Mũi taro ren tay (tạo ren trong) Finisher DIN 352 HSS-G - M 12 x 1.75

• Cut ren trong in lỗ thông or lỗ bít when you need manual control of the tapping process.
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: cắt ren, taro lại ren, and làm sạch ren depending on condition
• Use cutting fluid suitable for the material and keep the tool square to the hole axis.

Lưu ý Verify the thread designation before starting and check the first turns for square alignment.

• Manual control over torque and alignment during cắt ren
• Suitable for workshop repair, maintenance, and low volume production
• Practical for starting threads in assembled or hard to fixture parts
• Ground tool geometry can support consistent cutting action

• Not suitable for abrasive or highly work hardening materials without adapted process control
• Not intended for high performance cycle times in mass production

1. Prepare the hole with the correct pre machining and add a small entry chamfer.
2. Secure the workpiece so it cannot move during tapping.
3. Clamp the tap in a suitable Tay quay taro and bring it to the hole axis squarely.
4. Apply a cutting fluid matched to the workpiece material.
5. Start the first turns with steady pressure while keeping alignment.
6. Advance with controlled torque and reverse slightly at intervals to clear chips from the flutes.
7. Continue until the required thread depth is reached, then back out smoothly.
8. Clean the thread and inspect fit with a gauge or mating part.

• 1 chiếc Mũi taro ren tay (tạo ren trong) Finisher DIN 352 HSS-G - M 12 x 1.75

• Product type: Mũi taro ren tay (tạo ren trong)
• Standard: DIN 352
• Tool material: HSS-G
• Thread designation: M 12 x 1.75
• Thread system: ren hệ mét ISO

How do you select the correct thread designation for this tool
Match the designation M 12 x 1.75 to the drawing and mating part, then confirm that the hole type and process match the tool design.

Which holder is typically used for manual tapping
A Tay quay taro that clamps the square shank is the typical choice, and you keep the tool axis aligned to the hole to reduce side load.

What does the stage name in the product name tell you
Stage names such as rougher, intermediate, finisher, taper, or bottoming indicate the intended chamfer and entry behavior, so you can plan the tapping sequence and hole depth.

Which workpiece materials are typical for this threading tool
cắt ren tools are commonly used in steels, cast iron, and many non ferrous alloys, but you should adapt Chất bôi trơn cắt gọt ren choice and process control for hard, sticky, or abrasive materials.

What does ren hệ mét ISO mean in the thread designation
M indicates a ren hệ mét ISO system used widely in general mechanical engineering.

Do you need lubrication and how do you manage chips
Use a cutting fluid suitable for the material to reduce friction, and clear chips from the flutes during the process to keep torque stable.
