Machine Tap FANAR M4 — model C4-115001-0040

Machine tap FANAR M4 — model C4-115001-0040 is a precision cutting tool designed to form M4 metric threads in through and blind holes during machine tapping operations. Manufactured by FANAR for use on standard tapping machines and machining centers, this tap is intended for production, maintenance and repair environments that require consistent and accurate M4 threads in metallic materials. The tool’s geometry and manufacturing tolerances deliver repeatable thread form and proper fit for M4 fasteners.

Advantages

The FANAR M4 machine tap provides stable machining performance, consistent thread quality and dimensional accuracy tailored to M4 metric fasteners. Its construction supports reliable engagement with machine spindles and fixtures, while the cutting geometry reduces cutting forces and improves chip evacuation in typical metalworking materials. The tap’s design helps extend tool life under appropriate operating conditions and facilitates repeatable results in batch production.

Suitable for

• Creating M4 metric internal threads in steel, stainless steel and non-ferrous metals (with suitable machining parameters)
• Machine tapping operations on tapping heads or CNC machining centers
• Production runs, maintenance and repair tasks requiring uniform thread quality
• Applications where precision M4 thread fit and repeatability are required

Key specifications

• Thread size: M4 metric
• Intended use: machine tapping (not hand tapping)
• Suitable materials: common metals (steel, stainless steel, aluminum and other non-ferrous alloys) when proper speeds, feeds and lubrication are used
• Geometry: precision ground/cut profile for accurate thread form
• Compatibility: designed for standard machine tapping spindles and fixtures

How to use

Secure the workpiece and ensure correct alignment between the tap and the hole axis. Drill the hole to the recommended core diameter for an M4 thread, then mount the FANAR M4 machine tap into the machine tapping tool holder or spindle. Select appropriate spindle speed, feed and coolant or lubrication based on the workpiece material and tap geometry; follow standard machinist reference data for M4 taps. Engage the tap with steady axial feed, allow proper chip evacuation, and reverse or break off chips as required by the tapping cycle. Inspect produced threads for dimensional accuracy and surface condition and adjust parameters if necessary.

Usage recommendations

Use cutting fluid suitable for the workpiece material, maintain correct hole size and alignment, and follow machine manufacturer guidance for tapping cycles to maximize tool life and thread quality.
