Mũi taro máy ngắn DIN 352 Form C 35° Spiral Flute HSSE - M 4 x 0.7

• Create metric ISO ren trong in thép and comparable alloys, depending on the workpiece condition and cutting fluid.
• Use when you need chip transport toward the entry, as typical for spiral flute taps.
• Often selected for hole types where chips should not be pushed forward to the bottom.
• Applied in production and maintenance work where thread quality and chip control matter.
• 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 Ensure the hole has enough depth for the planned thread, use lubrication, and remove chips from the flute before you continue.

• Spiral flute geometry supports chip transport toward the entry
• Compact DIN 352 body supports space limited setups
• HSSE tool material supports stable cutting edges
• Spiral flute design supports cleaner thread flanks in many cases
• ren hệ mét ISO focus supports common assemblies

• Not suitable for very hard or highly abrasive materials, depending on execution
• Not intended for high performance tapping without rigid guidance and controlled coolant

1. Confirm the required thread specification before you start.
2. Create a clean pilot hole and ensure enough depth for the thread.
3. Secure the workpiece and align the tool axis to the hole.
4. Clamp the tap in a suitable holder.
5. Apply suitable lubrication for cutting.
6. Tap with controlled feed and avoid sudden speed changes.
7. Stop if you notice abnormal torque and clear chips.
8. Remove the tap, clean the thread, and verify fit.

What is the benefit of a spiral flute tap in internal threading?

A spiral flute tap typically transports chips back toward the entry, which can support a cleaner cut when chips should not be pushed forward. Always keep chip evacuation under control and avoid forcing the tool.

When do you choose Form C instead of Form B?

Form C spiral flute execution is commonly chosen when chip transport to the entry is desired. Form B is often used when chips can move forward, depending on hole design and process setup.

Can you use the tool in the size M 4 x 0.7 by hand and in a machine?

Yes, depending on your holder and setup you can drive the tool by hand or with a machine. Focus on alignment, lubrication, and controlled torque to protect the cutting edges.

What lubrication should you use for cắt ren?

Use a cutting fluid suitable for the workpiece material and the tapping method. Stable lubrication supports surface quality and helps control torque.

Can you use the tool for taro lại ren an existing thread?

Yes, depending on thread condition you can use it to clean up damaged flanks. Keep torque low and stop if the tool binds, because the cutting edges are not made for removing large amounts of material.

Where can you find technical background on short machine taps and selection criteria?

Use this document for selection guidance and general process parameters: Technical information short machine taps as PDF.

How do you know when the tap is worn?

Typical signs are rising torque, rough thread flanks, and inconsistent fit with the mating part. Replace the tap if the cutting edges look rounded or chipped.
