Hand Tap Set FANAR M4 metric, manual gwintownik komplet, model A1-220001-0040

FANAR hand tap set for M4 metric threads is a manual gwintownik komplet designed for cutting standard M4 internal threads by hand. The set includes the sequence of taps needed to form M4 threads in through and blind holes and is suitable for use on common workshop materials such as metals and plastics where manual tapping is appropriate. Compact and intended for maintenance, repair and small-scale workshop tasks, this FANAR set provides the basic tools required to produce reliable M4 threads without power tools.

Advantages

The FANAR M4 hand tap set offers a straightforward, tool-based solution for creating M4 internal threads using hand tapping techniques. The set is compact for easy storage and transport and allows controlled cutting for accurate thread formation in both through and blind holes. Because it is designed for manual use, it reduces the risk of overheating or material damage that can occur with high-speed power tapping, and it is suitable for workshop repairs and maintenance where electric tools are not available or not desirable.

Suitable for

• Creating M4 internal threads in metal components
• Tapping M4 threads in plastic parts
• Maintenance and repair work in workshops and garages
• Small-scale production or prototype assembly requiring manual tapping
• Field service tasks where portable hand tools are needed

Key specifications

• Thread size: M4 metric
• Type: manual hand tap set for forming standard internal threads
• Intended hole types: through holes and blind holes
• Material suitability: common metals and plastics (manual tapping)
• Use: manual operation with compatible tap wrench or holder

How to use

Select the appropriate starting tap from the set and secure the workpiece to prevent movement. If required, drill the hole to the correct pre-tap diameter for M4 threads. Mount the tap in a suitable T-handle or tap wrench and align it square to the hole. Apply cutting lubricant appropriate for the workpiece material, then turn the tap clockwise in small, steady increments, backing off periodically to clear chips. For blind holes, avoid forcing the tap to the bottom; use incremental cuts and chip clearing to prevent breakage. After reaching full depth, reverse the tap to remove it and clean the threaded hole and taps before storage.

Usage recommendations

Use suitable cutting lubricant when tapping metals to improve chip evacuation and extend tap life; for plastics use light pressure and slower feed to avoid melting or deformation. Always match the pre-drill size to M4 thread standards and use steady, controlled turns with periodic reverse motion to clear chips and reduce tap stress.
