M.a. Ford. 40347240 Solid Carbide Spotting Drill 12mm

Product Description

The M.A. FORD. 40347240 is a solid carbide spotting drill designed to create precise starter points for follow-on drilling operations. Built to a 120-degree drill point angle, the tool establishes accurate center locations that guide twist drills and reduce walking on entry. The 12mm cutting diameter and 76mm overall length suit a wide range of workpiece thicknesses. With a bright/uncoated finish and two spiral flutes, this drill runs efficiently on general-purpose spotting applications where coating is not required. A straight-cylindrical shank and right-hand cutting direction make it compatible with standard drill chucks and collet systems used in production and job-shop environments.

This spotting drill is intended for metalworking applications in machining centers, CNC mills, and drill presses. The 21-degree helix angle and spiral flute geometry promote chip evacuation and help maintain clean entry geometry. Series 403 spotting drills are used by machinists, toolmakers, and production operators working with steel, aluminum, cast iron, and similar materials where consistent hole location is critical before reaming or tapping.

Key Features

• 120-degree drill point angle for accurate center-starting on follow-on drill operations
• Solid carbide construction provides rigidity and wear resistance across general-purpose materials
• Bright/uncoated finish suitable for use with cutting fluids on a broad range of workpiece materials
• Two spiral flutes with 21-degree helix angle aid chip clearance during spotting
• Straight-cylindrical shank fits standard ER collets and drill chucks without adapter hardware
• Right-hand cut, single-ended design for straightforward setup in conventional spindle configurations

Compatibility

Designed as a general-purpose OEM-style spotting drill for use in CNC machining centers, knee mills, and drill presses equipped with standard straight-bore collet or chuck tooling systems accepting a 12mm shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the drill from the chuck or collet holder. Confirm runout and axial alignment with an indicator before beginning production cuts to protect the carbide from chipping due to misalignment. Follow applicable shop safety protocols and machine manufacturer guidelines for spindle speed and feed rate selection.
