FANAR machine tap M4 (model C2-521701-0040) is a dedicated cutting tool for producing internal M4 metric threads in machine tapping and CNC operations. Designed by FANAR for use in industrial and workshop environments, this tap supports precision threading of metal components, enabling accurate screw and fastener engagement during assembly and repair tasks.
Advantages
The FANAR M4 machine tap is engineered to deliver consistent thread form and dimensional accuracy when used in appropriate tapping machines or CNC setups. Its geometry and cutting edges are optimized for metalworking applications, providing reliable chip evacuation and repeatable performance across multiple cycles. The tool's construction is intended to withstand standard industrial tapping conditions, helping maintain thread quality and reduce rework.
Suitable for
- Cutting internal M4 metric threads in steels and other common metals when using machine tapping or CNC equipment
- Production runs and workshop jobs requiring repeatable, accurate M4 threads
- Component assembly and fastener preparation where precise internal threading is needed
When it may not be suitable
This machine tap is intended specifically for M4 metric thread cutting in machine or CNC applications and may not be suitable for manual hand-tapping tasks or materials outside standard metalworking ranges. For materials with exceptional hardness, brittle characteristics, or specific coatings, a specialized tap geometry or material-grade tool may be required.
Key specifications
- Thread size: M4 (metric)
- Tool type: machine tap for internal thread cutting
- Intended use: machine tapping, CNC tapping operations
- Application: metalworking for component assembly and fastener preparation
How to use
Mount the FANAR M4 machine tap in a suitable tapping machine or CNC spindle with the correct collet or holder. Ensure workpiece material is securely clamped and properly centered. Use recommended cutting speeds, feeds, and appropriate cutting fluid for the material being machined. Engage the tap with steady axial feed, monitor chip formation and evacuation, and retract as needed to clear chips. Follow safety procedures and machine manufacturer guidelines during operation.
What to consider before purchase
- Confirm you require an M4 internal metric tap for machine or CNC use, not a hand tap
- Check compatibility with your tapping machine or CNC tool holder and spindle size
- Verify the materials you will cut and ensure the tap geometry and grade are appropriate for those metals
- Plan for correct cutting speeds, feeds, and coolant to maximize tool life and thread quality
Usage recommendations
Use appropriate cutting fluid, maintain stable machine setup, and perform regular inspection of the tap for wear. Replace the tap when thread quality declines to prevent damage to workpieces and ensure consistent production of M4 threads.
