Hand Tap Rougher DIN 2181 HSS-G - M 90 x 3.0

• Process: manual driving or assisted driving depending on your holder and machine setup.
• Use: thread cutting, re tapping, and thread cleaning depending on condition.
• Use it when you need to match the metric designation and pitch stated in the title.
• Use it for plant engineering assemblies where manual access is limited and alignment matters.
• Use it as the first stage in a staged hand tap sequence when you want a guided thread start.

Note Align the tool carefully and use lubrication suitable for your workpiece material to support surface quality and tool life.

• Useful when you want to reduce corrective rework by creating a clean initial thread path
• Suitable for routine threading tasks in maintenance and fabrication environments
• Supports a staged tapping sequence where the first pass establishes guidance for later tools
• DIN 2181 reference supports standardised selection and documentation in production planning

• May be limited in hard or scale covered surfaces where edge load becomes high at the start of the cut
• Not intended for fully automated high speed tapping where machine tool synchronisation is required

1. Check the drawing for the required thread designation and confirm the pitch matches the title.
2. Inspect the bore and remove burrs so the tap can enter without side load.
3. Choose lubrication suitable for the material and apply it to the tool and entry area.
4. Clamp the tap securely in a wrench or holder and ensure the tool is guided straight.
5. Begin tapping with steady torque and keep the tool aligned to reduce thread start marking.
6. Advance in a controlled manner and clean chips from the flute space when needed. Technical information hand taps as PDF
7. Back the tool out smoothly, clean the thread, and preserve the tool with light protection oil if used in your shop.

• 1 piece: Hand Tap Rougher DIN 2181 HSS-G - M 90 x 3.0

• Standard: DIN 2181
• Material: HSS-G
• Tool type: Hand tap rougher
• Thread designation: M 90 x 3.0
• Thread system: Metric internal thread, as designated in the title
• Execution: Ground, depending on variant

What should you watch for to avoid flank damage at the thread start?

Keep the tool aligned to the bore axis and apply steady torque. Use a suitable lubricant and avoid forcing the tap when resistance rises, because misalignment can mark the first thread turns.

Does the title value M 90 x 3.0 include the pitch information you need?

Yes. The thread designation in the title includes both diameter and pitch, which helps you distinguish fine pitch variants from other executions of the same nominal diameter.

Which holder or wrench is appropriate?

Use a tap wrench or suitable holder that clamps the square reliably and keeps the tool aligned. Select the interface based on your tap size and your available guidance method.

How do you handle chips during tapping?

Use suitable lubrication and advance with controlled torque so chips can evacuate through the flute space. Clean the tool as needed to avoid chip packing and surface scoring.

What is the role of the DIN 2181 reference?

DIN 2181 supports standardised identification for hand taps. It helps you align purchasing, documentation, and workshop instructions with a recognised designation.

How do you select the correct variant for your drawing?

Match the metric thread designation in your drawing to the product title, including the pitch value, because the pitch differentiates otherwise similar diameters.
