Emkay Fractional BS-949 SS Spiral flute (UNC/ UNF/ BSW/ BSF)

Features of Emkay Fractional BS-949 SS Spiral Flute Taps (UNC / UNF / BSW / BSF)

1. High-Quality HSS Construction – Made from premium High-Speed Steel (HSS) for excellent hardness, durability, and wear resistance.

2. Spiral Flute Design – Engineered for efficient chip evacuation, especially ideal for blind hole tapping.

3. Compatible Thread Standards – Supports UNC, UNF, BSW, and BSF thread forms for a wide range of applications.

4. Fractional (Inch-Based) Sizing – Manufactured in imperial sizes as per BS-949 standards, suitable for British and Unified threads.

5. Smooth Cutting Action – Spiral flutes provide a clean finish and reduce torque, improving tool life.

6. Ideal for Blind Holes – Spiral flutes pull chips upward, making them perfect for tapping deep or closed-end holes.

7. Precision Ground Threads – Delivers accurate thread profiles with tight tolerance and smooth entry.

8. Durable and Heat-Resistant – Performs efficiently under high-speed and high-temperature conditions.

9. Versatile Material Use – Suitable for threading steel, stainless steel, aluminum, brass, and cast iron.

10. Machine and Manual Use – Compatible with manual tap wrenches and CNC/automated tapping systems.

Applications For uses : 

1. Blind Hole Tapping – Ideal for creating internal threads in closed-end holes, where chip removal is crucial.

2. Precision Engineering – Used in high-precision components requiring Unified or Whitworth threads.

3. Automotive & Aerospace Components – Perfect for threading parts like engine blocks, housings, and structural assemblies.

4. General Manufacturing & Fabrication – Widely used in industrial production lines for accurate threading in inch sizes.

5. Metalworking and Tool Rooms – Suitable for both manual and CNC machine tapping across various metals.

6. Maintenance & Repair Operations (MRO) – Useful for restoring damaged threads in mechanical equipment and structures.

7. Construction & Infrastructure Projects – For tapping threads in structural steel and support frames using imperial standards.

8. Marine & Railways – Ideal for industries that follow BSW/BSF standards for component assembly and maintenance.

9. Educational Training – Great for learning blind hole tapping techniques and thread standards in technical institutions.

10. Custom Fabrication Jobs – Preferred in bespoke or prototype manufacturing requiring inch-based spiral flute taps.
