Tap, FANAR M4 machine tap C2-111101-0040, metric M4 thread

FANAR machine tap M4 (metric M4 thread) is a precision cutting tool designed for creating internal M4 metric threads in a range of materials. Intended for machine tapping operations, this tap is suitable for both CNC and manual tapping equipment used in industrial and workshop settings. The tool is engineered to deliver consistent thread form and dimensional accuracy for standard M4 fastening applications.

Advantages

The FANAR M4 machine tap provides reliable performance through precise geometry that supports stable chip evacuation and reduced risk of tool breakage during machine tapping. Its design focuses on consistent thread quality and repeatability across batches, which helps maintain assembly tolerances. The tap is compatible with common machine setups and offers efficient productivity for repeated thread cutting tasks.

Suitable for

• Cutting internal metric M4 threads in metals and metal alloys
• Machine tapping operations on CNC machines
• Manual tapping in workshop lathes and tapping heads
• Precision assembly and repair tasks requiring standard M4 threads

Key specifications

• Thread form: Metric M4
• Application: Machine tapping (CNC and manual)
• Intended use: Internal thread cutting
• Material compatibility: Suitable for common metals and metal alloys used in industrial settings
• Design focus: Precision thread geometry and chip control

How to use

Secure the workpiece and align the tool holder or tapping head to ensure the tap enters perpendicular to the work surface. Use appropriate spindle speed and feed settings for M4 thread cutting, and apply cutting fluid when machining metals to improve chip evacuation and reduce heat. For blind holes, periodically reverse the tap or withdraw to clear chips. Follow machine manufacturer guidelines for clamping and torque limits to minimize risk of tap breakage.

Usage recommendations

Choose cutting speeds and feeds based on the workpiece material; use cutting oil or coolant for steel and alloys, and lighter lubrication for softer materials. Inspect taps regularly for wear or damage and replace when thread quality declines. For critical assemblies, verify thread fit with appropriate gauges before final assembly.
