Jaws and Springs for tap holder with ratchet (10 pieces)

• For renewing the clamping components in a tool holder with ratchet when the jaws are worn or the spring force has decreased
• For secure holding of threading tools with square shank so that the tool does not twist or slip
• For maintenance work when the holder closes unevenly or the tool can no longer be positioned cleanly with ease
• Process: manual or assisted drive depending on your tool holder and machine configuration
• Use: thread cutting, reworking threads, and cleaning threads depending on the condition of the thread

Note Clean the holder thoroughly before installation and check after assembly whether the jaws close evenly and move smoothly.

• Restores stable clamping force for reproducible work with the tool holder
• Reduces the risk of slipping and therefore protects the tool square and the holder
• All-steel design for high resistance to wear in daily use
• Targeted replacement of typical wear parts extends the service life of the existing holder
• Supports smooth running because the tool sits more precisely and force transmission becomes more even

• If the holder geometry is damaged or the guides in the holder are worn out, replacing the parts alone may not fully restore functionality
• For permanently high torque in series processes, a machine concept designed for that purpose is usually more suitable than a hand ratchet

1. Remove the tool from the holder and place the holder so that small parts can be safely caught.
2. Open the holder area and visually note the existing installation position of the jaws and spring.
3. Remove the jaws and spring, making sure that no parts tilt or are damaged.
4. Clean the holder, guides, and contact surfaces and completely remove abrasion and adhering chips.
5. Insert the spring and check that it sits without stress and does not change position when you move the jaws.
6. Insert the jaws and check whether both sides are guided evenly and close cleanly.
7. Open and close several times, paying attention to even running and symmetrical contact.
8. Insert the tool, clamp it, and verify the secure fit with a short functional test.

How can you tell that replacement makes sense?
If the tool still has play despite being firmly clamped, twists slightly, or yields under load, the jaws or spring are often the cause. Uneven closing of the holder or a noticeably soft clamping point also indicates wear.

Does this unit fit every tool holder with ratchet?
It is intended for VÖLKEL tool holders with ratchet in size No. 2 / 20. Check the size marking on your holder so that the installation position and clamping geometry match.

Why does the spring influence the clamping so strongly?
The spring provides defined contact pressure and a stable starting position of the jaws. If the spring becomes fatigued, the jaws no longer close evenly and the clamping force builds up less reproducibly.

Can poor clamping damage the threading tool?
Yes, if the tool slips or tilts, localized peak loads occur on the square shank and the clamping surfaces. This can cause both the holder and the inserted tool to wear prematurely.

How should you check the holder after replacement?
Open and close the holder several times and check whether the jaws move synchronously. After clamping, the tool should sit without noticeable play and should be controllable when positioned.

What maintenance helps increase the service life of the new parts?
Keep the holder clean, remove abrasion and chips after use, and store the holder in a dry place. If you change tools frequently, it is worth briefly inspecting the clamping surfaces before clamping the tool.
