Machine Tap FANAR G3/8" - model D2-511101-3129, thread G3/8"

FANAR machine tap G3/8" (model D2-511101-3129) is a precision cutting tool designed to produce internal G3/8" threads in pre-drilled holes. Manufactured for use on machining centers and lathes, this tap delivers consistent thread geometry for metalworking and assembly operations. The tool is intended for industrial and workshop environments requiring standard G3/8" internal threads and is compatible with typical machine tap holders and fixtures.

Advantages

The FANAR machine tap provides accurate thread forming and cutting due to its precise flute geometry and cutting edges, ensuring repeatable results across multiple pieces. It is engineered for machine use, offering reliable concentricity when used in rigid tapping setups or tapping heads. The tap reduces setup time by delivering uniform thread quality and helps maintain process stability in batch production and single-part machining tasks.

Suitable for

• Producing G3/8" internal threads in metal components
• Use on CNC machining centers and manual lathes with machine tapping capability
• Workshop repair and maintenance tasks requiring standard pipe or fitting threads
• Batch production where consistent internal thread dimensions are required

Key specifications

• Thread size: G3/8" (BSPP standard internal thread)
• Tool type: machine tap for internal thread cutting
• Intended mounting: machine tap holder or lathe tailstock tapping setup
• Application material: suitable for common workshop metals (e.g., steel, stainless steel, aluminium) depending on machining parameters
• Use case: for producing standard internal threads in drilled or bored holes

How to use

Secure the workpiece and verify that the hole diameter matches the recommended drill size for a G3/8" internal thread. Mount the FANAR machine tap in a suitable machine holder or tapping head, ensuring proper alignment and rigid support. Use appropriate cutting fluid for the workpiece material, set the machine to the correct spindle speed and feed for machine tapping, and perform the tapping cycle following the machine's tapping procedure. Retract carefully after cutting to avoid thread damage and inspect threads for proper engagement and dimensional conformity.

Usage recommendations

Use lubricants appropriate for the work material, monitor spindle load during tapping, and use rigid tapping or a floating tapping head where possible to improve concentricity and thread quality. Confirm hole preparation and drill size before tapping to ensure correct thread form for G3/8" fittings.
