Check this out – an 18-inch core drill bit extension from Advanta, model AT-CBEXT18A9.
It's got a 1-1/4"-7 male thread on one end and a 1-1/4"-7 female on the other, so you can reach deeper holes without breakin' a sweat.
Brand new, unused, in original packaging (maybe a plain box or bag, but that's how Advanta ships).
Perfect for concrete, masonry, or tile work when you need extra length.
Built tough, this extension handles the torque and vibration.
Just a heads-up – California Prop 65 warning applies 'cause it contains lead compounds, so don't eat it, alright?
But for drillin', it's golden.
