TECWERK machine tap — M3 x 0.5 mm HSS‑Co, straight flute, 6H tolerance

A TECWERK machine tap designed for precision internal threads in demanding materials; suitable for machine tapping of metric ISO threads where consistent tolerance and heat resistance are required

• HSS‑Co for high temperature strength
• Straight flute for reliable chip evacuation
• ISO2 tolerance field (6H) ensures accurate threads
• Peel chamfer for through-hole tapping

Extended performance through material and tolerance design

The combination of HSS‑Co (cobalt‑alloyed high‑speed steel) and a strict ISO2 (6H) tolerance field provides tangible production advantages: enhanced heat resistance extends tool life under elevated cutting temperatures, while the 6H tolerance supports reproducible, serviceable internal threads that meet DIN reference standards. For workshop planners and production engineers, this means fewer rejects and less rework when producing metric fastenings to specification. The material choice is particularly beneficial when machining tougher alloys where standard high‑speed steels would wear prematurely.

Improved chip control and thread finishing for reliable throughput

A straight flute geometry combined with flanks that are relief ground (flank honing) reduces the risk of chip congestion in through‑hole operations. The integrated peel chamfer is engineered to initiate a controlled cut for through threads, reducing axial force peaks and improving thread profile integrity. These features translate into smoother machining cycles and a lower likelihood of tap breakage during continuous or automated tapping processes. Clear chip evacuation and a consistent cutting entry also simplify downstream quality assurance by yielding cleaner thread forms.

Integration into production and practical handling

Designed in accordance with DIN 13 specifications and produced as Form B / Type H, this tap fits established machine tap holders; the shaft 3.5 mm dimension supports secure clamping and stable torque transmission for machine tapping applications. The tool’s marking (red ring) assists fast identification on tool trolleys and in automated tool systems, aiding workflow efficiency. For procurement and operations teams, the result is a compact, robust solution that meshes with existing tool inventories while addressing the specific challenge of machining hard steels above 1000 N/mm² tensile strength.

FAQ

What materials can be machined with this machine tap? This TECWERK machine tap is manufactured from HSS‑Co and specified for machining hard steels including applications with tensile strengths over 1000 N/mm².

What does the tolerance field ISO2 (6H) mean for production? The ISO2 (6H) tolerance indicates a tighter internal thread tolerance class, ensuring consistent fit and interchangeability of threaded parts produced with this tap.

Is the tap suitable for through or blind holes? The integrated peel chamfer is designed for through‑hole tapping and promotes controlled chip formation and ejection in through operations.

Which standard does the thread conform to? Threads produced with this tool conform to the metric guidance of DIN 13 and are formed as per the declared thread size M3 x 0.5 mm.

How is chip evacuation supported by the tool design? Chip evacuation is aided by the straight flute geometry and honed flanks, which together reduce chip packing and allow a steadier machining process.
