Gor a Tapcon condrive 500 on Ebay for 9.99 (plus approx same shipping, or you can bundle) took them to a machinist friend and adapted it to a quick-connect 1/4 inch (it comes with a 5/16 inch hex), put a slightly shortened long standard drill bit (with flat spot) and it works great in the makita 12 vt.

The speed of the impact is great for drilling.

If there is a condrive available that fits the 1/4 quick connect I’m not aware of it.
