TECWERK machine tap MF22×1.5 HSS‑Co — DIN 374C, right‑hand 40° spiral

A TECWERK machine tap MF22×1.5 HSS‑Co designed for machining metric fine threads in blind holes in steels up to approx. 1000 N/mm², malleable cast iron and long‑chipping non‑ferrous metals

• HSS‑Co construction for high wear resistance
• Right‑hand 40° spiral for blind holes
• DIN 374C, metric fine thread MF 22×1.5
• Shank Ø 18 mm for secure clamping

Accurate fine threads with proven DIN specification

The tool is manufactured to DIN 374C and produces a metric fine thread (MF 22×1.5) with a 6H tolerance that ensures consistent fit and interchangeability. Such standard conformity means threads are comparable across assemblies and replacement parts, reducing rework and inspection time. The cobalt alloy in HSS‑Co increases red hardness and wear resistance, so thread form is retained over longer production runs, which contributes to predictable cycle times and lower tool change frequency.

Reliable blind‑hole tapping thanks to spiral geometry

Equipped with a right‑hand 40° spiral, the tap actively evacuates chips from the cutting zone when used in blind holes; this significantly reduces chip jamming and the risk of thread damage. The flanks are relief‑ground, improving chip control and leaving clean flank surfaces on the thread form. For applications where chip evacuation and surface integrity are essential, this spiral‑flute design is particularly effective, and the tool is optimised for blind‑hole use rather than through threading.

Robust shank and compatibility with common workshop setups

A shank Ø 18 mm provides a stable connection to standard toolholders and reduces vibration during tapping. The combination of shank diameter and the DIN specification allows secure clamping in end‑mill holders or collet chucks commonly used in production cells. The cutting geometry and material specification make the tap suitable for operation in steels up to approx. 1000 N/mm², tempered cast iron and many long‑chipping non‑ferrous alloys, balancing cutting performance with tool life in mixed‑material job shops.

Practical benefits for production and maintenance planning

Using a cobalt high‑speed steel tap with defined spiral and relief features reduces the incidence of broken taps and rework, improving first‑pass yield. The tool’s construction supports higher temperatures at the cutting edge, allowing slightly more aggressive feeds in many cases without sacrificing thread quality. For buyers and production planners this translates into fewer tool changes, less downtime and a demonstrable impact on throughput.

FAQ

What thread does this tap produce and to which standard does it conform?
The tap produces a metric fine thread M22×1.5 and is manufactured to DIN 374C, ensuring the thread form and tolerance class 6H meet standardised requirements.

Which materials can be machined with this tool?
This TECWERK machine tap MF22×1.5 HSS‑Co is specified for steels up to approx. 1000 N/mm², malleable cast iron and long‑chipping non‑ferrous metals; the cobalt alloy improves performance in tougher materials.

Is this tap suitable for blind holes or through holes?
The spiral‑flute design with a 40° right‑hand spiral is optimised for blind‑hole applications, as chip evacuation is directed away from the cutting edge to reduce packing.

What clamping arrangements are recommended for stable operation?
The shank Ø 18 mm is intended for secure clamping in collets or holder systems common in production environments to minimise runout and vibration.

How does the HSS‑Co material affect tool life and cutting parameters?
Cobalt alloyed HSS retains hardness at elevated temperatures, allowing more aggressive cutting in many cases and extending tool life compared with standard HSS for comparable operations.
