Straight Flute DIN 371 Machine Tap
Application: Ideal for threading blind or through holes in steel, stainless steel, cast iron, and nonferrous materials. Its ground teeth and chamfer covering 2-3 threads make it suitable for thread depths less than 2 times the tap diameter (2d1).
Recommended Use: This type is particularly effective for hand tapping due to its straight flutes, offering stability and ease of use.
Spiral Point DIN 371 Machine Tap
Application: Designed for creating threads in through holes, this tap features ground teeth and a chamfer of 4-5 threads. It’s effective for thread depths up to 3 times the tap diameter (3d1) in steel, stainless steel, and cast iron.
Recommended Use: The spiral point pushes chips forward, making it ideal for through holes where chip evacuation is straightforward.
Fast Spiral Flute 35º DIN 371 Machine Tap
Application: This tap is designed for blind holes in steel, stainless steel, cast iron, and nonferrous materials with thread depths up to 2.5 times the tap diameter (2.5d1). The 35º fast spiral flute aids in efficient chip evacuation.
Recommended Use: Suitable for CNC machines where high-speed threading and precision are paramount.
Slow Spiral Flute 15º DIN 371 Machine Tap
Application: Like its fast spiral counterpart, this tap is used for blind holes in similar materials, but with a thread depth limit of 2 times the tap diameter (2d1). The 15º slow spiral flute offers controlled chip removal.
Recommended Use: Recommended for materials that produce long, stringy chips, ensuring a cleaner threading process.
Coating Options
Bright, TiN (Titanium Nitride), TiCN (Titanium Carbonitride): These coatings enhance the tap’s durability, heat resistance, and lubricity, thereby increasing tool life and performance in various materials.
Each of these taps can be specifically tailored for use in different machining environments, depending on the material, hole type, and desired thread depth. It’s crucial to select the right type of DIN 371 machine tap for each application to ensure optimal performance and longevity of the tool.
