BLACK RING Mũi taro máy DIN 376 Form C HSSE NIT - M 33 x 3.5

• Use for ren trong production in prepared holes in common engineering materials, within the limits of the tool grade.
• Use in workshop production where stable alignment and adequate lubrication are available.
• Use the ring marking in the title for fast identification when multiple tap types are stored together.
• 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 Select the thread system and nominal size from the product title to match the drawing and the mating part.

• Suitable for mechanical engineering and maintenance work where repeatable fits are required.
• Surface treatment NIT in the title can reduce friction and improve running behaviour in suitable materials.
• Tool material is HSSE as stated in the title which supports wear resistance in continuous use.
• Supports consistent ren trong quality when tool alignment and hole preparation are controlled.
• Ring marking supports quick selection in tool cabinets and reduces mix ups during changeover.

• Not suitable for materials outside the hardness and toughness range intended for the tool grade.
• Requires clean hole preparation and stable guidance, so it is not ideal for high throughput rough setups.

1. Confirm the thread system and nominal size in the product title against your drawing and mating part.
2. Prepare the hole with the correct drilling operation and remove burrs from the entry.
3. Select a suitable holder that keeps the tap aligned and provides controlled torque.
4. Apply a cutting fluid appropriate for the workpiece material and the selected tap type.
5. Start tapping with steady alignment and keep the axis straight to avoid flank damage.
6. Advance with controlled feed and clear chips from the flutes as needed without forcing the tool.
7. Stop at the required thread depth and withdraw the tap while maintaining alignment.
8. Clean the thread and verify fit with the mating part or with a suitable gauge.
9. Clean and protect the tool before storage to reduce corrosion and edge damage.

Which hole type is this tap geometry aimed at

Choose the geometry based on hole type and chip transport needs, as indicated by the flute or form information in the product title.

Where can you find geometry and application background for machine taps

Use the technical information for guidance on tap types, geometry terms, and general application limits. Technical information machine taps as PDF

What does Form B or Form C indicate

Form letters describe the lead and entry geometry that influences how the tool starts and how load builds up. Use the form stated in the title as a selection cue aligned with your thread depth and material behaviour.

Which tolerance class do you normally target with standard taps

Standard taps are commonly used for the usual fit class of the thread system. If your drawing calls for a special fit, select a dedicated tolerance execution rather than a general purpose tap.

How do you use ring markings for tool management

Ring markings support quick sorting of taps by geometry or application focus in storage and on the shop floor. Use the marking as an identification aid and still confirm the full designation before use.

Where can you find the colour ring identification overview

Use the coloured ring document for the meaning of ring markings across the range. Technical information coloured ring identification as PDF

Can you use one tap for both production and rework

You can use a suitable tap for controlled production and for careful rework when the thread is not severely damaged. For heavy rework, consider whether the base material and the thread profile still support clean cutting.
