Machine Tap FANAR 4 mm C4-118M01-0040 — metric machine threading tool 4.0 mm

FANAR machine tap C4-118M01-0040 is a metric machine threading tool for producing internal threads with a nominal diameter of 4.0 mm. Intended for machine tapping operations, this tap is made for use in production environments and workshops where consistent thread geometry and repeatability are required. It is compatible with standard machine holders and is designed to cut metric threads to specification in a range of common engineering materials.

Advantages

The machine tap provides accurate thread profiles and stable performance during continuous operation. Its geometry is optimized for reliable chip formation and evacuation in normal tapping conditions, reducing the risk of tap breakage and improving process repeatability. The tool is suitable for use in automated and manual machine tapping processes and offers dependable dimensional accuracy for mating fasteners.

Suitable for

• Creating internal metric M4 threads in metal components
• Production-line machine tapping operations
• Workshop and maintenance threading tasks
• Batch and single-piece machining where standard machine holders are used

Key specifications

• Thread type: metric internal thread
• Nominal diameter: 4.0 mm
• Tool form: machine tap for use in machine holders
• Intended application: metalworking and machining operations
• Design focus: reliable chip evacuation and consistent thread geometry

How to use

Install the tap securely in a suitable machine holder and verify alignment with the workpiece. Select appropriate cutting speed, feed, and lubrication based on the workpiece material and machine capabilities. Advance the tap into the pre-drilled hole to the required thread depth, using controlled feed and reversing as needed to break and clear chips. Inspect the thread after tapping for correct form and fit, and remove any chips or burrs before assembly.

Usage recommendations

For best results, use proper cutting fluid suited to the material being tapped, maintain correct spindle speed and feed, and ensure the hole diameter matches the recommended tap drill for M4 threads. Regularly inspect the tap for wear and replace it when thread quality begins to degrade to maintain consistent production quality.
