20mm Hand Tap MF20x1.5 HSS ISO2 (6H) For Through And Blind Holes, Metric Fine Thread DIN 2181 - TECWERK

Take advantage of a hardened HSS construction combined with an ISO2 (6H) tolerance to produce consistent, serviceable fine threads; order directly via Metav Werkzeuge or consult our technical advisors for application-specific guidance.

Hand Tap DIN 2181, Finish Tap No. 2 – M20 x 1.5 HSS, ISO2 (6H) | TECWERK

A Hand Tap DIN 2181 engineered for metric fine threads, suitable for through and blind holes and steels up to approximately 900 N/mm².

• HSS construction for durability
• ISO fine thread M20 × 1.5, tolerance ISO2
• Suitable for through and blind holes
• Compatible with steels up to 900 N/mm²
• 16 mm shank for secure clamping

Consistent fine threads with industrial tolerances

The finish tap is designed to produce M20 x 1.5 metric fine threads to the DIN 13 specification, delivering the dimensional reliability required in production and repair work. The ISO2 (6H) tolerance class ensures that internal threads meet common assembly requirements for medium-fit applications; this reduces rework and minimises rejected parts. Where traceable, repeatable thread form is essential, the combination of finish geometry and standard-compliant tolerance gives a deterministic outcome that supports downstream assembly processes.

Robust material and cutting behaviour for demanding steels

Manufactured from HSS, the tool offers a balance between toughness and wear resistance suited to conventional workshop environments. The geometry is right-hand cutting and intended for both through and blind holes, enabling versatile use across component types. The tool is rated for steels up to about 900 N/mm² tensile strength, which covers many structural and engineering grades; this capability reduces the number of specialised taps needed in a mixed-material shop and streamlines tool inventory.

Workshop-ready design that speeds set-up and handling

A 16 mm shank diameter provides a secure interface with standard chucks and tap holders, improving concentricity and reducing run-out during manual or powered tapping operations. The designation as a finish tap (Fertigschneider) indicates a geometry optimised for producing the final thread form after any initial sizing or intermediate passes; this shortens total cycle time by reducing the need for corrective passes. Clear labelling and standard dimensions also simplify tool selection and inventory management, helping maintain a steady production flow.

FAQ

What materials can be machined with this tap?
The TECWERK hand tap (SKU 2000867089NW) is made from HSS and specified for use on steels up to approximately 900 N/mm², making it suitable for many common engineering steels.

Is this tool suitable for blind holes?
Yes. The design supports both through and blind holes, and the finish geometry is intended to complete the thread form in the final pass.

What does the tolerance ISO2 (6H) mean for assembly?
The ISO2 (6H) tolerance provides a standard medium-fit internal thread suitable for reliable assembly without excessive play; the TECWERK finish tap produces threads that comply with this class for predictable mating behaviour.

Can the tap be used in a powered tapping holder?
The 16 mm shank allows secure mounting in standard holders and chucks; however, matching the holder to the machining method and ensuring correct alignment are essential for best results with this finishing tap.
