M12x1.75mm Single-Entry Tap HSS-Co Form B Straight Flute Metric ISO2 (6H), Through-Hole Cutting - TECWERK

Take advantage of the robust cutting geometry and cobalt-enhanced HSS to achieve consistent M12 x 1.75 threading with minimal rework; order through Metav Werkzeuge or consult its workshop specialists for application advice.

Single-cut tap DIN 352 Form B M12 x 1.75 HSS‑Co ISO2 (6H) — TECWERK

A single‑cut metric tap designed for producing accurate through‑threads in medium‑strength steels in workshop and production environments.

• Cobalt high-speed steel (HSS-Co) for wear resistance
• Straight flute Form B for stable chip control
• Relief-ground flanks for smooth thread entry
• Chamfered lead for reliable through-threading

Greater process reliability through hardened cutting geometry

This TECWERK single‑cut tap is manufactured from HSS‑Co, combining toughness with wear resistance to extend life in serial tapping operations. The Form B design and straight-flute geometry deliver controlled chip formation, which reduces the risk of chip jamming and subsequent thread damage. For production environments that value repeatable quality, the result is fewer rejected parts and less downtime, as the tool’s geometry supports consistent thread profiles and dimensional stability.

Smooth engagement and reduced thread rework

The tap’s relief-ground flanks and chamfered lead are engineered to ensure gradual tool engagement and reliable centring when cutting metric ISO threads. These features reduce insertion torque and minimise wobble during hand or machine tapping, which translates into smoother machining cycles and a lower rate of thread correction. When working with medium-strength steels, the combination of cutting material and flank relief helps maintain thread form and surface finish, so post‑machining processes are shortened.

Standards and compatibility explained for easier selection

Supplied for M12 x 1.75 mm metric threads to DIN 13 (sheet 1) with tolerance class ISO2 (6H), this tool fits standardised tapping workflows and inspection routines. “Single‑cut” indicates a single fluted profile optimised for through‑holes and straightforward chip evacuation; the tool is uncoated, making it suitable for general steel applications and for users who prefer regrinding and maintenance rather than sacrificial coatings. For steels up to approximately 900 N/mm² tensile strength the tool offers an effective balance between hardness and toughness.

Practical workshop advice and application scenarios

In a busy workshop, this tap excels when used in dedicated tapping holders or machine spindles where alignment is controlled; the straight flute and chamfer work particularly well for blind‑reamed or through‑drilled holes prepared to standard hole sizes for M12 threads. The tool’s HSS‑Co composition supports intermittent cutting and higher thermal loads compared with standard HSS, making it a pragmatic choice for small batch production and maintenance tasks where durability matters. For optimal service life, pair the tap with appropriate coolant and moderate feed rates that match the workpiece material and machine rigidity.

FAQ

What materials is this tap suitable for?
The Single-cut tap DIN 352 Form B M12 x 1.75 HSS‑Co ISO2 (6H) TECWERK is intended primarily for steels and is rated for workpieces up to around 900 N/mm² tensile strength.

Is the tool suitable for through‑threads or blind holes?
The chamfered lead and straight-flute design make the TECWERK single‑cut tap particularly suited to reliable through‑threading; it can be used in blind holes if chip evacuation is ensured.

What tolerance and standard does the tap conform to?
This tapping tool conforms to DIN 13 (sheet 1) and produces threads to tolerance class ISO2 (6H), appropriate for standard metric assembly requirements.

Does the tap have a coating for improved wear resistance?
The tool is supplied uncoated; longevity is achieved through the HSS‑Co cutting material and the controlled geometry rather than a surface coating.

Can the tap be used in handheld tapping wrenches or only in machines?
The geometry supports both machine and controlled hand tapping; however, for consistent results and reduced breakage risk, machine tapping with rigid alignment or tapping holders is recommended.
