Take advantage of the reliable combination of HSS‑Co material, a vapourised surface finish and ISO2 (6H) tolerance to produce consistent, tight-fitting metric threads in mixed workshops; order directly via Metav Werkzeuge or consult our advisors for application support.

TECWERK machine tap M20 x 2.5 mm — HSS‑Co, Form B, 16 mm shank

The TECWERK machine tap M20 x 2.5 mm is a universal, straight‑flute tap designed for efficient production of metric ISO threads in steels and non‑ferrous materials.

• HSS‑Co construction with vapourised coating
• Straight flutes with flanks honed
• Metric ISO threads to DIN 13, ISO2 (6H)
• Cutting chamfer for reliable through threads
• 16 mm shank for secure machine mounting

Consistent, industry‑grade thread accuracy for production parts

The tap produces M20 x 2.5 mm metric threads with the industrial tolerance class ISO2 (6H) to DIN 13, Sheet 1, delivering predictable fits for assemblies that require repeatable precision. This tolerance class reduces post‑process adjustment or trial fitting and supports interchangeability in batch production. By specifying Form B, the geometry is tailored for machine use and standardised thread form, which benefits quality control and simplifies inspection routines.

Durable cutting performance for mixed materials and continuous cycles

Manufactured from HSS‑Co, the tool combines high‑temperature strength with toughness, making it suitable for demanding machining of steel, stainless steels, spheroidal cast iron and non‑ferrous metals. The vapourised surface finish improves wear resistance and reduces adhesion of workpiece material, extending service life under continuous operation. For workshops aiming to minimise tool changes, this material and coating pairing provides greater process stability and fewer interruptions during long runs.

Improved chip control and cleaner threads with reduced rework

The straight flutes and honed flanks deliver controlled chip formation and smooth cutting action, which is especially important when producing through threads with a dedicated cutting chamfer. The chamfer for through threads promotes chip evacuation and a clean thread start, lowering the risk of jamming and decreasing the need for subsequent deburring. Resulting thread quality means fewer rejected parts and a leaner workflow for mounting and assembly stages.

Machine compatibility and practical handling for workshop use

With a 16 mm shank and universal design, the tap fits standard machine holders and tool posts used in production lathes, machining centres and tapping heads. The universal specification supports flexible deployment across different machines without bespoke fixturing. For operations focused on throughput and consistent quality, the tool’s combination of robust shank, standardised thread geometry and durable cutting materials makes it a practical choice for everyday industrial tapping tasks.

FAQ

What tolerance does the tap produce and why does it matter?
The tap produces threads to ISO2 (6H) tolerance as specified to DIN 13, Sheet 1; this ensures consistent clearances and reliable interchangeability for mating parts when using the TECWERK machine tap M20 x 2.5 mm (SKU 2000867686NW).

Which materials are suitable for machining with this tap?
The tool is specified for steel, stainless steels, spheroidal cast iron and non‑ferrous metals, making the TECWERK machine tap appropriate for a wide range of workshop applications where mixed materials are processed.

What is the benefit of the vapourised coating on the tap?
The vapourised coating enhances surface hardness and reduces adhesion of workpiece material, improving wear resistance and extending the effective life of the tap in continuous production.

Does the shank fit standard machine holders?
Yes, the 16 mm shank is designed for secure mounting in common machine holders and tapping heads, allowing straightforward integration into existing machining setups.

How does the cutting chamfer affect thread quality?
The cutting chamfer for through threads facilitates chip evacuation and a clean thread start, minimising burrs and reducing the need for subsequent deburring or rework.
