Team Associated Factory Team Tool Handle (Without Tips)
Dimensions: 113.8mm Long x 23.3mm Outer Diameter
The chuck secures the standard size 1/4" hex shank bits in place with a fairly strong magnet.
Inner compartment can store up to seven 70mm long standard 1/4" hex shank bits.
The plastic bit holder butt is secured to the handle by an O-ring. The handle has an inner recess where the O-ring sits. This design holds plastic bit holder in place without concern of coming loose, but it also makes the bit holder challenging to remove. I would prefer a threaded design.
