Walter Prototyp M2356305-UNF9 16 Spiral Flute Tap

Description:

The Walter Prototyp M2356305-UNF9/16 Spiral Flute Tap is used in industrial machining and threading systems for producing precise 9/16"-18 UNF internal threads in metal components and production assemblies. Commonly installed in CNC machining centers, tapping machines, production lathes, and industrial manufacturing systems. Maintenance teams, machinists, and manufacturing engineers use this tap for thread cutting, tooling replacement, production machining, and repair of threaded mechanical components.

Applications:

The Walter Prototyp M2356305-UNF9/16 spiral flute tap is designed for industrial threading operations requiring accurate thread formation, efficient chip evacuation, and reliable cutting performance in blind-hole applications. It is frequently utilized in aerospace machining, automotive manufacturing, hydraulic component production, machine building, metal fabrication facilities, and precision engineering environments where consistent thread quality, dimensional accuracy, and extended tool life are critical for maintaining manufacturing efficiency and product integrity. Spiral flute taps are especially effective for blind-hole threading because they evacuate chips upward through the flutes.
