Hand Tap set of 2 pieces DIN 2181 HSS-G - M 27 x 1.0

• Suitable for general use.
• Designed for non-abrasive materials up to 900 N/mm².
• Ideal for unalloyed and low alloy steels.
• For through and blind holes.
• Optimized for precise manual thread cutting.
• Ground HSS-G execution for high cutting quality and long durability.

1. Taper Tap: Starts the thread and forms the correct profile.
2. Plug Tap: Finishes the thread cleanly and accurately.

The ground HSS-G material ensures optimum chip evacuation and precise threading results.

1. Drill the core hole: Drill according to the core hole diameter (26.0 mm).
2. Deburr the hole: Ensures clean thread engagement.
3. Insert the taper tap: Align straight and turn evenly by hand.
4. Insert the plug tap: Complete the thread cleanly after taper tapping.
5. Final inspection: Clean and check the thread for accuracy.

Q1: Which materials is this tap set suitable for?

It is ideal for non-abrasive materials up to 900 N/mm² as well as unalloyed and low alloy steels. It also works well in softer non-ferrous metals.

Q2: Can I use the set for blind holes?

Yes. Both taper and plug taps are designed for through and blind holes.

Q3: Why is this set made of two taps?

For large fine threads such as M27 x 1.0, a 2-piece set (taper & plug tap) is sufficient, allowing faster work without sacrificing precision.

Q4: Do I need a tap wrench?

Yes, a stable tap wrench with a 16 mm square drive is required for proper leverage and control.

Q5: Should I use cutting oil?

Absolutely. Cutting oil reduces friction, prevents heat buildup, increases tool life, and significantly improves thread quality.

Q6: Can I use these taps in a machine?

No. This tap set is designed exclusively for manual use. Machine operation may damage the tools or cause thread breakage.
