Machine tap FANAR M4 (model A1-230001-0040) for cutting metric internal threads

FANAR machine tap M4 (model A1-230001-0040) is a precision cutting tool engineered to produce M4 metric internal threads in metals and other compatible materials. Designed for machine tapping operations, the tap delivers a consistent thread profile suitable for assembly with M4 screws and fasteners. It is intended for industrial production and workshop use where repeatability and dimensional accuracy are important.

Advantages

The FANAR machine tap M4 provides accurate thread geometry and uniform results across repeated cycles. Its design supports stable cutting action in machine-operated tapping processes, reducing the need for manual rework. The tool is compatible with common tapping equipment and fixtures used in industrial and workshop settings.

Suitable for

• Producing M4 metric internal threads in steel, aluminum, and similar machinable materials
• Batch production on tapping machines, CNC machines, and dedicated tapping heads
• Repair and maintenance tasks requiring replacement or creation of M4 threaded holes
• Workshop and industrial applications where consistent thread form is required

When it may not be suitable

This tap is intended specifically for M4 metric internal threads; it is not appropriate for other thread diameters or non-metric systems. It may not be suitable for extremely hard or abrasive materials without using a specialized grade or coating of tap intended for such materials. Hand tapping with incompatible holders or improper alignment can lead to poor thread quality or tap breakage.

Key specifications

• Thread size: M4 metric internal thread
• Tool type: machine tap for powered tapping operations
• Intended materials: metals and other machinable materials (e.g., steel, aluminum)
• Typical use: production and workshop tapping for assembly with M4 fasteners

How to use

Mount the machine tap in a rigid tapping spindle, tapping head, or suitable collet holder that provides accurate axial alignment. Select the correct drill size for the M4 thread before tapping and secure the workpiece to prevent movement. Use appropriate cutting fluid to improve chip evacuation and reduce wear. Operate at the recommended spindle speed and feed rate for the material being machined, and use synchronous tapping or a floating tapping head as required to match spindle rotation and avoid excessive torque. Inspect threaded holes for correct form and fit with M4 fasteners after tapping.

What to consider before purchase

• Confirm that M4 thread size matches your application requirements
• Verify compatibility with your machine holder or tapping head
• Consider material to be tapped and whether a coated or special-material tap is required
• Ensure correct drill size and cutting fluid are available for the intended material

Usage recommendations

For best results, use the tap in properly aligned machine tapping equipment, maintain recommended speeds and feeds for the workpiece material, and apply suitable cutting fluid. Replace the tap when wear or damage degrades thread quality to maintain consistent assembly fit for M4 fasteners.
