SANDVIK Sandvik HSS-PM Blue Spiral Flute PVD FeN coated Tap 1" UNF, DIN 2184-1 Long Body

Sandvik UNF 1”12 Spiral Flute Tap – Premium Blind-Hole Tapping (DIN 2184-1)

Designed for threading applications in steels, stainless steels, and cast irons (PMK). The 45o spiral flute geometry is optimized for blind holes, efficiently lifting chips out of the hole to maintain thread accuracy and extend tool life. Perfect for both CNC machining centers and conventional setups.

Key Features & Benefits

• High Performance – HSS-E substrate with PVD FeN coating provides durability and wear resistance.
• Optimized for Blind Holes – Spiral flutes at 45o ensure smooth chip evacuation and precise threading.
• DIN 2184-1 Standard – Guarantees compatibility, strength, and repeatability in industrial use.
• Accurate Threads – Manufactured to UNF 2B tolerance class for consistent, in-spec results.
