Machine tap DIN 376C M18 x 2.5 HSS‑Co 6H TECWERK — high‑performance metric tap for blind holes

The Machine tap M18 x 2.5 HSS‑Co (DIN 376C) is intended for cutting metric ISO threads in blind holes and offers a balance of wear resistance and precision for medium‑to‑high strength steels

• HSS‑Co for elevated heat and wear resistance
• Right‑hand 40° spiral for blind hole chip control
• ISO2 (6H) tolerance for precise metric threads
• Shaft ø 14 mm for secure machine clamping

Consistent thread quality and extended tool life for production use

The combination of HSS‑Co construction and the DIN specifications provides a hard‑wearing cutting edge suitable for repetitive machining tasks. The tool is produced to DIN 376C and conforms with DIN 13 Blatt 1, delivering M18 × 2.5 metric threads to ISO2 (6H) tolerance; this reduces scrap rates and the need for repeat operations in serial production. Because the material grade is cobalt‑alloyed high‑speed steel, the tap maintains cutting geometry under elevated temperatures and abrasive conditions, which translates into longer in‑service life and fewer tool changes. The declared capability for steels up to approx. 900 N/mm² tensile strength makes the tool appropriate for many common structural and engineering alloys encountered on the shop floor.

Efficient chip control and secure machine mounting for reliable machining

A right‑hand 40° spiral is specified to assist chip formation and evacuation when producing threads in blind holes, preventing chip packing at the thread root and improving surface finish. The tool's flank honing (flanks hinterschliffen) reduces burr formation and facilitates smoother thread engagement, which is particularly beneficial when tapping materials that produce long, stringy chips. The shaft ø 14 mm supports secure clamping in standard tool holders and collets, ensuring concentricity and minimising run‑out; this contributes to repeatable thread geometry even under high spindle speeds. For users less familiar with tapping terminology, spiral angle and flank honing refer to chip‑directing geometry and a post‑grind smoothing of the cutting flanks intended to reduce initial cutting impact.

FAQ

Which materials can be machined with this tap?
The TECWERK machine tap is designed for machining steels up to approximately 900 N/mm² tensile strength; its HSS‑Co composition also copes well with a range of common engineering alloys.

Is the tap suitable for blind holes?
Yes — the spiral geometry and right‑hand 40° helix are optimised for blind hole applications to help evacuate chips and prevent thread damage.

What tolerance and thread standard does the tap meet?
Threads are produced to ISO2 (6H) tolerance and follow the metric specifications referenced in DIN 13 Blatt 1; the tool itself complies with DIN 376C.

What clamping diameter is required for the toolholder?
The shank requires a 14 mm clamping diameter for secure mounting in standard collets and tool holders.

How is surface quality influenced by the tool geometry?
The flank honing reduces burr formation and assists in achieving a consistent surface finish and fit, especially when cutting into materials prone to work hardening.
