RUKO Machine Tap M12×1.75 (DIN 376B) — HSS‑Co5, tolerance 6H

RUKO Machine Tap M12×1.75 for efficient, machine‑mounted production of metric ISO threads in steel, cast iron and non‑ferrous metals

*HSS-Co5 for improved wear resistance
*Straight-fluted form B for reliable chip guidance
*ISO metric thread M12×1.75, tolerance 6H
*Suitable for steels up to 1000 N/mm²

High wear resistance for long production runs

The HSS‑Co5 composition delivers higher red‑hardness and improved edge stability compared with standard high‑speed steel, which translates into extended tool life under elevated cutting temperatures. In practice this means fewer tool changes and steadier cycle times when producing metric threads into alloyed and unalloyed steels. The combination of HSS‑Co5 and a straight‑fluted geometry reduces flank wear and helps preserve thread form over long runs, making the tap a dependable choice for routine machine tapping tasks.

Precise threads with efficient chip control

Designed to DIN 376B and supplied to ISO2 (6H) tolerance, the tap ensures repeatable fits and interchangeability for assembled components. The straight‑fluted form B improves chip evacuation in through‑hole tapping and, together with the specified peel/shear cut for through threads, reduces torque peaks and the risk of chip jamming. As a machine tap with a 9 mm shank and right‑hand cutting direction, it integrates readily into standard collet spindles and tapping units to maintain process reliability and reduce setup time.

Versatile material capability and clear application benefits

Engineered for use in unalloyed and alloyed steels up to 1000 N/mm² tensile strength, temper cast and a range of non‑ferrous metals, this tool supports diverse workshop needs without frequent tool swaps. The relieved flanks (flank honing) promote a clean thread flank finish, while compliance with DIN 13 sheet 1 confirms adherence to recognised thread standards. The result is a balance of precision and robustness that supports consistent product quality in small batches and larger series alike.

FAQ

What materials can this tap machine process effectively?
The RUKO machine tap M12×1.75 is suitable for unalloyed and alloyed steels up to 1000 N/mm² tensile strength, temper cast iron and a range of non‑ferrous metals.

How does HSS‑Co5 benefit the tapping process?
HSS‑Co5 increases red‑hardness and wear resistance compared with standard HSS, helping the RUKO tap maintain cutting edge integrity and extend tool life under higher temperatures.

Is this tap intended for hand or machine use?
This tap is a machine tap to DIN 376B with a 9 mm shank, made for machine spindles and tapping units rather than manual hand‑tapping.

What chip control can be expected in through‑hole tapping?
The straight‑fluted form B and peel/shear cut are designed to facilitate chip evacuation in through holes, reducing torque spikes and lowering the risk of chip packing.

Does the tap comply with recognised thread standards?
Yes, the tool conforms to DIN 13 sheet 1 for metric threads and is produced to ISO2 (6H) tolerance for consistent fits.
