Machine tap FANAR M12 extended (model D2-511121-0120)

Extended machine tap FANAR M12 (model D2-511121-0120) is a precision tool designed for cutting internal metric M12 threads. It is intended for use in machining centers and tapping machines where an extended reach is necessary to access deeper holes or recessed workpieces. The tap is made to deliver consistent thread geometry for standard M12 threads in metalworking and maintenance operations that require accurate internal thread cutting.

Advantages

The extended length provides improved access to deep or hard-to-reach holes without the need for special extensions. Manufactured by FANAR with attention to dimensional accuracy, the tap offers reliable thread form and repeatability in production environments. Its design balances rigidity and clearance to reduce the risk of tap breakage and support smooth chip evacuation during tapping operations.

Suitable for

• Cutting internal M12 metric threads in steel, cast iron and non-ferrous metals
• Use in machining centers and CNC tapping machines requiring extended-reach tooling
• Repair and maintenance tasks where threads are located in recessed or deep holes
• Batch production where consistent M12 thread quality and repeatability are required

Key specifications

• Thread size: M12 metric
• Tool type: machine tap, extended length
• Intended application: internal thread cutting in metalworking
• Compatibility: suitable for machining centers and tapping machines
• Design features: extended reach for deep or recessed holes; geometry for chip control and reduced breakage risk

How to use

Mount the tap securely in the machine spindle or tapping holder specified for machine taps. Align the tool with the hole axis and ensure correct feed and spindle speed according to the material being tapped. Use appropriate cutting fluid to aid chip evacuation and tool life. When tapping deep holes, retract periodically if recommended by the machine or process to clear chips and avoid jamming. Follow standard safety procedures and machine manufacturer guidelines during setup and operation.

Usage recommendations

For best results, select cutting speeds and feeds based on the workpiece material and use suitable coolant. Inspect holes for correct diameter and alignment before tapping, and consider pre-drilling with the recommended pilot size for M12 threads. In automated or high-volume processes, monitor tool wear and replace the tap when thread quality declines to maintain consistent production output.
