Hand Tap Rougher DIN 2181 HSS-G - M 90 x 1.5

• 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 maintenance jobs where controlled tool guidance is important in the first pass.
• 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.

• 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 limited in very abrasive or work hardening materials, depending on cutting conditions and tool execution
• Not ideal when you need high output production cycles where a dedicated machine tap would be more efficient

1. Confirm the thread standard and pitch from your drawing and check that the bore is prepared accordingly.
2. Select a suitable lubricant for your workpiece material and prepare cleaning tools for chip removal.
3. Clamp the workpiece securely and align the tap axis to the bore axis before you start.
4. Mount the tap in an appropriate wrench or holder and ensure the square is clamped without play.
5. Start the tap carefully and apply steady torque while keeping alignment under control.
6. Continue with controlled advancement and clear chips as needed. Technical information hand taps as PDF
7. Remove the tap carefully, clean the thread, and protect the cutting edges before storage.

• 1 piece: Hand Tap Rougher DIN 2181 HSS-G - M 90 x 1.5

• Standard: DIN 2181
• Material: HSS-G
• Tool type: Hand tap rougher
• Thread designation: M 90 x 1.5
• Thread system: Metric internal thread, as designated in the title
• Execution: Ground, depending on variant

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.

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.

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

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

Rougher refers to the first tap stage in a staged hand tapping sequence. You use it to establish the initial thread form and guidance before you use subsequent taps, depending on your set and process.

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.
