- • Tolerance: ISO2 (6H)
- • Application: Blind-Hole Threading
HSS-E machine tap 35° spiral flute designed for efficient chip evacuation in blind-hole threading applications. The 35° helical flute geometry draws chips upward and out of the hole, preventing chip accumulation at the bottom of the thread. Ideal for CNC and manual machining of blind holes in steel, stainless steel, aluminum, and engineering alloys. Available in uncoated, TiN (Titanium Nitride), and TiCN (Titanium Carbonitride) coated options across Metric, Metric Fine, UNC, and UNF thread standards.

HSS-E Machine Taps - 35° Spiral Flute for Blind-Hole Threading
The 35° spiral flute machine tap, also known as a helical flute tap, is specifically engineered for threading blind holes where chip evacuation is critical. Its 35° helix angle lifts chips upward and out of the hole, preventing chip packing at the bottom and reducing the risk of tap breakage. This makes it the ideal choice for CNC machining centers, automotive component manufacturing, aerospace parts production, and general engineering applications involving blind-hole threads.
Our HSS-E spiral flute taps are manufactured from cobalt high-speed steel (cobalt 5%) with precision-ground 35° flute geometries optimized for different material groups. Uncoated taps provide a cost-effective solution for non-ferrous materials, aluminum alloys, and free-machining steels. TiN (Titanium Nitride) coated taps offer increased hardness and thermal stability for general-purpose steel threading. TiCN (Titanium Carbonitride) coated taps deliver superior wear resistance and reduced friction for high-alloy steels, stainless steels, and abrasive materials, significantly extending tool life in demanding production environments.
HSS-E 35° spiral flute machine taps are stocked in our Dubai warehouse and dispatched across the UAE, including to industrial and maintenance customers in Abu Dhabi, Sharjah, Al Ain and the Northern Emirates. Whether you need production spiral flute taps for a CNC cell in Musaffah or ICAD, or a hard-to-find size for an emergency repair, our team provides quotations, stock checks and fast delivery to Abu Dhabi and across the Emirates.
Available in Metric (M), Metric Fine (MF), UNC, and UNF thread standards. Contact our sales team for size availability, trade pricing, and stock information for Abu Dhabi and nationwide delivery.
