Drill Chucks & Adaptors

Drill chucks and adaptors let you switch between bit types and expand your drill’s capability. Whether you need to convert SDS to standard, extend reach, or upgrade to keyless, these accessories are essential for maximum tool versatility on-site or in the workshop.

What Are Drill Chucks & Adaptors Used For?

These accessories help with tool compatibility and grip strength:

  • Chuck Replacement – Swap worn or keyed chucks for keyless alternatives
  • SDS Conversion – Fit standard drill bits into SDS+ hammer drills
  • Hex to Round – Use twist drill bits in impact drivers via hex-shank adaptors
  • Bit Extension – Add reach or offset to drills for awkward access jobs

Used By:

  • Electricians and plumbers using SDS drills on mixed fixings
  • Joiners needing to switch between pilot and clearance drills
  • Tradespeople upgrading older keyed drills to fast-release keyless

Choosing a Chuck or Drill Adaptor

Focus on compatibility, chuck type and rated torque:

1. SDS Compatibility

To convert SDS+ to standard, choose an adaptor with internal jaws and hammer-safe shank.

2. Chuck Type

Keyless chucks offer fast bit swaps. Keyed chucks deliver more torque grip — great for metal drilling.

3. Tool Fitment

Check thread size (usually 1/2" or 3/8") and if the adaptor matches your driver or rotary drill model.

Drill Chuck & Adaptor FAQs

Can I use standard bits in an SDS drill?

Yes — with an SDS adaptor chuck. These fit into the SDS mechanism and allow standard round-shank bits to be used safely.

What’s the difference between keyed and keyless chucks?

Keyed chucks use a gear-driven key for maximum grip. Keyless chucks twist by hand and are faster but may slip under high torque.

Do chuck adaptors fit impact drivers?

Only if they’re hex-shanked and impact rated. Avoid using twist bit chucks in impact tools unless specified.

How do I know which chuck fits my drill?

Check the thread mount size (often 1/2" x 20 UNF) or your drill manual. Match chuck and adaptor to power tool spec for safe use.
