HexDrive Threading Tool Set P.K.335, Form B, HSS-E, M 3-12

• Designed for cutting metric ren trong in lỗ thông in free-cutting materials up to 900 N/mm².
• Form B is used when chips are to be evacuated in a controlled manner in the machining direction and free chip flow is ensured.
• Suitable for thép không hợp kim và thép hợp kim thấp in typical workshop and production environments.
• HexDrive shank enables a positive-fit connection for secure power transmission in the drive system.
• Process: manual or assisted drive depending on your threading tool holder and machine configuration.
• Use: cắt ren, re-tapping and làm sạch ren depending on the condition of the thread.

Lưu ý For lỗ thông, precise alignment is essential so that the tap starts evenly and the thread flanks are formed without offset.

• Tool combination for through-threading processes with clearly defined chip evacuation.
• HSS-E cutting material for reliable performance during continuous machining and stable cutting conditions.
• Form B geometry supports unrestricted chip transport out of the workpiece.
• HexDrive shank reduces the risk of slipping in the holder under increasing load.
• Ready-to-use set with matched twist drills for consistent process preparation.
• Efficient for workstations with varying thread requirements within a defined size range.

• Not ideal for lỗ bít, as the geometry is designed for continuous chip evacuation through the workpiece.
• For highly specialized high-performance processes, a more material- or process-optimized individual solution from the threading tools range may be required.

1. Determine the required thread size and select the corresponding tap and matching Mũi khoan xoắn from the set.
2. Create the core hole with an even feed movement so that the initial hole is dimensionally accurate and straight.
3. Clamp the tap firmly in the holder so that secure torque transmission is achieved without play.
4. Position the tool precisely to the hole and start the cutting process with steady feed.
5. Guide the tap continuously through the workpiece so that the chips can exit freely to the front.
6. During machining, ensure smooth running without sudden loading of the tool.
7. After the full pass, withdraw the tap in a controlled manner.
8. Check the thread for dimensional accuracy and clean thread flank formation.
9. Clean the tools used and store them protected for the next operation.

Why is this set especially suitable for lỗ thông?
The tool geometry is designed so that chips exit the workpiece in the feed direction. This creates a free machining area without material build-up.

What are the advantages of a complete threading tool set in daily use?
You have all the tools needed for several thread sizes readily available and can standardize workflows without having to assemble each tool individually.

What distinguishes Form B from other tap forms?
Form B is designed for lỗ thông and supports continuous forward chip flow, while other forms are designed for different machining situations.

What role does the Mũi khoan xoắn play in the overall process?
The Mũi khoan xoắn creates the basis for the later thread. A matching core hole ensures that the tap works cleanly and that the thread is formed correctly.

When should I not use the set?
If you are working with lỗ bít or machining very demanding materials, the tool selection should be specifically adapted to the respective machining situation.

How does the HexDrive shank support the work process?
The positive-fit connection allows torque to be transmitted securely, enabling a stable and controlled cutting process. Suitable threading tool holders can further support secure tool guidance.
