FANAR tap UNC 1/2-13 DIN 376B (2B) HSSE TN 800X

FANAR tap UNC 1/2-13 DIN 376B (2B) HSSE TN 800X is a solid high-speed steel with cobalt (HSSE) cutting tool with a wear-resistant TN 800X coating. It is manufactured to the DIN 376B geometry and 2B tolerance for UNC 1/2-13 threads, intended for cutting or repairing external and through threads in materials suitable for HSSE tooling. The design supports both manual hand-tapping and machine tapping operations, providing consistent thread form and dimensional accuracy when used with appropriate speeds and lubricants.

Advantages

The HSSE material offers improved red-hardness and toughness compared with standard high-speed steel, enabling reliable performance in tougher materials and higher cutting temperatures. The TN 800X coating increases surface hardness and reduces friction, which helps extend tool life and improve chip evacuation during threading. DIN 376B geometry ensures thread form compliance and the 2B tolerance provides suitable fit for standard UNC fasteners. The tap’s construction makes it suitable for through-hole and external thread repair tasks as well as production environments.

Suitable for

• Cutting UNC 1/2-13 external and through threads in compatible metals
• Repair and maintenance of threaded components with UNC 1/2-13 threads
• Machine and manual tapping operations where DIN 376B (2B) tolerance is required
• Production runs requiring durable taps with enhanced wear resistance

Key specifications

• Thread form and size: UNC 1/2-13, DIN 376B geometry
• Tolerance: 2B (standard internal thread tolerance for UNC)
• Material: HSSE (high-speed steel with cobalt)
• Surface treatment: TN 800X wear-resistant coating
• Intended hole type: through holes and external thread repair
• Usage modes: manual and machine tapping

How to use

Select appropriate cutting speed, feed and lubrication for the workpiece material to optimize tool life and thread quality. For manual tapping, use a suitable tap wrench with stable alignment and apply steady pressure while turning to avoid cross-threading. For machine tapping, ensure correct spindle speed, alignment, and pecking or thread compensation cycles where applicable. Use cutting fluid compatible with the workpiece to assist chip evacuation and reduce heat. Inspect threads after tapping for correct form and fit with mating UNC fasteners.

Usage recommendations

Use the FANAR HSSE TN 800X tap in materials recommended for cobalt-alloy high-speed steel; avoid excessive speeds in non-recommended materials. Maintain proper lubrication and clear chips frequently. Replace taps at the first signs of wear or edge rounding to preserve thread quality and avoid damage to mating parts.
