Product Specifications:
This HSSE-PM (Powder Metallurgy) spiral flute tap is manufactured using high‑speed steel powder metallurgy, which provides a uniform, fine‑grained carbide structure. Compared to conventional HSS or even standard HSSE, HSSE‑PM offers superior wear resistance, higher toughness, and consistent performance in high‑speed and interrupted cutting. The 15° spiral flute angle ensures efficient chip evacuation in blind holes, while the 3‑flute design delivers balanced cutting action and excellent thread finish.
Specifically for the M10x1.25 size, this tap is optimized for medium‑duty threading applications where precision and tool life are critical. With an overall length of 83mm and working length of 18mm, it is particularly well‑suited for automotive engine components, hydraulic valve bodies, and general machinery parts made of carbon steel, alloy steel, or stainless steel (up to 300 series). The compact geometry allows stable operation on both CNC lathes and manual tapping machines.
The uncoated surface provides a baseline for customers who prefer to apply their own specialized coatings. However, we also offer in‑house TiN, TiAlN, and CrN coatings upon request – each tailored to extend tool life in specific materials. For high‑volume production runs, the HSSE‑PM substrate has demonstrated up to 30% longer tool life compared to standard HSSE, reducing downtime and cost per hole.
Customization options for this M10 tap include left‑hand flutes, extra‑long shanks, and special thread tolerance classes (4H, 5H, 6H). OEM orders are welcome, with lead times as short as 15 working days for non‑standard configurations.
HSSE (cobalt-alloyed) and HSSE-PM (powder metallurgy) taps deliver enhanced threading precision, superior wear resistance, and high heat resistance – ideal for high-speed cutting in hard-to-machine materials. They are widely used in PCB supports, heatsinks, electronic enclosures, motor components, battery mounting holes, optical parts, and microthreads in miniature devices.
