Mũi taro nén ren without oil groove DIN 376 Form C HSSE TiN - M 12 x 1.75

• Forming of ren trong in ductile materials where chip free processing is preferred
• Use in production and maintenance when thread flank quality and repeatability are required
• Suitable for lỗ thông and lỗ bít when the correct geometry is selected from the product name
• Use with a tapping chuck or suitable collet holder to keep axial alignment during the tapping cycle
• 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

Lưu ý For consistent results you verify thread designation on the drawing and match it to the execution in the product name.

• Good thread surface due to forming action when material ductility is sufficient
• Often improved tool life when lubrication and material are suitable
• Stable thread profile when alignment and pre hole preparation are controlled
• Chip free process can reduce cleaning effort in certain materials

• Requires ductile workpiece materials and correct pre hole preparation to avoid excessive torque
• Not suitable for high performance applications when process limits are not controlled

1. Confirm the thread designation, standard, and execution in the product name against your drawing and material specification.
2. Prepare the pre hole and entry chamfer according to your process specification and remove burrs from the opening.
3. Clamp the tap in a tapping chuck or suitable collet holder and set up the cycle so feed stays synchronised with rotation.
4. Apply a suitable cutting Chất bôi trơn cắt gọt ren or coolant for the workpiece material and ensure the entry area is wet.
5. Start the cut with the tool aligned to the hole axis and keep the alignment stable through the first turns or revolutions.
6. Run the forming pass with steady feed and stop the process if torque rises sharply due to insufficient lubrication or material suitability.
7. Retract the tool, clean chips from the flutes, and inspect the thread before the part moves to the next operation.

What should you check before you start tapping with this tool? You verify the thread designation shown in the product name and confirm that your pre hole preparation meets your internal process specification. You also check the workpiece material and choose a Chất bôi trơn cắt gọt ren that prevents seizing. Which holder type do you typically use with this tap? You typically use a tapping chuck or a suitable collet holder so the tap runs concentrically and stays aligned. If your process needs axial compensation, you choose a holder that provides it. How do you reduce the risk of broken taps and damaged threads? You keep the tool aligned, use a suitable Chất bôi trơn cắt gọt ren, and monitor torque so you can stop before overload. You also remove chips from the flutes and avoid starting on burrs or hard scale. Where can you read more about fluteless tapping requirements? Use the PDF for consolidated notes on selection and handling. Technical information fluteless machine taps as PDF Do you need cutting Chất bôi trơn cắt gọt ren or coolant for this tap? Yes, you use a Chất bôi trơn cắt gọt ren or coolant matched to the workpiece material to reduce friction and to control heat. Stable lubrication also helps keep thread flank quality consistent. How do you maintain and store the tap after use? You clean chips from the flutes, dry the tool, and apply a light corrosion protection film. You store it so cutting edges are protected from contact and impact. Where can you find additional technical data and the full range? Use the catalog for overview tables and selection guidance.
