Hand Tap FANAR 7/16" A1-220001-4230 — manual thread cutting tool

FANAR hand tap 7/16" A1-220001-4230 is a manual thread cutting tool designed for creating or repairing internal threads in metal and other machinable materials. The tool is intended for hand operation with a tap wrench and provides controlled, precise thread formation for workshop tasks, maintenance, prototyping and small-series production where machine tapping is not required.

Advantages

The hand tap is compact and simple to use, allowing accurate thread cutting without specialized machinery. Its geometry is suited for reliable chip removal and smooth cutting action when used at appropriate speeds and with correct lubrication. The tool supports consistent thread profiles, delivering acceptable repeatability for repair and small-batch manufacturing operations. Its manual nature reduces setup costs and enables work in locations without access to powered tapping equipment.

Suitable for

• Cutting or repairing internal threads in steel, brass, aluminum and other machinable metals
• Workshop maintenance and on-site repairs
• Prototyping and small-series production runs
• Use with a tap wrench for manual tapping operations

Key specifications

• Thread size: 7/16" (internal)
• Tool type: hand/plug tap for manual thread cutting
• Intended materials: steels, non-ferrous metals and other machinable materials
• Drive method: manual with tap wrench
• Typical applications: repair, maintenance, prototyping, small-series production

How to use

Secure the workpiece and center the hole to the correct pilot diameter before tapping. Use a suitable tap wrench to hold the hand tap vertically and apply steady forward pressure while turning clockwise to cut the thread. After several turns, reverse the tap about a half turn to break chips and clear the flutes, then continue cutting. Apply appropriate cutting fluid or lubricant for the material being worked to improve chip evacuation and extend tool life. Clean the tap flutes periodically during the operation and inspect the thread for correct form and depth when finished.

Usage recommendations

Choose the correct pilot hole diameter and use lubrication suited to the workpiece material. Maintain vertical alignment with the hole and clear chips frequently to prevent tool binding. For hardened or difficult-to-machine materials, consider pre-drilling with appropriate sizes and, if necessary, use a specialist or machine tapping method.
