Product Information

Full details

The Faithfull SDS Plus Chuck Adaptor is designed for tradespeople and DIY enthusiasts who need to utilize standard straight-shank drill bits with their SDS or SDS Plus power tools. By converting an SDS connection to a 1/2in - 20UNF thread, this adapter provides crucial versatility on the job site; however, it is essential to remember that this attachment is strictly for rotary drilling and must never be used while the hammer action is engaged.

Extended Product Information

FAQs

Can I use this for hammer drilling?

No, this adaptor must not be used in hammer mode as it could cause damage to the adaptor and the attached chuck.

Will this fit all SDS drills?

It is designed for standard SDS and SDS Plus machines.

What is the thread size?

The thread size is 1/2in - 20UNF.

Does it come with a chuck key?

No, this is an adaptor only; you must use an existing drill chuck.

Is this suitable for heavy-duty steel drilling?

While it allows for rotary drilling, SDS tools are primarily designed for masonry. Use it for light-to-medium tasks.

Troubleshooting

Chuck feels loose or wobbles during operation

Ensure the chuck is fully threaded onto the adaptor and the SDS shank is properly locked into the drill.

Adaptor is stuck in the SDS tool

Check the SDS chuck release mechanism for debris and ensure the tool is not under load while attempting to remove.

Drill bit is slipping in the attached chuck

This is likely a fault of the attached chuck itself; tighten the chuck key fully or inspect the chuck jaws for wear.

Pros and Cons

Pros

  • Increases tool versatility significantly
  • Compatible with standard 1/2in UNF drill chucks
  • Durable build quality from a reputable brand
  • Simple and quick to attach or remove

Cons

  • Cannot be used in hammer mode
  • Added length might affect balance in tight spaces
  • Not suitable for heavy-duty percussion drilling

Setup, Compatibility & Care

To set up the adaptor, insert the SDS end into your tool's bit holder as you would a standard drill bit. Thread your chosen 1/2in - 20UNF drill chuck onto the threaded end of the adaptor until it is tight and secure. To ensure longevity, keep the SDS shank clean and lightly lubricated with grease. Always verify that your power tool is switched to rotary-only mode before starting work. If the chuck becomes loose during use, detach it and ensure the threads are clear of debris before reseating. Store the adaptor in a dry, rust-free environment when not in use.
