Product Specifications:
This HSSE straight flute tap with TiN coating is engineered for reliable threading in through holes and shallow blind holes. The 4‑flute design provides balanced cutting action and good chip evacuation, while the straight flute geometry offers maximum core strength, making it suitable for harder materials like alloy steel, stainless steel, and cast iron. The TiN (titanium nitride) coating reduces friction and improves wear resistance, extending tool life in general-purpose applications.
The M8x1.25 tap features an overall length of 80mm and a working length of 22mm, ideal for medium‑sized holes in automotive components, machinery parts, and structural steel. The HSSE substrate (cobalt‑alloyed) delivers higher heat resistance than standard HSS, allowing faster cutting speeds. For blind holes deeper than 2× diameter, consider a spiral flute tap; this straight flute version excels in through holes and short blind holes where chips can fall through.
Custom shank configurations and alternative coatings (TiAlN, AlCrN) are available for OEM orders. For cost‑effective, reliable threading in M8 size, this TiN‑coated straight flute tap delivers consistent quality and long tool life.
HSSE taps for mechanical manufacturing offer enhanced tool life, high heat resistance, and precision threading. Ideal for transmission parts, bearing housings, pumps, valves, and fasteners.
