Machine Tap DIN 376C VA M22×2.5 HSS‑Co – nitrided & vapour‑treated, 6H (TECWERK)

A Machine Tap DIN 376C VA M22×2.5 engineered for precision metric threading in blind holes and optimised for rust‑, acid‑ and heat‑resistant steels.

• HSS‑Co for enhanced wear resistance
• Nitrided and vapour‑treated surface
• ISO2 (6H) tolerance for precise thread fit
• Right‑hand helix 40° for blind hole threading

Durable material choice for heavy‑duty use

The combination of HSS‑Co (cobalt high‑speed steel) and thermal surface modifications ensures longevity where conventional taps wear quickly. The cobalt alloy raises hot hardness and resistance to abrasion, while nitrided and vapour‑treated finishing reduces surface friction and improves resistance to adhesive wear. These measures translate into fewer tap replacements and steadier cycle times when machining rust‑, acid‑ and heat‑resistant steels with tensile strengths > 850 N/mm², a common requirement in aerospace, energy and chemical industry components.

Thread accuracy that complies with standards

Designed to the metric specification DIN 13 Blatt 1, the threading geometry provides reliable engagement for assembly lines and maintenance operations. The ISO2 (6H) tolerance band delivers a close internal thread fit that reduces play and improves preloading of fastened joints. This level of precision supports predictable torque values and consistent mechanical performance across batches, which is crucial for production runs and quality control processes.

Geometry and treatment tailored for blind holes

The tool’s right‑hand helix 40° and flute design are optimised for evacuating chips in blind hole applications, minimising the risk of chip packing and breakage. Additionally, the cutting edges are flanks re‑ground, producing sharper, more stable cutting profiles that enhance surface finish and thread form. The blue ring marking provides quick visual identification in busy tooling cabinets, while the combined surface treatments lower friction to reduce tendency to galling on stainless and high‑strength alloys.

Practical integration and workshop advantages

With a shank Ø 18 mm, the tap integrates easily into standard machine tap holders and collets used in automatic tapping heads and CNC spindle adapters. The robust shank and treatment minimises downtime from tool changes and supports repeatable positioning. Supplied as a single unit, the tool is intended for workshops seeking dependable, long‑running performance with tools that match industrial standards. For specification matching and process optimisation, Metav Werkzeuge offers technical advice and product selection support to align the tool with production requirements.

FAQ

Is this tap suitable for stainless and heat‑resistant steels?
Yes. The Machine Tap DIN 376C VA M22×2.5 by TECWERK is specified for use in rust‑, acid‑ and heat‑resistant steels and for materials with tensile strengths > 850 N/mm².

What does the ISO2 (6H) tolerance mean for assembled parts?
The ISO2 (6H) tolerance of this tap ensures a close internal thread fit that reduces play between mating components, supporting predictable torque and preload in assemblies.

Can this tap be used for blind holes without additional coolant measures?
The right‑hand helix 40° and re‑ground flanks improve chip control in blind holes; however, appropriate lubrication or coolant is recommended depending on material and hole depth to optimise chip evacuation and tool life.

What size shank does the tap have and how does it fit into holders?
The tool features a shank Ø 18 mm, compatible with standard machine tap holders and many CNC collet systems for easy integration into production setups.

Are the threads formed to a recognised standard?
Yes, the tap produces metric threads in accordance with DIN 13 Blatt 1, providing standardised thread geometry for interchangeability and quality assurance.
