Sandvik 7/16-14 UNC Spiral Flute Tap – Premium Blind-Hole Tapping (DIN 2184-1)

Optimized for high-performance CNC and manual machining. The spiral flute geometry with a 45o helix ensures chips are lifted out of the hole, reducing clogging and protecting the thread form. Designed specifically for blind-hole applications in steels, stainless steels, and cast irons (PMK).

Key Features & Benefits

Extended Tool Life – Premium HSS-PM substrate with PVD FeN coating for durability and wear resistance.
Reliable Chip Evacuation – 45o spiral flute ensures clean cutting and swarf removal in blind holes.
Production Ready – DIN 2184-1 standard shank; 3-flute design provides balance between rigidity and chip space.
High Accuracy – Manufactured to UNC 2B tolerance for consistent, in-spec threads.
