Application

The VÖLKEL Tap Set for Grease Nipples is designed for servicing, cleaning and reworking common grease nipple threads on vehicles, agricultural machinery, construction equipment and industrial systems. The compact set contains six HSS-G hand tap finishers for metric ISO and G (BSP) pipe threads and covers the frequently used sizes M 6 x 1.0, M 8 x 1.0, M 10 x 1.0, M 10 x 1.25, G 1/8 x 28 and G 1/4 x 19.

Grease nipples must sit securely and cleanly in the component so lubricant can reliably reach bearings, joints and other moving parts. Dirt, corrosion or minor thread damage can prevent a grease fitting from being installed correctly. The included finishers allow existing internal threads to be cleaned and re-tapped in a controlled way. All tools are organised in a plastic case with a foam insert.

Application

  • for re-tapping and cleaning existing grease nipple threads
  • for grease fitting ports on vehicles, agricultural machinery, construction equipment and industrial systems
  • for metric ISO threads M 6 x 1.0, M 8 x 1.0, M 10 x 1.0 and M 10 x 1.25
  • for parallel G (BSP) pipe threads G 1/8 x 28 and G 1/4 x 19
  • for general-purpose use
  • for readily machinable materials up to 900 N/mm²
  • for unalloyed and low-alloy steels
  • for maintenance, servicing and repair directly on the component
  • for controlled manual use with a suitable tap wrench or holder

Note: Always identify the existing grease nipple thread before re-tapping. Metric and G (BSP) thread systems must not be confused. The set is primarily intended for re-tapping and cleaning existing threads. For producing a completely new internal thread, use a complete hand tap set with the required tapping stages.

Benefits

  • six commonly used grease nipple thread sizes in one compact case
  • metric ISO and G (BSP) pipe threads together for servicing different types of vehicles and machinery
  • HSS-G finishers with ground cutting geometry for precise thread reworking
  • clear selection by thread system and size helps reduce mistakes during maintenance
  • ideal for workshops, service vehicles and mobile maintenance
  • individual linked VÖLKEL item numbers simplify replacement and reordering
  • plastic case with foam insert protects the tools and keeps the set organised
Drawback
  • If an internal thread is stripped or severely damaged and no longer has enough sound base material, re-tapping is not sufficient. Use a suitable VÖLKEL thread repair solution instead.

Step by step

  1. Identify the thread system and size of the existing grease nipple.
  2. Remove the grease nipple and clean grease, dirt, corrosion and loose residue from the threaded port.
  3. Select the exact matching finisher from the case.
  4. Secure the tap in a suitable tap wrench or tool holder.
  5. Align the tap with the existing thread axis and apply a cutting fluid suitable for the workpiece material.
  6. Turn the finisher carefully into the existing thread while avoiding side load and excessive torque.
  7. Withdraw the tool completely and remove chips and residues from the thread and surrounding area.
  8. Inspect the thread and install the correct grease nipple without overloading the thread.
  9. Clean the tap after use and return it to its designated position in the case.

Frequently asked questions (FAQ)

What is the Tap Set for Grease Nipples intended for?
The set is designed for maintenance and repair of existing grease nipple threads. It can be used to clean and carefully re-tap internal threads affected by dirt, corrosion or minor damage.
Which thread sizes are included?
The set contains M 6 x 1.0, M 8 x 1.0, M 10 x 1.0, M 10 x 1.25, G (BSP) 1/8 x 28 and G (BSP) 1/4 x 19.
Why does the set include both metric and G (BSP) threads?
Grease fittings use different thread systems depending on the vehicle, machine, country of origin and application. Combining metric and G (BSP) sizes covers a wider range of common service situations.
Can the set be used to produce completely new threads?
The included tools are finishers and the set is primarily intended for cleaning and re-tapping existing threads. To produce a completely new internal thread, use a complete hand tap set with the required tapping stages.
What does HSS-G mean?
HSS-G denotes ground high-speed steel. The ground design supports accurate cutting edges and clean thread reworking when the tap is correctly guided and lubricated.
When is re-tapping no longer sufficient?
If thread material is torn away or insufficient sound material remains, a finisher cannot restore the original thread strength. A suitable thread repair system should then be used.
Can the individual taps be reordered?
Yes. All six taps are listed in the scope of supply with their VÖLKEL item numbers and direct links to the corresponding product pages.
Where can you find more information about VÖLKEL threading tools?
Further product, standard and application information is available in the VD 23 Threading Tools catalogue as PDF.
