Machine Tap set M4-M10, Form C 35° RSP, extra long - 150 mm

• Use for internal thread 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.
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: thread cutting, re tapping, and thread cleaning depending on condition

Note Select the thread system and nominal size from the product title to match the drawing and the mating part.

• Supports consistent internal thread quality when tool alignment and hole preparation are controlled.
• Suitable for mechanical engineering and maintenance work where repeatable fits are required.

• 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.

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.

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.
