Hand Tap Rougher DIN 2181 HSS-G - M 76 x 1.5

• 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 toolroom operations where you manage torque and alignment by feel and by setup.
• Use it as the first stage in a staged hand tap sequence when you want a guided thread start.
• Process: manual driving or assisted driving depending on your holder and machine setup.

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 restricted when the workpiece material promotes built up edge, depending on lubricant selection
• Less efficient for large series work where process time and consistent feed control are critical

1. Verify the required internal thread on the drawing and match it to the product title.
2. Prepare the bore entry by removing sharp edges and ensuring the tap can start square.
3. Select cutting lubricant appropriate for the workpiece and apply it before engaging the tool.
4. Secure the tap in a suitable holder and check that the tool runs true by hand.
5. Drive the tap with controlled torque while maintaining straight guidance along the bore axis.
6. Maintain chip evacuation by periodic cleaning and continued lubrication as required. Technical information hand taps as PDF
7. Withdraw the tap, clean the thread form, and store the tool in a protected environment.

• 1 piece: Hand Tap Rougher DIN 2181 HSS-G - M 76 x 1.5

• Standard: DIN 2181
• Material: HSS-G
• Tool type: Hand tap rougher
• Thread designation: M 76 x 1.5
• Thread system: Metric internal thread, as designated in the title
• Execution: Ground, depending on variant

How do you select the correct variant for your drawing?

Match the metric thread designation in your drawing to the product title M 76 x 1.5, including the pitch value, because the pitch differentiates otherwise similar diameters.

Does the title value M 76 x 1.5 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.

Can you use this hand tap for thread cleaning or repair work?

You can use it for controlled re tapping and for cleaning of existing threads when the thread form is intact, but the result depends on thread condition and how much material must be removed.

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.

How do you decide between hand tapping and machine tapping?

Hand tapping is useful when you need tactile control or when access is limited. Machine tapping is typically chosen when you need consistent feed synchronisation and higher throughput.

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.
