M3x0.5mm Thread Tap ISO2 HSS-Co Form B Straight Flute Undercut 6H – TECWERK

High-precision M3 threads are achieved by combining HSS‑Co cutting steel with ISO2 (6H) tolerance and a Form B straight‑fluted geometry, delivering consistent thread quality and extended tool life for steels up to approximately 900 N/mm².

TECWERK single-cut tap, M3 x 0.5 mm — HSS‑Co, ISO2 (6H)

TECWERK single‑cut tap for producing metric M3 x 0.5 threads in medium‑strength steels and general workshop applications

• HSS‑Co cutting material
• Form B, straight‑fluted design
• M3 × 0.5 metric ISO thread
• ISO2 (6H) tolerance for precise fits

Precise threads with industrial tolerances for reliable assemblies

The straight‑fluted single‑cut tap is manufactured to DIN 352 and delivers a reliably controlled thread form thanks to the ISO2 (6H) tolerance band. This tighter tolerance ensures consistent screw fits and reduces assembly rework, an important efficiency factor in production environments. The cobalt‑alloyed HSS‑Co offers improved hot‑hardness compared with standard high‑speed steel, which helps maintain cutting geometry under elevated temperatures and in demanding series work.

Designed for through‑hole threading and clean chip evacuation

The tool features a Form B straight flute geometry combined with a special cutting lip for through‑hole threads, which promotes controlled chip formation and evacuation during tapping. The flank honing (flanked, honed edges) reduces burr formation and improves surface quality on the flank, meaning fewer downstream finishing steps. This design is particularly suitable where clean, repeatable threads are required in mechanical assemblies.

Material compatibility and workshop performance

Optimised for steels with tensile strength up to about 900 N/mm², the geometry and cutting material provide a balance between wear resistance and toughness. The tap is uncoated, avoiding potential coating flaking in interrupted cuts, while the cobalt content improves wear resistance over plain HSS. For routine maintenance and repair tasks in workshops or small‑batch production, the tool offers dependable tool life and predictable regrindability when required.

Practical benefits and integration into production

Specifying a tap with clear standards (DIN 352, ISO2) and a known material like HSS‑Co simplifies procurement and quality control processes. The straight flute and honed flanks reduce post‑threading cleaning and minimise the risk of thread damage during assembly, lowering rejection rates. For procurement managers and workshop supervisors, this results in fewer process interruptions and a more consistent end product.

FAQ

What materials is this tap suited for?
The TECWERK single‑cut tap is specified for use in steels up to approximately 900 N/mm² tensile strength and is uncoated to avoid coating issues in interrupted cuts.

Which standards and tolerances does this tap conform to?
This tap is manufactured to DIN 352 and produces threads to ISO2 (6H) tolerance for consistent metric fits.

Is the cutting material suitable for extended production runs?
Yes, the HSS‑Co construction provides enhanced hot‑hardness and wear resistance compared with plain HSS, making it suitable for many small‑ to medium‑batch operations.

How does the Form B geometry benefit through‑hole threading?
The straight‑fluted Form B design, combined with a cutting lip for through threads, promotes controlled chip formation and evacuation, reducing the risk of chip clogging and improving thread quality.
