Product Information

Full details

The Halder SIMPLEX Replacement Head (3203.051) is a professional-grade TPE-mid impact insert designed for users who require a medium-hard striking surface that leaves no residual marks. It is ideal for maintenance, repair, and assembly tasks where surface protection is paramount, though it is specifically engineered for light to moderate striking applications rather than heavy-duty demolition.

FAQs

What does 90 Shore A mean?

Shore A is a scale used to measure the hardness of flexible mold rubbers and elastomers; 90 indicates a medium-hard rating suitable for controlled impact.

Will this head fit all Halder mallets?

It is specifically designed for the SIMPLEX range; please confirm your housing size to ensure compatibility with the 50mm diameter standard.

Can I use this for outdoor stone work?

While durable, this insert is intended for clean-working assembly and repair; abrasive stone surfaces may degrade the TPE material quickly.

Does this insert come with the mallet handle?

No, this is a replacement head only. The handle and housing must be purchased separately or used from your existing tool.

How do I know when to replace the insert?

You should replace the insert once the striking surface becomes excessively pitted, cracked, or deformed, which can compromise the safety and accuracy of your strikes.

Troubleshooting

Insert feels loose during use

Check that the threaded connection is fully tightened or that the insert is firmly seated in the housing collar.

Surface marks appearing on workpiece

Clean the face of the insert with a damp cloth to remove accumulated dirt or grease from previous tasks.

Pros and Cons

Pros

  • Leaves no black abrasion marks on surfaces
  • Balanced weight (71g) ensures accurate striking
  • Medium-hard density is versatile for diverse tasks
  • Easy to install on existing SIMPLEX mallet housings
  • Durable thermoplastic elastomer construction

Cons

  • Not suitable for extremely heavy-duty industrial demolition
  • Requires an existing compatible SIMPLEX mallet housing
  • Medium hardness may be too soft for driving large metal spikes

Setup, Compatibility & Care

To install the 3203.051, simply unscrew the existing insert from the SIMPLEX mallet housing and thread or press the new head into place depending on your specific model configuration. Always ensure the housing is clear of debris before installation for a secure fit.

This insert is designed for compatibility with the wider Halder SIMPLEX mallet range. To maintain the life of the insert, avoid striking sharp metal edges or high-heat surfaces, which can prematurely wear the elastomer material. Store the mallet in a dry place to maintain the material integrity of the plastic components.
