Hand Tap Rougher DIN 2181 HSS-G - M 86 x 1.5

• Use it for mechanical engineering and metal fabrication where you need a predictable thread start.
• 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.
• 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.

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

• Ground HSS-G execution can help you maintain consistent cutting edges, depending on workpiece material
• Helps you control alignment at the start of the thread when combined with a suitable wrench and guidance
• The title based size and pitch marking simplifies variant selection across similar diameters
• Can support repeatable results when you keep lubrication, alignment, and chip evacuation consistent

• 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 86 x 1.5

• Standard: DIN 2181
• Material: HSS-G
• Tool type: Hand tap rougher
• Thread designation: M 86 x 1.5
• 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 86 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.

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.
