Tap Set for grease nipples

Every mechanic knows: no lubrication – no machine runs for long. A grease nipple thread ensures a secure and leak-free connection between the fitting and the component. If the thread is stripped, corroded, or contaminated, the fitting cannot stay in place and grease will not reach the bearing point.

Problems caused by defective threads include:

• Loss of lubrication leading to bearing or joint failure
• Grease leakage and contamination of surrounding parts
• Loose fittings that fall out under vibration

The VÖLKEL tap set allows you to recut or clean damaged threads instantly, keeping vehicles, agricultural machines, and industrial equipment running safely and reliably.

The set includes six of the most frequently used thread sizes worldwide. Each tap has been selected because it matches the most common fittings used on trucks, tractors, construction machinery, and industrial equipment:

• M 6 x 1.0 – Common on smaller machines, motorcycles, and light equipment.
• M 8 x 1.0 – A standard size for medium-duty grease fittings used in general machinery.
• M 10 x 1.0 – Widely used in automotive and heavy-duty applications, especially in Europe and Asia.
• M 10 x 1.25 – Fine pitch version for a tighter and more secure fit, often used where vibration resistance is critical.
• G 1/8 x 28 (BSPP) – Cylindrical British Standard Pipe thread, common in hydraulic and industrial fittings worldwide.
• G 1/4 x 19 (BSPP) – Larger BSP size, frequently used in agriculture and construction equipment.

All taps are made from precision-ground HSS-G (High-Speed Steel) and stored in a durable plastic case with foam insert – ready for use in workshops or in the field.

• Thread types: Metric ISO and BSP (British Standard Pipe)
• Material: HSS-G – precision-ground for accuracy and durability
• Packaging: Plastic case with foam insert
• EAN: 4022835470083
• Article number: 47008

1. Select the right tap: Determine the grease fitting size and choose the corresponding tap from the kit.
2. Preparation: Remove the damaged fitting and clean the area thoroughly from grease, dirt, and rust.
3. Insert the tap: Carefully place the tap straight into the hole and begin turning clockwise with light pressure.
4. Recut the thread: Rotate steadily. Apply cutting oil to ensure smooth operation and protect the tool.
5. Finish and reinstall: Remove chips, clean the repaired thread, and screw in the new grease fitting securely.

1. Who is this set designed for?
Mechanics, service technicians, and maintenance teams in automotive, agricultural, and industrial sectors – worldwide.

2. Why are both metric and BSP threads included?
Because international equipment uses both systems. This set ensures you’re covered whether you work on European, Asian, or Anglo-American machines.

3. Can I use these taps in the field?
Absolutely – the compact case makes the set perfect for mobile use in workshops, garages, or directly on-site.

4. Are these taps durable enough for frequent use?
Yes. Made from HSS-G, they offer excellent wear resistance and long service life.

5. Is this set only for repairing threads?
Yes, it is optimized for recutting and cleaning damaged threads. For cutting completely new threads, a full tap set (taper, plug, bottoming) is required.
