RUKO Machine Tap DIN 371C M10 x 1.5 mm HSS 6H — Form C bottoming tap with 35° right-hand spiral

The RUKO Machine Tap DIN 371C M10 x 1.5 mm HSS 6H is a machine tap designed to cut metric ISO threads in blind holes, optimised for unalloyed and low-alloy steels, malleable cast iron and non‑ferrous metals in industrial machining environments

• HSS construction for durability and cutting stability
• Form C bottoming profile for full-depth blind-hole threading
• 35° right-hand spiral for effective chip evacuation
• 10 mm shank diameter for secure machine mounting

Reliable full-depth threads for blind-hole production

The Form C bottoming profile ensures threads are cut to the bottom of blind holes with consistent engagement and minimal taper, meeting DIN 13 specifications and the ISO2 (6H) tolerance band for interchangeability. By following the metric ISO thread standard, the tap guarantees compatibility with standard nuts and mating components, reducing rework and part rejection. The bottoming geometry is particularly useful where maximum thread length is required at the base of the bore, enabling secure fastening in assemblies where pull-out strength is critical.

Engineered chip control and material suitability

Built from high-speed steel (HSS) and equipped with a 35° right-hand spiral, the tool channels chips away from the cutting edge into the flutes, which is especially advantageous when working in blind holes. The cutting geometry is matched to a material range that includes unalloyed and low-alloy steels up to 800 N/mm² tensile strength, temper cast iron and a variety of non‑ferrous metals, delivering efficient chip formation and stable cutting performance. This combination reduces the risk of chip congestion and thread damage, improving process reliability under continuous production conditions.

Durable geometry and machine-ready shank

The tap features flank relief ground surfaces to reduce friction at the thread form and to improve finish quality while extending tool life. A 10 mm shank diameter provides a secure fit in collets or tool holders and supports accurate concentricity during high-speed spindle tapping. Designed for right-hand cutting, the tool is optimised for machine tapping cycles and automated tapping heads, enabling predictable feeds and consistent thread profiles across production runs.

FAQ

What materials can be machined with this tap?
The RUKO machine tap is suitable for unalloyed and low‑alloy steels up to 800 N/mm² tensile strength, temper cast iron and a range of non‑ferrous metals, as indicated in the product specification.

Is this tap appropriate for blind holes?
Yes — the Form C bottoming design and 35° right‑hand spiral are specifically intended for producing complete threads in blind‑hole applications.

What thread accuracy can be expected?
The tool produces metric ISO threads to DIN 13 with a tolerance band of ISO2 (6H), offering standardised fit and interchangeability for industrial assemblies.

Can the tap be used in automated machine tapping heads?
The 10 mm shank and machine‑oriented geometry make the tap suitable for use in collets and machine tapping heads where secure mounting and concentricity are required.

Does the RUKO tap have ground flank geometry and why does it matter?
Yes; the flanks are ground for relief, which lowers friction during cutting, improves surface finish and contributes to longer tool life under production conditions.
