Round Die BS 1127; 1950 (o/d 1.5/16) HSS - BSF 1/2 x 16

Areas of application:

• Universal use for cutting external threads in various materials.
• Ideal for processing easy-to-machine materials with a tensile strength of up to 800 N/mm².
• Suitable for unalloyed and low-alloy steels.

Benefits:

• High-Quality Material (HSS): High Speed Steel ensures high wear resistance and a long service life for the tool.
• Precise Threads: The die is manufactured according to the British Standard Fine Thread (BSF 84) norm, ensuring high accuracy of the cut threads.
• Robust Construction: The round design provides stable guidance and efficient chip evacuation during the cutting process.
• Versatility: Suitable for a wide range of standard applications in metalworking.

Using the die for precise external threads involves three steps:

1. Material Preparation: Start with a carefully prepared workpiece. The material's diameter should correspond to the core diameter required for a BSF 1/2 x 16 thread. The surface must be clean, free of burrs, and as flat as possible to ensure a clean thread start.
2. Clamping the Die: Precisely insert the die into a suitable die stock. Ensure correct centering and a secure fit to prevent tilting during the cutting process. A well-fixed die is crucial for a straight and precise thread.
3. Thread Cutting: Apply the die to the prepared material with light but steady pressure. Rotate the die clockwise (for right-hand threads) at a uniform speed until the desired thread is cut. Always use an appropriate cutting oil. This cools the tool and the workpiece, reduces friction, and significantly improves both the surface quality of the thread and the service life of the die.

1. What is the difference between BSF and BSW threads?
BSF (British Standard Fine) and BSW (British Standard Whitworth) are both British thread standards. The main difference lies in the thread pitch. BSF threads have a finer pitch and are generally used for applications requiring higher strength and finer adjustment. BSW threads are coarser and are often used for more general fastening tasks.

2. What is the outer diameter of the die?
The die has an outer diameter of 1.5/16 inches (o/d). This outer diameter is standardized and ensures that the die fits into the corresponding die stocks.

3. What does HSS stand for?
HSS stands for "High Speed Steel." It is an alloyed tool steel that retains its hardness and cutting performance even at high temperatures that can arise during machining. This makes HSS tools very wear-resistant and durable.

4. Can I use this die for stainless steel?
This die is primarily designed for easy-to-machine materials up to 800 N/mm², such as unalloyed and low-alloy steels. For stainless steel, which generally has higher strength and toughness, we recommend using dies made of HSS-E (with cobalt additive) or solid carbide, as these materials offer better heat dissipation and higher hardness for such demanding applications.

5. How do I maintain the die to extend its service life?
After each use, the die should be thoroughly cleaned of chips and residues. Store it in a dry, protected place to prevent corrosion and mechanical damage. Applying a light rust-preventative oil before storage is also recommended. Regular maintenance significantly contributes to extending the service life and maintaining the cutting performance.
