TECWERK Machine Tap DIN 374C MF 6×0.5 mm HSS‑Co, 6H tolerance

A TECWERK machine tap DIN 374C MF 6×0.5 mm engineered for blind holes and fine-pitch metric threads in demanding materials

• HSS‑Co alloy for extended tool life
• Form C geometry with 40° helix right-hand
• Suitable for blind holes
• Tolerance 6H for accurate fits
• Shank Ø 4.5 mm for stable clamping

Consistent thread quality for fine-pitch assemblies

The combination of HSS‑Co construction and a 6H tolerance provides a dependable basis for fine-pitch metric threads where repeatability matters. Cobalt-alloy high-speed steel increases red-hardness and wear resistance, extending tool life when machining steels up to approx. 1000 N/mm² or other long-chipping materials. Specifying a tap with an established tolerance class such as 6H reduces scrap rates and ensures compatible mating with standard ISO metric components, supporting tighter assembly tolerances and fewer reworks.

Geometry and chip control that suit blind-hole machining

Designed in Form C with a 40° helix and right-hand spiral, the tool promotes controlled chip formation and evacuation in blind holes. The helix angle and spiral direction help direct chips away from the cutting edge when space is limited, while relieved flanks (flank grinding) improve cutting action and reduce friction. Together, these design elements lower torque peaks during tapping and contribute to a cleaner thread root, which is particularly advantageous in confined or deep blind-hole threads.

Material compatibility and application benefits

This tap is specified for use in steels, temperguss (malleable cast iron) and long-chipping non-ferrous metals, making it suitable for precision components across mechanical engineering, instrumentation and small-series production. Because the tool tolerates higher tensile strengths (up to the stated limit), it is appropriate where medium to high-strength steels require fine-thread form and repeatable performance. The metric fine thread MF 6×0.5 mm conforms to DIN 13, providing industry-standard compatibility for mating parts.

Practical considerations for machine tapping and clamping

A shank Ø 4.5 mm allows stable clamping in standard collets or chuck adapters used on tapping heads and CNC tapping spindles. The tool’s right-hand spiral and ground flanks demand correct machine setup — secure clamping, appropriate withdrawal strategy and use of suitable cutting fluid where applicable — to get the most from the tap’s wear properties. For high-volume or critical threads, the tool’s geometry supports consistent cycle times while helping to avoid premature tool wear, thus improving overall process reliability.

FAQ

What materials can be machined with this tap?
The TECWERK machine tap MF 6×0.5 mm is specified for steels up to approx. 1000 N/mm², temperguss (malleable cast iron) and long-chipping non‑ferrous metals.

Is this tap suitable for blind-hole threading?
Yes, the tool is designed for blind holes; the Form C geometry and 40° helix support chip control in confined threads.

What tolerance and standard does the thread conform to?
The tap produces a metric fine thread per DIN 13 with tolerance 6H, providing standardised fit and interchangeability.

What is the shank diameter and how should it be clamped?
The shank diameter is 4.5 mm; stable clamping in an appropriate collet or tapping adapter is recommended to ensure concentricity and reduce deflection.

Can the tap be used on production machines or for hand tapping?
The design targets machine tapping; use in hand operations is possible but requires careful control of alignment and torque to avoid damage.
