Hand Tap Rougher DIN 2181 HSS-G - M 80 x 1.5

• 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.
• Process: manual driving or assisted driving depending on your holder and machine setup.
• Use: thread cutting, re tapping, and thread cleaning depending on condition.

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

• 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
• Ground HSS-G execution can help you maintain consistent cutting edges, depending on workpiece material

• 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.

What does rougher mean for a hand tap?

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.

Does the title value M 80 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.

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.

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.
