Hand Tap Rougher DIN 2181 HSS-G - M 20 x 1.5

• Cutting or reworking internal threads when controlled hand guidance is preferred
• Starting the tap carefully so the tool tracks on axis and follows the intended thread direction
• Using the tool in maintenance, fixture work and smaller batch production where direct feel is valuable
• 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 Select the product by thread designation, workpiece condition and the holder concept used in your process.

• Thread related geometry and designation are clearly assigned in the product name for practical selection
• Suitable for workshop, maintenance and machine room workflows with repeatable tool use
• The explicit standard and material markings support controlled tool assignment in professional use
• A dedicated threading tool reduces compromise compared with improvised general purpose tooling

• Tool selection still depends on matching the thread system, material and process type to the actual job.
• It is intended for defined threading work and not for undirected high speed use without the correct setup and lubrication strategy.

1. Prepare the bore and mount the tap securely in a compatible tap wrench.
2. Start the tap square to the hole with controlled manual pressure.
3. Continue turning while monitoring alignment and the running behavior of the tool.
4. Reverse the tap at controlled intervals to keep the cutting path free.
5. Remove the tap once the thread is completed and clean the bore.
6. Check the finished thread before fitting the mating component.
