TECWERK Machine Tap M20×2.5 HSS‑Co (Form C) – Universal, Vapour‑coated, 6H

A TECWERK Machine Tap M20×2.5 designed for producing ISO metric threads in blind holes across steel, stainless steel, spheroidal graphite cast iron and non‑ferrous metals

• HSS‑Co construction for high wear resistance
• Vapour‑coated surface with green ring identification
• Universal Form C for blind‑hole tapping
• ISO metric thread M20×2.5 with tolerance 6H

Faster, ISO‑accurate thread results for production use

The alloyed HSS‑Co substrate offers improved hot‑hardness and wear resistance compared with conventional high‑speed steels, which translates into longer tool life and more consistent cycle times. Combined with the ISO2 (6H) tolerance class and compliance with DIN 13 (sheet 1), this configuration delivers repeatable, inspection‑friendly threads that meet machine‑shop quality standards. Specified as a universal machine tap to DIN 376C, the tool supports standardised machining processes and simplifies tool inventory management in serial production environments.

Built to prevent chip jams and support blind‑hole tapping

Constructed as Form C with a right‑hand spiral at 40° and relief‑ground flanks, the geometry actively evacuates chips from the cutting zone and reduces the risk of thread damage when working blind. The spiral‑point and flank relief reduce thread build‑up and the tendency for chip packing, improving process reliability. These features make the tap especially suitable where secure chip removal is critical, such as interrupted cuts or deeper blind holes, enabling more stable cycle times and fewer rework operations.

Versatile material capability for workshop flexibility

The tool is specified for a broad range of materials: steel, stainless steel, spheroidal graphite cast iron and non‑ferrous metals, allowing the same thread maker to be deployed across mixed‑material production runs. The vapour‑coated surface increases wear resistance and can improve lubricity at the cutting edge, which is beneficial when machining harder stainless grades. By consolidating tapping operations with a single universal design, shops reduce tool changes and inventory complexity while maintaining thread quality across material types.

Machine compatibility and practical handling in daily use

With a shank diameter of 16 mm and a universal machine‑tap form, the item mounts easily in standard tapping spindles and tool holders used on turret and CNC machining centres. The green ring marking aids rapid visual identification on the tool board, shortening setup times. Supply in single‑unit packaging keeps stock control simple for precision maintenance spares. The combination of standardised shank size and universal geometry ensures the tool integrates smoothly into existing tapping cycles without special fixturing.

FAQ

What thread tolerance does this tap produce?
The TECWERK machine tap produces an ISO tolerance of 6H, conforming to DIN 13 (sheet 1) for metric threads, which is suitable for general engineering fits and repeatable inspection.

Is this tap suitable for blind‑hole threading?
Yes, the universal Form C geometry with a 40° right‑hand spiral is specifically designed to evacuate chips and reduce the risk of packing when creating blind holes.

Which materials can be machined with this tool?
The tap is specified for steel, stainless steel, spheroidal graphite cast iron and non‑ferrous metals, offering broad material flexibility for mixed production environments.

What is the shank size and how does it mount?
The tool has a 16 mm shank diameter, compatible with standard machine tap holders and spindles used in turret and CNC machines.

Does the vapour coating affect tool life?
The vapour‑coated finish enhances surface hardness and lubricity compared with uncoated tools, typically improving wear resistance and contributing to longer tool life in many applications.
