Hand Tap Rougher DIN 2181 HSS-G - M 105 x 4.0

• 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 internal thread cutting in common engineering materials, depending on cutting conditions.
• 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.

• DIN 2181 reference supports standardised selection and documentation in production planning
• 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

• May not be suitable for very tough materials without a controlled process and appropriate lubrication
• Not optimised for high performance automated lines where tool life tracking is tightly controlled

1. Confirm thread requirements on the drawing and verify that the pitch is correct for the part.
2. Clean the bore and remove chips or contamination that can skew alignment at entry.
3. Apply suitable lubrication to reduce friction and improve surface finish in the thread.
4. Clamp the tool in a stable wrench or holder and set up guidance if available.
5. Start with careful alignment and controlled torque so the first turns form cleanly.
6. Continue the cut with steady motion and remove chips from the cutting area when necessary. Technical information hand taps as PDF
7. Remove the tool, clean the work area, and check the thread with an appropriate inspection method.

• 1 piece: Hand Tap Rougher DIN 2181 HSS-G - M 105 x 4.0

• Standard: DIN 2181
• Material: HSS-G
• Tool type: Hand tap rougher
• Thread designation: M 105 x 4.0
• Thread system: Metric internal thread, as designated in the title
• Execution: Ground, depending on variant

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.

Does the title value M 105 x 4.0 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.

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.

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.
