TECWERK Hand finishing tap DIN 2181 No.2 — MF 12×1 HSS ISO2 (6H)

A TECWERK hand finishing tap designed for precise metric fine-thread cutting in workshop and industrial applications, suitable for through and blind holes.

• HSS construction for durable cutting edges
• MF 12×1 metric fine thread with ISO2 tolerance
• Suitable for through and blind hole tapping
• For steels up to ≈900 N/mm²

Consistent fine threads with proven materials and tolerance

The finishing cutter is made from HSS, which combines wear resistance with toughness to sustain repeated cutting cycles. The tool cuts a MF 12×1 metric fine thread to ISO2 (6H) tolerance, a standard that ensures reliable fit and interchangeability in assembly. The geometry specified by DIN 2181 as a No.2 finishing tap focuses on producing the final thread form with minimal material displacement, reducing the need for subsequent rework. The shank Ø 9 mm facilitates stable clamping in standard tap holders or chucks, supporting steady manual tapping performance.

Faster, safer tapping across common ferrous materials

Designed for right-hand cutting, this finishing tap is intended for both through and blind holes, improving cycle efficiency when used after an appropriate pilot drill. The tool is rated for steels with tensile strengths up to approximately 900 N/mm², making it suitable for many alloy and carbon steel applications encountered in maintenance, toolmaking and light production. Using a finishing tap with the correct tolerance reduces the likelihood of thread failure in assembly and can shorten inspection times—an outcome that supports smoother production workflows and lower overall processing costs.

Practical handling and application guidance for reliable results

The finishing tap’s configuration supports conventional hand-tapping workflows and simple machine tapping setups where manual control is required. Although optimised for finishing operations, correct pre-drilling and the use of suitable cutting fluid remain essential to extend tool life and maintain thread quality. The tool’s HSS material and finishing geometry help resist chipping and bluntness during normal use; periodic inspection of the cutting edges will indicate when replacement is necessary to sustain repeatable, high-quality threads.

FAQ

What thread form and size does this tap produce?
The tool produces a metric fine thread MF 12×1, finished to ISO2 (6H) tolerance for consistent fit and assembly.

Which materials is the tap suitable for?
The finishing tap is specified for use in steels with tensile strengths up to roughly 900 N/mm², making it appropriate for many alloy and carbon steel applications.

Is the tap suitable for blind holes as well as through holes?
Yes, the design covers both through and blind hole tapping when paired with the correct pilot drill and tapping procedure.

What does No.2 in DIN 2181 indicate?
No.2 denotes the finishing cutter geometry under DIN 2181, intended to create the final thread profile with minimal material deformation and high dimensional accuracy.

How should the tap be held and driven?
The shank Ø 9 mm enables clamping in common tap holders or chucks for stable manual or low-power machine tapping; correct alignment and controlled feed are essential for optimal results.
