Greenlee 50027069 – Frequently Asked Questions

1) Will the Greenlee 50027069 bit extension fit a standard cordless drill or impact driver chuck?
It uses a 1/4 inch hex shank, so it drops into any 1/4 inch hex quick-change holder on an impact driver, and it also chucks up fine in a standard three-jaw drill chuck. That is the common hex size for electricians running auger and self-feed bits through studs and joists.
2) What size bit shank does the Greenlee 50027069 extension accept on the business end?
The bit end takes a 1/4 inch shank, matching what goes into the driver. The head measures 9/16 inch in diameter, so the extension itself passes through any hole your bit has already opened up without hanging up on the edges.
3) How much extra reach does the Greenlee 50027069 bit extension give me for boring through studs?
It is a 14.050 inch long extension, so it adds roughly a foot of reach past your bit. That is enough to bore through a stud bay from one side, or to reach a joist from below without repositioning a ladder. It is made for boring deeper into wood than a standard bit alone allows.
4) Is the Greenlee 50027069 meant for wood boring or can I use it for metal drilling?
It is specified for boring deeper into wood, which is the typical electrician use case: running romex or conduit through framing, joists, and top plates. Pair it with an auger or ship auger carrying a 1/4 inch hex shank.
5) Does the Greenlee 50027069 bit extension come with a bit included?
No. It is the extension only, sold in a pop-style retail pack under part number 50027069. You supply the auger or spade bit, which must have a 1/4 inch hex shank to seat in the holder.
6) Can the Greenlee 50027069 extension follow the bit through the hole it just drilled?
Yes, provided the bit cuts wider than 9/16 inch. That is the head diameter of the extension, so any auger or spade bit over that size leaves clearance for the extension body to pass through the framing behind it.
