Machine Tap FANAR 1/2" model D2-111101-4131 — threaded tool for cutting internal threads

FANAR machine tap 1/2" model D2-111101-4131 is a cutting tool intended for producing internal 1/2" threads in metal or compatible materials. Designed for machine tapping operations, the tool delivers repeatable thread forming and cutting suitable for assembly, maintenance, and repair tasks in industrial and workshop environments. The tap is compatible with standard machine tapping systems and is intended for use where precise internal 1/2" threads are required.

Advantages

The FANAR 1/2" machine tap provides accurate thread geometry and consistent performance during serial machining. Manufactured to tight dimensional tolerances, it ensures reliable fit with mating fasteners and reduces the need for rework. Its design supports efficient chip evacuation and stable cutting action when used with appropriate machine settings and lubrication, which helps prolong tool life and maintain thread quality over multiple cycles.

Suitable for

• Producing internal 1/2" threads in steel, cast iron, aluminum alloys and other machinable metals
• Machine tapping operations on lathes, milling machines with tapping attachments, and dedicated tapping machines
• Industrial production runs, repair and maintenance tasks, and workshop fabrication

Key specifications

• Thread size: 1/2" internal thread
• Tool type: machine tap for cutting internal threads
• Application: intended for metal machining and compatible materials
• Use mode: designed for machine tapping (not manual hand-tapping)
• Compatibility: suitable for standard machine tapping setups and fixtures

How to use

Mount the tap securely in the machine's collet or tap holder, ensuring alignment with the workpiece axis. Select appropriate spindle speed and feed for the material being machined and use recommended cutting fluid to aid chip evacuation and reduce heat. Engage the tap using the machine's tapping cycle or appropriate feed control, reversing or using a retract cycle as needed to break and clear chips. Inspect the formed threads after tapping and perform any required cleaning or deburring before assembly.

Usage recommendations

For best results, match cutting speed and feed to the workpiece material, maintain proper coolant or lubricant flow, and ensure the tap is correctly aligned with the hole axis. Replace the tap when wear or damage affects thread quality. When tapping blind holes, allow for chip clearance and use peck tapping cycles if available to prevent chip packing.
