Sandvik #10-24 UNC Spiral Flute Tap – Premium Blind-Hole Tapping (DIN 2184-1)

Engineered for high-performance CNC and conventional machining. The spiral flute geometry (45o helix) lifts chips up and out toward the entry side, protecting the thread form and preventing chip packing in blind cavities. Ideal for blind holes in steels, stainless, and cast irons (PMK).

Key Features & Benefits

Extended Tool Life – HSS-PM substrate with PVD FeN coating resists wear and built-up edge.
Superior Chip Evacuation – 45o spiral flute pulls swarf out of blind holes for reliable tapping.
Production Ready – DIN 2184-1 shank; 3-flute design balances strength with chip space.
Consistent Accuracy – UNC 2B class for repeatable, in-spec threads.

Technical SpecificationsWhy Choose This Tool?

This Sandvik spiral flute tap combines an HSS-PM substrate, PVD FeN coating, and a 45o helix with a C-chamfer to deliver long life, crisp threads, and excellent chip control in blind holes-perfect for professional production on CNC or manual machines.
