Hand Tap Rougher DIN 2181 HSS-G - M 17 x 1.5

• for manual preparation of an internal thread as the first stage before follow-up hand taps
• for M 17 x 1.5 when the thread size and pitch match the workpiece drawing
• for tool room, maintenance, and repair work where controlled hand tapping is required
• 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 Use the rougher as the starting tap and continue only with matching follow-up taps from the same thread size and standard.

• Rougher geometry supports the controlled first cut before the next hand tap stage.
• HSS-G material is stated in the product data and supports accurate manual tapping in suitable workpiece materials.
• DIN 2181 identification helps you match the tool to the required hand tap series.
• The visible thread designation M 17 x 1.5 gives the decisive size and pitch for selection.

• A rougher alone does not complete a full hand-tapped internal thread, so use matching follow-up taps where the process requires a complete set.

1. Check the thread designation against the drawing and select the matching holder before starting.
2. Prepare the drilled hole and chamfer according to the thread process used in your workshop.
3. Apply suitable cutting fluid for the workpiece material and tool setup.
4. Start the rougher square to the hole axis and drive it with steady alignment control.
5. Reverse carefully when needed to clear chips without forcing the tap.
6. Remove the rougher and clean the hole before using the next matching hand tap stage.
7. Inspect the finished thread before assembly or further processing.

• 1 piece Hand Tap Rougher DIN 2181 HSS-G - M 17 x 1.5

• Product type: hand tap rougher
• Thread system: M
• Thread designation: M 17 x 1.5

What part of the tapping process does this rougher cover?

It covers the first manual cutting stage for M 17 x 1.5 and prepares the internal thread for the following hand tap stages.

Do you still need further taps after the rougher?

Yes, use matching follow-up taps when the hand tapping process requires a complete thread profile and final sizing.

How do you select the correct hand tap rougher?

Select the rougher by thread designation, pitch, DIN series, material specification, and the required hand tapping sequence.

Can the rougher be used for thread cleaning?

You may use it for re tapping or cleaning only when the thread condition and workpiece allow controlled manual guidance.

What should you check before ordering?

Check whether you need only the rougher or a complete hand tap set, because a single rougher does not replace the intermediate or finishing tap.
