Machine Tap FANAR 1/4" model D2-121101-4627 for threading

FANAR machine tap 1/4" model D2-121101-4627 is a precision cutting tool designed for creating internal threads in pre-drilled holes. Made for machine use, the tap delivers accurate 1/4" threading suitable for a range of metalworking tasks. The tool is intended to operate at appropriate spindle speeds and with recommended cutting fluids to ensure clean threads and prolonged tool life.

Advantages

The machine tap offers consistent thread form and dimensional accuracy when used in suitable machine setups. Its design supports efficient chip evacuation and reduced thread distortion under correct feed and lubrication. The tool is compatible with standard machine tap holders and can be used in production, repair and maintenance contexts where repeatable, reliable internal threads are required.

Suitable for

• Producing 1/4" internal threads in steel and non-ferrous alloys
• Workshop repair and maintenance operations
• Series production and small-batch manufacturing
• Threading in pre-drilled holes on lathes, milling machines and tapping heads

Key specifications

• Thread size: 1/4" (as indicated by the tool marking)
• Tool type: machine tap for internal threading
• Application: metalworking (suitable for steels and common alloys with correct cutting fluid)
• Intended use: machine tapping in production or workshop environments
• Shank/drive: machine-compatible configuration (for use with standard holders/chucks)

How to use

Secure the workpiece and confirm hole diameter and depth match the thread requirements. Fit the tap into a suitable machine holder or tapping head and set the spindle speed and feed according to material and tap specifications. Apply appropriate cutting fluid to the work area to reduce friction and improve chip removal. Engage the tap carefully, maintaining a consistent feed; for through holes use continuous forward motion and for blind holes use incremental feed with periodic reverse motion to clear chips. After threading, retract the tap and clean the thread and tool to remove chips and coolant residues.

Usage recommendations

Use recommended cutting fluids for the material being machined, monitor spindle speed and feed to avoid overloading the tap, and inspect threads after cutting to verify dimensional accuracy. For hardened materials or interrupted cuts, consider using lubricants formulated for heavy-duty tapping and check tool condition regularly.
