Machine tap FANAR M4 C2-511121-0040 – metric M4 cutting tool for threaded holes

FANAR machine tap M4 (model C2-511121-0040) is a metric M4 cutting tool designed for producing accurate internal threads in metalworking. Engineered for machine tapping operations, this tap creates standard M4 threads in a variety of materials commonly used in mechanical workshops and production environments. The tool is suitable for repetitive machining tasks where consistent thread geometry and surface finish are required.

Advantages

The tap delivers precise thread form and dimensional accuracy compatible with metric M4 specifications, reducing rework and ensuring interchangeable threaded connections. Manufactured to industrial tolerances, it offers reliable cutting performance in machine-driven tapping processes. Its geometry facilitates chip evacuation and stable engagement with the workpiece, contributing to consistent results across batches.

Suitable for

• Machine tapping on lathes, milling machines, and CNC tapping heads
• Batch production of M4 threaded components
• Repair and maintenance of mechanical assemblies requiring M4 threads
• Workshop and toolroom use where controlled, repeatable tapping is needed

Key specifications

• Thread type: metric M4 internal thread
• Tool function: machine tap for creating threaded holes
• Intended use: machine tapping operations
• Applicable materials: common metals used in mechanical engineering (steel, aluminum, brass) depending on machining parameters
• Geometry features: designed for chip control and stable cutting engagement

How to use

Install the tap in a suitable machine tapping holder, collet, or spindle designed for the chosen machine tool. Select appropriate cutting speed, feed, and lubrication based on workpiece material and machine manufacturer recommendations. Align the tap accurately with the drilled pilot hole sized for an M4 thread, then engage the tap under controlled feed to cut the thread. For blind holes, monitor chip evacuation and use pecking or periodic reversing if required; for through holes, ensure chips clear freely. Inspect the threaded hole with a gauge or mating fastener to confirm fit and thread quality.

Usage recommendations

Use cutting fluid suitable for the workpiece material to extend tool life and improve surface finish. Ensure the pilot hole diameter matches M4 tapping standards and maintain correct spindle alignment to avoid tool breakage. For mass production, verify process parameters and tool condition regularly to maintain consistent thread dimensions.
