Tap FANAR GWINTOWNIK M18x1,5 DIN-374B (6H) HSSE TN 800X — M18 x 1.5 metric tap, HSSE

FANAR GWINTOWNIK M18x1,5 DIN-374B (6H) HSSE TN 800X is a machine tap designed to produce internal metric threads M18 x 1.5 in metal components. Manufactured to the DIN 374B geometry with 6H tolerance class, this HSSE tool steel tap is intended for industrial machining and workshop environments where consistent thread quality and tool life are required. The tool's material and geometry allow for use at higher cutting speeds compared with standard high-speed steel taps while maintaining dimensional accuracy.

Advantages

The HSSE composition provides improved wear resistance and higher red hardness compared with conventional HSS, enabling longer life under demanding cutting conditions. DIN 374B geometry ensures reliable chip formation and evacuation for internal threading operations, reducing the risk of thread defects. The 6H tolerance class offers precise thread fit for components requiring standard metric tolerances. The tap's construction supports machine tapping, delivering repeatable results in series production and repair tasks.

Suitable for

• Cutting internal M18 x 1.5 metric threads in steel and other metals
• Machine tapping operations in lathes, milling machines and dedicated tapping machines
• Workshop repair and maintenance tasks requiring standard 6H tolerance threads
• Small- to medium-batch production where durability and consistent thread quality are needed

Key specifications

• Thread size: M18 x 1.5
• Thread form: Metric
• Standards compliance: DIN 374B geometry
• Tolerance class: 6H
• Material: HSSE (high-speed steel with cobalt)
• Application: Internal threading (machine tap)

How to use

Secure the workpiece and align the tap with the hole axis to ensure straight threading. Use an appropriate pilot hole diameter that matches the M18 x 1.5 thread specification. Operate the tap with a suitable machine feed or tapping head, applying cutting fluid compatible with HSSE tools to improve lubrication and chip evacuation. For blind holes, periodically retract the tap to clear chips; for through holes, ensure uninterrupted chip exit. Follow standard safety procedures and machine tool manufacturer recommendations for speeds and feeds.

Usage recommendations

For best results, select cutting speeds and feeds appropriate for HSSE taps and the workpiece material; use oil-based or synthetic cutting fluids for steel alloys. Inspect the tap for wear or damage before use and replace when thread quality degrades. When machining stainless steels or other difficult-to-cut alloys, reduce cutting speed and increase coolant flow to extend tool life.
