Machine tap FANAR M4 extended — model F1-151001-0040

FANAR extended machine tap M4 (model F1-151001-0040) is a precision cutting tool designed for producing internal M4 threads in metal and other machinable materials. Intended for machine tapping operations, this extended-length tap provides the additional reach required for deep holes, recessed locations or parts with limited access. The tool is suitable for use in lathes, milling machines and CNC machining centers where consistent thread form and repeatable results are required.

Advantages

The extended shank delivers increased reach without sacrificing rigidity, enabling accurate thread production at greater depths. Manufactured to FANAR quality standards, the tap offers consistent geometry for reliable thread profile and repeatability across production runs. Its design facilitates stable chip evacuation and reduces the need for frequent tool changes in recessed tapping applications.

Suitable for

• Producing M4 internal threads in metals such as steel, aluminium and brass
• Tapping deep or recessed holes where standard-length taps cannot reach
• Machine tapping operations on lathes, milling machines and CNC machining centers
• Batch production and repair operations requiring repeatable thread quality

Key specifications

• Thread size: M4 internal thread
• Tool type: machine tap with extended reach
• Intended materials: machinable metals (steel, aluminium, brass) and similar materials
• Application: designed for machine tapping (lathe, mill, CNC)
• Geometry: precision ground for consistent thread form and repeatability

How to use

Mount the tap in a suitable machine tap holder or collet with proper axial alignment to prevent bending and ensure concentricity. Select appropriate spindle speed and feed for the workpiece material, and apply a suitable cutting fluid to improve tool life and chip evacuation. Advance the tap under controlled feed, retracting periodically if required for chip clearance in deep holes. Inspect produced threads for correct depth and profile after machining.

Usage recommendations

Use correct spindle speed and feed values for the specific workpiece material, ensure secure clamping and alignment, and employ appropriate cutting fluid to extend tool life. For interrupted cuts or hardened materials consider pre-drilling and selecting a suitable tap geometry or coating compatible with the workpiece.
