Hand Tap Finisher DIN 2181 HSS-G - M 10 x 1.25

This hand tap delivers reliable results in these areas:

• Specifically for grease fitting and lubrication head threads.
• General-purpose use in metalworking workshops.
• Best suited for machinable steels up to 900 N/mm².
• Effective for both through and blind holes.
• Produces metric fine threads per DIN 13; tool manufactured to DIN 2181.

1. Preparation: Drill the correct core hole, deburr carefully, and verify size accuracy.
2. Clamping: Place the tap securely in a wrench; align it square to the hole.
3. Lubrication: Apply cutting oil liberally to tool and hole.
4. Starting: Engage the tap clockwise until it cuts smoothly.
5. Tapping: Rotate steadily, keeping the tap aligned and lubricated.
6. Finishing: Once depth is achieved, reverse out carefully counter-clockwise.
7. Cleaning & Inspection: Remove chips, clean the thread, and verify with a gauge or fitting.

Q1: What is this tap mainly used for?

A1: Especially for grease fitting and lubrication head threads and other fine pitch thread applications.

Q2: What does DIN 2181 stand for?

A2: It is the standard for hand taps (taper, intermediate, finisher) defining dimensions and tolerances for metric ISO threads.

Q3: Why choose HSS-G material?

A3: It provides higher accuracy, smoother threads, and better tool life compared to conventional HSS taps.

Q4: Is this tap designed for machine use?

A4: No, it is primarily intended for manual tapping; machine use is not recommended.

Q5: Which materials can it cut?

A5: Unalloyed and low-alloy steels up to 900 N/mm² tensile strength.
