Dart-Tap BA 2 - ISO 529 - Form C – HSSE-PM

This tap is not only specialized for the unique BA2 threadwhich is the standard for the connection between the barrel and the shaft on darts, but it also stands out due to its material. The HSSE-PM version, made from powder metallurgical thép, offers significantly higher toughness and wear resistance than the standard HSSE version. This makes it the ideal choice for ambitious players, workshops, and anyone looking for an extremely durable and reliable solution.

In our assortment, you will also find other suitable tools for dart thread processing:

• HSSE Tap BA2
• Die BA2

The tap is suitable dùng cho ứng dụng thông dụng under the following conditions:

• For vật liệu dễ gia công đến 1,000 N/mm².
• Especially robust version made of powder metallurgical HSSE-PM thép.
• Optimal for thép không hợp kim và thép hợp kim thấp.
• Suitable for hand and machine use.
• Can be used for lỗ thông and lỗ bít.

Here's how you repair a thread in a dart barrel:

1. Prepare: Clamp the dart barrel firmly and securely in a vice or a holder.
2. Position: Position the tap straight at the thread opening. Use a Tay quay taro for manual use.
3. Cut the thread: Turn the tap carefully and evenly into the ren trong. Pay attention to chip breaking by turning a quarter turn back now and then.
4. Clean: After cutting, remove all chips from the thread.
5. Test: Check the repaired thread by carefully screwing in a new shaft.

What is the difference between a BA2 thread and a metric thread?

The BA2 thread is a fine thread characterized by a special flank angle of 47.5°. It is the established standard for the precise and robust connection between the barrel and shaft on darts.

Can I use this tap for both hand and machine use?

Yes, the tap is versatile. You can use it manually with a Tay quay taro as well as in a machine.

Why is a specialized dart tap important?

Darts are precision tools. A regular tap cannot guarantee the fine tolerances. This special tap ensures that the connection between the shaft and barrel fits perfectly and holds up even under heavy use.

Which materials is this HSSE-PM tap suitable for?

This tap is optimized for easily machinable materials with a tensile strength up to 1,000 N/mm², especially thép không hợp kim và thép hợp kim thấp.

How do I repair a worn ren trong in the dart barrel?

You clamp the barrel and carefully guide the tap into the hole. By cutting a new thread with this special tap, the barrel regains its original functionality.
