Machine tap set DIN 371/376 B M3–M12 – 14‑piece, HSS‑Co5 by RUKO

Machine tap set DIN 371/376 B M3–M12 is a professional threading solution for industrial and workshop applications, offering standard‑compliant taps and matching twist drills for reliable internal thread production

• HSS‑Co5 for high wear resistance
• Conforms to DIN 371/376 standards
• Complete M3–M12 metric tap range
• Includes matching twist drills

Faster production through standardised thread performance

This threading set delivers deterministic results in serial production thanks to its DIN 371/376 geometry and high‑grade HSS‑Co5 cutting material. The combination reduces thread rework and machine downtime by providing consistent chip formation and dimensional stability across batches. Where cycle time and repeatability matter, the tap geometry and material selection translate directly into fewer rejects and lower secondary operations, supporting measurable efficiency gains in production lines.

Durable material and predictable wear characteristics

Constructed from HSS‑Co5, the taps offer enhanced heat resistance and abrasion performance compared with standard high‑speed steels. The cobalt content improves red‑hardness, which is beneficial for higher cutting temperatures encountered in continuous machining. This material choice results in extended tool life and predictable maintenance intervals, allowing planners to estimate replacement cycles more reliably and to maintain throughput without unexpected tool failures.

Practical composition for workshop versatility

The set contains metric machine taps covering M3–M12, complemented by a matching range of twist drills (Ø 2.5 / 3.3 / 4.2 / 5.0 / 6.8 / 8.5 / 10.2 mm) to prepare accurate pilot holes. The inclusive assortment simplifies procurement and reduces set‑up time: a single kit supplies the common thread sizes used in component assembly and maintenance tasks. Labelling and organisation within the kit support quick selection and minimise tool changeover time on the machining centre or drill press.

Application guidance and material suitability

The tooling is optimised for general workshop and industrial use in a variety of metals; the HSS‑Co5 composition is particularly suitable where heat buildup is expected, for example in medium to high cutting speed operations. Correct drill‑to‑tap clearance and suitable lubrication are recommended to maximise the service life of the taps and to ensure clean chip evacuation. When used with appropriate feeds and coolant, the set produces accurate, burr‑reduced internal threads suitable for fastening and assembly tasks in production and repair environments.

FAQ

What sizes are covered by this tap set?
The RUKO machine tap set covers metric thread sizes M3–M12, providing common sizes for general industrial assembly and maintenance tasks; the kit includes the matching twist drills required for pilot holes (see twist drill list for exact diameters).

Is the material suitable for higher cutting speeds?
Yes, the taps are made from HSS‑Co5, which contains cobalt to improve heat resistance and is therefore better suited to higher cutting speeds than standard high‑speed steel taps.

Which standard do the taps conform to?
The taps conform to DIN 371/376, ensuring standardised thread form and interchangeability in industrial environments.

Does the set include pilot drills for each tap?
The set includes a selection of twist drills sized to match the taps commonly used in M3–M12 thread preparation, simplifying setup and ensuring correct drill‑to‑tap clearances.
