Thread Tap Art-Pol M4 x 0.7 mm, Hand/Machine Tap, Metric M4x0.7

Art-Pol thread tap M4 x 0.7 mm is a metric hand/machine tap designed to cut internal M4 threads with a 0.7 mm pitch in metal and plastic. Intended for both manual and machine tapping operations, this tap supports repair, maintenance, and assembly tasks where reliable M4 fastening is required. The tool is suitable for creating new threads or restoring damaged threads in components used in general mechanical work and light fabrication.

Advantages

The tap provides precise thread geometry for consistent M4 connections and is compatible with standard tapping practices for metric threads. Its design allows use in hand-held tap wrenches as well as in machine tapping setups, offering flexibility between manual and automated workflows. The tool is appropriate for work on a range of materials, including common steels and plastics, ensuring broad applicability in workshops and for field repairs.

Suitable for

• Cutting new internal M4 x 0.7 threads in metal and plastic
• Repairing or restoring damaged M4 threads on components
• General mechanical assembly and maintenance tasks requiring M4 fasteners
• Small-scale fabrication and prototype work where metric M4 threads are needed

Key specifications

• Thread size: M4
• Thread pitch: 0.7 mm
• Intended use: hand and machine tapping
• Material compatibility: metals and plastics (general-purpose)
• Application: internal thread cutting and thread restoration

How to use

Select an appropriate pilot hole for M4 x 0.7 threads, align the tap perpendicular to the workpiece, and begin cutting using steady, controlled pressure. For hand use, turn the tap clockwise to cut and periodically reverse a half-turn to break chips and clear swarf. When using a tapping machine, set correct spindle speed and feed to match the material and lubrication. Use suitable cutting fluid for metals to improve chip evacuation and extend tool life; for plastics, reduce speed and avoid excessive feed to prevent cracking or melting.

Usage recommendations

Use the tap with correct pilot hole diameter and appropriate lubrication for the workpiece material. Inspect tapped threads for burrs and clean swarf from the hole before assembly. For precision assemblies, verify thread fit with an M4 screw; replace the tap if wear degrades thread quality.
