keyless drill chucks accepting a 6mm straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist. Secure the straight-cylindrical shank fully into the collet or chuck to the recommended engagement depth before tightening. Confirm spindle speed and feed rate settings are appropriate for the workpiece material and carbide tooling before initiating the cut. Avoid side loading or using this tool for plunge milling operations outside its rated spotting application.
