M14 INOX machine tap – in accordance with ISO 529
The Narex M14 INOX machine tap is designed for precision tapping of 14 mm diameter holes in stainless and structural steels. Its HSSE high-speed steel construction with 5% cobalt guarantees a hardness of 66 HRC and long cutting edge life even when machining difficult-to-machine materials. Form C with straight flutes provides versatility for through and blind holes. The 6H tolerance in accordance with ISO 529 confirms manufacturing quality to international standards. The M14 HSSE machine tap is intended for series production departments and industrial service shops.
Key features of the Narex M14 INOX tap
- Manufacturing precision to 6H tolerance ensures dimensional repeatability and full thread interchangeability in series production of mechanical and hydraulic components
- Compliance with ISO 529 ensures internationally standardized dimensions and interchangeability with tools from global manufacturers in Europe and Asia
- Durability increased by the addition of 5% cobalt allows operation at temperatures up to 650°C without loss of cutting edge performance
- Material versatility covering austenitic stainless steels, structural steels up to 800 MPa, gray and ductile cast iron, and aluminum alloys
- Compatibility with ER25 holders and tapping heads for CNC machining centers with synchronous tapping and automatic tool changing
- Universal M14 machine tap with form C allows through and blind holes to be tapped with a single tool without the risk of jamming
The Narex M14 machine tap for through and blind holes is used in steel structures and industrial welding applications requiring durable threaded joints. European manufacturing quality guarantees long tool life and repeatability. The tap drill diameter for the M14 thread is 12 mm.

Frequently asked questions
The M14 HSSE tap with form C and straight flutes is universal – suitable for both through holes and blind holes. Its design ensures proper chip evacuation in both hole types.
The M14 HSSE tap produces an internal thread to tolerance class 6H. The designation 6H specifies the permissible deviations of the thread pitch and minor diameters – the digit 6 indicates the tolerance zone width (medium), and the letter H indicates the position of the zone at the zero line. Tolerance 6H ensures proper fit with screws to tolerance 6g.
When tapping stainless steels, an EP emulsion at a minimum concentration of 8% or tapping oil is recommended for cooling. Cooling extends tool life by a factor of 2-3 and improves the thread surface finish.
