Machine Tap FANAR 1/4" Whitworth / Imperial Thread D2-121101-3327

FANAR machine tap for 1/4" Whitworth / imperial thread is a cutting tool designed for creating standardized internal threads in metal components during machine tapping operations. It is intended for use in production and repair workshops where accurate, repeatable thread forms in imperial (Whitworth-style) dimensions are required. The tap is suitable for installation in tapping heads, milling machines, or dedicated tapping machines and is produced by FANAR for industrial applications.

Advantages

The tap delivers a consistent Whitworth-profile internal thread with close dimensional conformity to 1/4" imperial specifications. It is manufactured to industrial tolerances for reliable interchangeability and repeatability in serial or single-item machining. The design supports machine-driven tapping, providing stable cutting behavior and predictable chip evacuation when used with appropriate speeds and lubricants. The tool’s construction allows it to withstand workshop conditions typical of metalworking environments.

Suitable for

• Producing 1/4" Whitworth internal threads in steel, cast iron, and non-ferrous metals (where thread form and tool selection are appropriate)
• Machine tapping in tapping heads, CNC milling machines, and manual tapping machines
• Repair and maintenance tasks requiring replacement or re‑tapping of imperial-threaded bores

Key specifications

• Thread form: Whitworth-style (imperial) 1/4"
• Intended use: machine tapping operations
• Suitable materials: common workshop metals including steel, cast iron, and non-ferrous alloys (subject to proper coolant and cutting parameters)
• Application environment: production and repair workshops, industrial machining

How to use

Mount the tap in a suitable machine tapping holder or chuck that ensures concentricity and axial alignment. Drill the correct pilot hole to the recommended diameter for a 1/4" Whitworth internal thread before tapping. Use appropriate cutting speed, feed, and a compatible cutting fluid to reduce heat and aid chip removal. When tapping blind holes, retract periodically to break and clear chips; when tapping through holes, ensure the tap exits cleanly. Follow machine manufacturer guidelines for torque limits and tapping cycles to avoid tool breakage.

Usage recommendations

Use a suitable cutting lubricant and maintain correct spindle speed and feed for the material being machined. Inspect the pilot hole and tool alignment before each operation, and replace the tap if wear or damage is observed to maintain thread quality and dimensional accuracy.
