Maschinengewindebohrer DIN 376C M30×3.5 mm – HSS‑Co machine tap with right‑hand spiral, TECWERK

The Maschinengewindebohrer DIN 376C M30×3.5 mm is a machine tap designed for producing metric ISO threads in blind holes, combining cobalt‑alloy HSS for thermal durability with a 40° right‑hand spiral for controlled chip evacuation.

• HSS‑Co cobalt for high heat resistance
• Metric ISO thread M30×3.5 mm
• Right‑hand 40° spiral, Form C flanks
• Shank Ø 22 mm for secure clamping

Consistent, ISO‑grade thread precision for production use

The tool achieves M30×3.5 mm metric threads to DIN 13 sheet 1 standards with tolerance ISO2 (6H), delivering repeatable joint integrity for assemblies. Tight tolerance control reduces rework and minimises scrap by ensuring thread form and pitch match mating components; this is especially relevant where interchangeability and torque specifications matter. Specifying an ISO2 (6H) class provides a clear, industry‑recognised measure of fit quality, which supports downstream assembly processes and quality control documentation.

Engineered material and geometry for challenging steel work

Made from HSS‑Co (cobalt‑alloy high‑speed steel), the tap withstands the thermal and mechanical stress typical of machining medium‑high strength steels, specified for use in steels up to approximately 900 N/mm². The Form C geometry with flanks relieved and the right‑hand spiral 40° promote reliable chip formation and extraction when working blind holes, reducing the risk of chip packing. These design choices extend tool life and contribute to stable cycle times in serial production, supporting predictable throughput.

Secure clamping and machine compatibility for low runout

A shank Ø 22 mm offers a robust interface with standard taper adaptors or collet chucks, improving concentricity and reducing runout compared with smaller shanks. Improved clamping stability translates directly into cleaner thread flanks and reduced vibration, which in turn diminishes premature wear. The tool is intended for machine tapping operations; selecting appropriate holders and maintaining correct alignment will preserve the tap’s dimensional accuracy and surface finish.

Practical application and maintenance to preserve performance

The tap is optimised for blind hole tapping; the spiral lead and relieved flanks encourage chips to evacuate axially. For best results, apply suitable cutting fluid and monitored feed rates to balance chip control with cutting forces. Regular inspection of the thread profile and adherence to a replacement schedule will maintain process reliability. Supplied as a single unit, the tool integrates cleanly into production tool inventories and is suited to milling‑machine tapping heads and dedicated tapping centres where cycle repeatability is required.
