The OSG UNF Spiral Flute Threading Tap is designed for precision threading in blind holes, ideal for machinists who demand durable, accurate internal threads in tough metals.
- UNF Thread Form: Unified National Fine pitch for precise, tightly engaging internal threads in small-diameter holes.
- Spiral Flute Design: Optimizes chip evacuation in blind holes, reducing binding and the risk of tap breakage during deep or restricted-depth tapping.
- Material: High-speed steel with cobalt (HSS-E) for enhanced hardness and heat resistance during demanding tapping operations.
- Coating: Steam oxide coating provides wear resistance and helps dissipate heat, extending tool life in challenging materials.
- Application: Specifically engineered for blind-hole threading in metalwork where access is from one side only.
- Size: No. 5 x 44, tailored for internal threads in smaller-diameter components.
Using this tap delivers consistent, high-quality threads with reduced tool wear and fewer interruptions. The HSS-E composition handles tougher alloys, while the spiral flute design aids chip control in confined spaces. The steam oxide coating minimizes friction and protects the cutting edges, helping you achieve clean finishes and reliable fits in critical machining tasks.
