Tap FANAR GWINTOWNIK M16x1.5 NGMM/2-P DIN-2181 (6HX) HSSE INOX

Tap FANAR GWINTOWNIK M16x1.5 NGMM/2-P DIN-2181 (6HX) HSSE INOX is a machine tap engineered for cutting standard metric threads M16 x 1.5. The tool is manufactured in solid HSSE INOX material and follows DIN‑2181 geometry with 6HX tolerance, providing consistent thread form for both through and blind holes. It is intended for use in production and repair settings with tapping machines or CNC equipment where stainless and alloy steels require improved wear resistance.

Advantages

The HSSE INOX construction increases hardness and wear resistance compared with conventional high-speed steels, extending tool life when machining stainless and alloy steels. DIN‑2181 geometry ensures controlled chip formation and stable thread profile, while 6HX tolerance offers slightly generous clearance to facilitate assembly and compensate for minor alignment or size variations. The tap's design suits both machine tapping and CNC operations, enabling repeatable thread quality in batch production.

Suitable for

• Cutting M16 x 1.5 metric threads in stainless steel
• Tapping alloy steels with increased wear resistance requirements
• Machine tapping and CNC tapping operations
• Through holes and blind hole thread production
• Maintenance and repair work in industrial environments

Key specifications

• Thread size: M16 x 1.5
• Geometry standard: DIN‑2181
• Tolerance class: 6HX
• Material: HSSE INOX (high-speed steel with cobalt, corrosion-resistant grade)
• Application: machine tap for production and repair
• Suitable hole types: through holes and blind holes

How to use

Secure the workpiece and select the recommended pilot drill size for M16 x 1.5 threads. Mount the FANAR M16x1.5 NGMM/2-P tap in a suitable tapping holder or machine spindle. Use appropriate cutting speed and feed for HSSE INOX when machining stainless or alloy steels, and apply cutting fluid or coolant compatible with stainless materials to assist chip evacuation and reduce heat. For blind holes, reverse the tap periodically to break chips and avoid chip packing. Inspect thread fit and finish after tapping and deburr edges as needed.

Usage recommendations

For best results, match drilling and tapping parameters to the workpiece material: use reduced cutting speeds and steady lubricant flow for stainless steels, and avoid excessive feed rates that can overload the tap. Replace the tap when wear or chipping affects thread quality to maintain consistent assembly tolerances.
