TECWERK Machine Thread Tap DIN 376C M12x1.75 — HSS‑Co, TiN, ISO2 (6H)

The TECWERK Machine Thread Tap DIN 376C M12x1.75 is a right‑hand, TiN‑coated HSS‑Co tap designed for producing metric ISO blind threads to DIN 13 Blatt 1 with ISO2 (6H) tolerance.

• HSS‑Co construction with TiN coating
• Right‑hand 40° helix for chip control
• ISO metric thread to DIN 13, tolerance ISO2 (6H)
• Intended for blind‑hole tapping in steels ≤ 1000 N/mm²

Consistent threaded fit for interchangeable assemblies

Precision in thread form and tolerance reduces assembly issues and rework. The tap produces ISO metric threads in accordance with DIN 13 Blatt 1 and meets the ISO2 (6H) tolerance class, delivering an accurate internal thread suitable for standardised mating components. This level of precision ensures compatibility with common fasteners and thread gauges, which simplifies quality control and supports repeatable results in production runs.

Longer life and thermal stability for demanding jobs

Manufactured from HSS‑Co (cobalt alloy high‑speed steel) and finished with a TiN coating, the tool resists thermal softening and abrasive wear during prolonged cycles. The combination of substrate and coating extends service life and reduces the frequency of tool changes, contributing to shorter machine downtime and lower tooling costs per part. The tap’s 9 mm shank is suited to standard tool holders, providing secure clamping for stable machining.

Efficient chip evacuation and reliable blind‑hole performance

Designed with a 40° right‑hand helix and relieved flanks, the geometry promotes controlled chip formation and evacuation when cutting blind holes. Blind‑hole tapping presents the risk of chip congestion and incomplete threads; the tool’s helix and flank relief mitigate those risks by guiding chips away from the cutting edges and preventing clogging at the root of the thread. As a result, the machining process becomes more reliable and produces cleaner thread profiles with fewer tool interventions.

FAQ

What materials is this tap intended for?
The TECWERK machine tap is specified for use in steels with tensile strengths up to 1000 N/mm² and is designed to perform reliably under those conditions.

Is the tap suitable for blind‑hole tapping?
Yes, the geometry and helix angle of this tap are optimised for blind‑hole threads, reducing the likelihood of chip packing at the thread root.

What tolerance class does the tap produce?
This tap delivers threads to ISO2 (6H) tolerance in accordance with DIN 13 Blatt 1, providing standardised fits for mating fasteners.

How does the TiN coating benefit the tool?
The TiN coating increases surface hardness and reduces friction, which helps to extend tool life and improve wear resistance during repeated tapping operations.

What are the shank and mounting details?
The tool is supplied with a 9 mm shank, suitable for conventional tool holders used in machine tapping applications.
