Machine Tap FANAR 3/8" model D2-121101-3129, right-hand threading

FANAR machine tap 3/8" model D2-121101-3129, right-hand threading is a precision cutting tool engineered to produce internal 3/8" threads in metal workpieces. Designed for use in machining centers and dedicated tapping machines, this tap is suitable for general repair, maintenance and production tasks where accurate thread form and repeatability are required. The tool is applicable to both through and blind holes when used with appropriate machine setup and process parameters.

Advantages

This FANAR machine tap delivers consistent thread geometry and dimensional stability, reducing the need for secondary fitting operations. Its right-hand threading and geometry are optimized for machine tapping cycles, which helps maintain feed and speed consistency. The tool is manufactured to tight tolerances, providing reliable performance in repetitive production and repair environments while minimizing tool changeovers and setup time.

Suitable for

• Creating internal 3/8" threads in steel and non-ferrous metal components
• Tapping operations in machining centers and automated tapping machines
• Repair and maintenance tasks requiring accurate thread restoration
• Production runs where repeatable thread quality is needed

Key specifications

• Thread size: 3/8" (internal thread)
• Hand: right-hand threading
• Tool type: machine tap for use in machining centers and tapping machines
• Suitable hole types: through holes and blind holes (depending on setup)
• Application materials: metals including steels and common non-ferrous alloys

How to use

Secure the workpiece and install the tap in the machine spindle or tapping head according to the equipment manufacturer's instructions. Select appropriate spindle speed, feed rate and cutting fluid for the workpiece material and hole depth. For blind holes, monitor plunging depth to avoid bottoming; for through holes, ensure adequate chip evacuation. Use peck tapping or chip-breaking cycles where necessary to prevent chip jamming and improve surface finish. After tapping, inspect thread form and dimensions with gauges or appropriate measuring tools.

Usage recommendations

Use cutting fluid suitable for the workpiece material, maintain recommended speeds and feeds for machine tapping, and replace the tap when wear or chipping affects thread quality. For automated tapping, confirm spindle runout and alignment to preserve tool life and maintain consistent thread dimensions.
