FANAR tap UNC No 6-32 DIN 352/3 (2B) HSS – thread cutting tool, No.6-32 UNC, high-speed steel

FANAR tap UNC No 6-32 DIN 352/3 (2B) HSS is a thread cutting tool designed to produce internal Unified National Coarse (UNC) No.6-32 threads. Manufactured from high-speed steel and produced to DIN 352/3 geometry, this tap is intended for hand or machine use and provides threads to a 2B tolerance class. It is suitable for cutting or restoring internal coarse threads in materials compatible with HSS tooling and is used in general engineering, maintenance and assembly operations.

Advantages

The HSS construction offers good wear resistance and toughness for a broad range of common engineering materials. Conformance to DIN 352/3 geometry ensures consistent flute form and chip evacuation characteristics suitable for UNC thread profiles. The tap is manufactured to produce 2B tolerance internal threads, providing reliable fit with standard UNC external fasteners. Its design allows use in both manual tapping and machine tapping applications where appropriate tapping speeds and lubrication are applied.

Suitable for

• Creating No.6-32 UNC internal threads in metals and compatible alloys
• Repairing damaged or worn UNC threads during maintenance
• Assembly tasks requiring standardized 2B tolerance internal threads
• General workshop and engineering applications with hand or machine tapping

Key specifications

• Thread form: Unified National Coarse (UNC)
• Thread size: No.6-32
• Tolerance class: 2B (internal)
• Material: high-speed steel (HSS)
• Geometry standard: DIN 352/3
• Intended use: hand or machine tapping

How to use

Select an appropriate drill size for the No.6-32 UNC tap and prepare the hole with correct alignment. Secure the workpiece and use suitable cutting fluid for the material being tapped. For hand tapping, start the tap square to the workpiece and turn clockwise to cut, periodically reversing a fraction of a turn to break chips and aid evacuation. For machine tapping, use appropriate spindle speeds and feed to match the tap and material; ensure proper clamping and automatic chip clearance if available. After threading, remove swarf and inspect the thread for correct fit with a mating fastener.

Usage recommendations

Use cutting fluid appropriate to the workpiece material, maintain correct alignment to avoid thread distortion, and replace the tap if wear or chipping occurs to preserve thread quality and dimensional accuracy.
