21pc HSS Hand Tap Set Metric ISO M3–M12 DIN 352 For Through and Blind Holes - Ruko GmbH

A compact, standards‑compliant kit that pairs HSS durability with DIN 352 geometry to deliver reliable metric threading from M3–M12; the 21‑piece layout supports both through and blind holes and is available via Metav Werkzeuge for straightforward procurement and technical guidance.

Ruko Hand tap set DIN 352 M3–M12 — 21‑piece HSS taps

A Ruko Hand tap set DIN 352 M3–M12 engineered for manual metric threading in common workshop materials including steels, cast irons and non‑ferrous metals.

• High-performance HSS taps
• DIN 352 standard geometry
• Metric ISO threads M3–M12
• For through and blind holes

Reliable threads with production‑grade geometry

The set is built around HSS cutting material and the DIN 352 profile to ensure consistent thread form and long tool life under manual use. This combination reduces the likelihood of thread distortion and wear, which translates into fewer scrapped components and less rework. The standardised geometry also simplifies quality assurance: thread gauges and M‑class fittings mate predictably, making integration into existing inspection routines straightforward.

Suitable for common engineering materials and moderate tensile strengths

Designed for applications in unalloyed and low‑alloy steels up to 800 N/mm², the taps also machine temper cast iron and a range of non‑ferrous metals without specialised tooling. Specifying the allowable tensile strength provides an objective basis for tool selection: users can assess whether the kit fits their workpiece material rather than relying on vague claims. The result is a measurable reduction in trial‑and‑error and a clearer route to dependable production outcomes.

Practical layout for manual tapping operations

The 21‑piece composition covers the standard metric progression from M3–M12, permitting one‑stop access to everyday thread sizes. Organisation in a compact set accelerates size selection and reduces setup time at the bench. For through and blind holes, the tool geometry and flute design support efficient chip evacuation when combined with appropriate lubrication; this preserves cutting edges and maintains surface finish. Basic procedural advice—correct alignment, steady feed and suitable cutting fluid—will extend service life and improve repeatability.
