7.6: What types of drill chucks work with Chuck Extensions?

Chuck Extensions work with most common keyed and keyless drill chucks on commercial drills that can accept 0.5” diameter drill bits. Here is a general list of drill type and drill chuck compatibility conditions for Chuck Extensions:

1. The drill chuck has a round, metallic, flat face of greater than or equal to 0.65" diameter
2. The drill chuck has a bit hole of less than or equal to 0.56" diameter and larger than or equal to 0.414"
3. The drill has a maximum RPM equal to or less than 2500 RPM

Here is a general list of Chuck Extension incompatible drill types and drill chucks:

1. Chuck Extensions are incompatible with drill chucks that have smaller diameter faces, such as those that require use of a Standard Chuck Guide. Do not use Chuck Extensions with drill chucks that have smaller diameter faces and/or require use of a Standard Chuck Guide.
2. Chuck Extensions are incompatible with Hex Shank drill chucks. Do NOT attempt to use Chuck Extensions with Hex Shank drill chucks.
3. Chuck Extensions are incompatible with pneumatic drills due to the fast rotational acceleration of pneumatic drills and or the smaller diameter faces that are typically incorporated onto pneumatic drills. Do NOT use or attempt to use Chuck Extensions with pneumatic drills.
