Hand Tap Set FANAR M4, 3 pieces (A4-235D51-0040)

FANAR hand tap set for cutting internal metric threads M4 includes three taps designed for manual use. The set provides a standard progressive sequence—typically taper, second, and plug taps—to form or repair M4 threads in metals and plastics. Compact and lightweight, this hand tap set is intended for tasks where hand tapping is preferred or required, such as maintenance, small-scale fabrication and on-site repairs.

Advantages

The FANAR M4 hand tap set offers a complete progression of taps to reduce cutting forces and minimize thread damage during manual operation. Hardened cutting edges and a consistent thread profile ensure repeatable, accurate thread creation. The compact three-piece format simplifies storage and selection for sequential use and is suitable for both occasional repairs and routine workshop work.

Suitable for

• Creating new M4 internal threads in metal or plastic components
• Repairing damaged or worn M4 threads
• Manual, hand-operated tapping where power tapping is not feasible
• Maintenance tasks, prototypes and small fabrication projects

Key specifications

• Thread size: M4 metric internal threads
• Number of pieces: 3 taps (progressive sequence for manual cutting)
• Intended use: manual hand tapping
• Materials: suitable for use in common metals and plastics (manual tapping applications)
• Design: standard straight flute geometry for chip evacuation during hand operation

How to use

Select the appropriate tap from the set and clamp the workpiece securely. Use a suitable tap wrench to align the tap perpendicular to the hole and start cutting with the taper tap to establish the thread. Progress to the middle tap and then the plug tap to complete the thread profile, using short clockwise advances and occasional counter-clockwise backing to break chips. Apply cutting fluid as needed to reduce friction and improve finish, and remove the taps carefully after completing the thread.

Usage recommendations

For best results, drill the hole to the correct size for M4 internal threads, secure the workpiece, and use light, steady pressure with proper alignment. Use cutting fluid for metal applications and clear chips frequently to prevent tap breakage. Store the taps in a dry place to avoid corrosion.
