TECWERK Machine Thread Tap MF 18×1.5 mm — HSS‑Co, DIN 374C, 6H

TECWERK Machine Thread Tap MF 18×1.5 mm designed for metric fine threads to DIN 13; optimised for blind-hole threading and medium-to-high strength materials

• HSS‑Co for high cutting performance
• DIN 374C Form C geometry
• Right‑hand spiral 40° for blind holes

Faster, cleaner threading in blind holes

The HSS‑Co composition provides elevated red hardness and wear resistance, allowing efficient machining in tougher materials without rapid tool wear. The right‑hand spiral 40° evacuates chips toward the shank, which significantly reduces the risk of chip packing in blind holes and improves surface finish. Flanks that are precision-honed minimise burr formation and lower the need for secondary deburring—this translates into fewer rework steps and steadier cycle times on production lines that require fine metric threads.

Consistent assembly fit with DIN 13 and 6H tolerance

With its MF 18×1.5 mm thread form and 6H tolerance, the tool delivers a predictable internal thread geometry compatible with standard metric fine-thread fasteners. The designation to DIN 374C signals a standardised thread-cutting geometry, making the tap suitable where interchangeability and repeatable assembly play a role. For engineering teams specifying tolerance stacks, the 6H class balances manufacturing ease with reliable mating characteristics, helping to reduce rejected assemblies and ensuring consistent torque behaviour in bolted joints.

Robust shank and targeted material range for workshop use

A 14 mm shank diameter enables secure clamping in conventional collets and holders, supporting stable running and accurate pitch transfer from spindle to thread. The tool is designed for use in steels up to approximately 1000 N/mm² tensile strength, malleable cast iron, and long‑chip non‑ferrous metals, offering versatility across common industrial substrates. The Form C geometry and cobalt alloy combine to extend service life under intermittent production loads; when integrated into standard machining setups, the tool contributes to a predictable maintenance schedule and steady throughput.

FAQ

Which materials can be machined with this tap?
The TECWERK machine thread tap MF 18×1.5 mm is specified for steels up to approx. 1000 N/mm², malleable cast iron and long‑chip non‑ferrous metals, as stated in the technical data.

Is the tap suitable for blind-hole threading?
Yes; the right‑hand spiral at 40° is designed to evacuate chips from blind holes, making the tool appropriate for internal threads with limited depth.

What does the 6H tolerance mean for assembly?
The 6H tolerance class denotes the internal thread tolerance for metric ISO fine threads and ensures predictable fit with standard external threads, supporting reliable assembly performance.

How should the shank be clamped?
The tap has a 14 mm shank diameter and is intended for secure clamping in compatible collets or holders to maintain concentricity and minimise runout.

Which standard defines the thread form and geometry?
The thread form follows DIN 13 and the tool geometry is designated DIN 374C, providing standardised dimensions and cutting geometry for industrial applications.
