Metric Fine Round Die MF20x1.5, HSS Form B – TECWERK

The Metric Fine Round Die MF20x1.5 is a Form B round die in high-speed steel, engineered for cutting ISO fine metric threads in medium-strength steels and workshop production settings.

• HSS cutting material for long life
• MF20x1.5 metric fine thread 6g
• Closed, pre-slit Form B design
• For steels up to 800 N/mm² strength
• Conforms to DIN EN 22568

Precision threading that reduces inspection and rework

The MF20x1.5 die is designed to produce repeatable, accurate metric fine threads with the 6g tolerance commonly required for standard external threads. Manufactured to DIN EN 22568, the tool’s geometry and the closed, pre-slit Form B profile ensure that the cutting edges maintain consistent tooth engagement across the full 14 mm height. This results in threads that meet dimensional expectations without excessive finishing, enabling smoother assembly and fewer rejects during serial production. The high-speed steel composition combines cutting performance with the ability to be reground, supporting long-term tool economy.

Reliable performance across typical workshop steels

Specified for use in steels up to approximately 800 N/mm², the die balances toughness and hardness to handle common structural and engineering materials. The closed pre-slit construction helps contain chips and promotes uniform chip evacuation, which in turn preserves thread flank quality and reduces the likelihood of seizing during interrupted cuts. In practice, this means shorter cycle times and more predictable throughput when producing fine-pitch metric threads for assemblies where fit and finish are important.

Built for durability, simple handling and consistent fit

The cutting material HSS offers wear resistance suited to workshop and light industrial environments while remaining serviceable for regrinding when required. The compact 14 mm height provides sufficient engagement to produce a full-profile thread, yet remains convenient to seat in standard round-die holders for hand or machine-driven applications. Because the die is specified for metric ISO fine threads and manufactured to recognised standards, it supports interchangeability and simplifies quality control during incoming inspection and assembly processes.

FAQ

What thread does this die cut?
The Metric Fine Round Die MF20x1.5 cuts MF20x1.5 metric fine threads with a 6g external tolerance (SKU 2000867771NW), suitable for standardised external thread fits.

Which materials is the die intended for?
This TECWERK HSS die is specified for use in steels up to approximately 800 N/mm²; it was developed for common engineering and structural steels within that strength range.

What are the benefits of the closed, pre-slit Form B design?
A closed, pre-slit Form B profile provides controlled chip formation and better alignment of the cutting edges, which helps to produce a clean flank geometry and reduce thread distortion.

Is this die suitable for repeated production runs?
Yes, the combination of HSS cutting material and standard-compliant geometry makes the die appropriate for workshop and small-series production where consistent thread quality is required.

How should the die be mounted for safe operation?
The round die engages over a 14 mm height and is intended to be used in a compatible round-die holder to ensure stable engagement and correct alignment during cutting.
