Ruko Thread Cutting Set M3–M12 (44-piece) – HSS workshop threading kit

Ruko Thread Cutting Set M3–M12 is a complete HSS threading kit for producing metric threads in unalloyed and low-alloy steels, malleable cast iron and non-ferrous metals in workshop and maintenance environments

• HSS cutting material for durability
• Covers metric threads M3 to M12
• Includes taps, dies and holders
• For unalloyed and low-alloy steels

Consistent thread quality through durable HSS cutting edges

The set is built around HSS cutting tools that retain hardness and edge stability in typical workshop conditions, resulting in repeatable, burr-free threads. The combination of high-speed steel and standardised geometries ensures clean chip formation and predictable cutting forces, which supports cycle-time reduction on manual and semi-automatic operations. For machining unalloyed steel and low-alloy steel up to 800 N/mm², the robust cutting material minimises wear and extends service intervals, translating directly into lower tooling costs over time.

Comprehensive kit design for flexible workshop applications

Supplied components include metric taps to DIN 352, round dies to DIN EN 22568, a set of die holders, adjustable die stocks and a thread gauge, together with core twist drills to DIN 338 Type N. This coordinated assortment permits both repair and production tasks without additional purchases. The presence of purpose-sized holders and an adjustable die stock means that threading can be set up quickly and held securely, reducing set-up errors and improving throughput for mixed batch work.

Practical handling reduces downtime and simplifies processes

Die holders in several widths and the adjustable stock sizes allow immediate adaptation to different rod diameters and clearance conditions, while the included core twist drill sizes match the tap diameters for precise pilot holes. The ergonomic die holders and the adjustable stock enable efficient manual threading in both through threads and blind holes, shortening process steps and lowering the risk of cross-threading. This pragmatic design supports workshop staff in maintaining a steady workflow with fewer interruptions.

Standards, compatibility and workshop benefits explained

Adherence to DIN 352 for taps and DIN EN 22568 for dies guarantees interchangeability with existing tooling and clarity when replacing individual items. The kit’s inclusion of a thread gauge and a screwdriver helps validate thread quality immediately at the bench, reducing rework. For operations that require machining malleable cast iron or non-ferrous metals, the diverse tool geometries included provide correct chip evacuation and surface finish, allowing both maintenance crews and small-scale production teams to rely on consistent results.
