B & D demolition rotary hammer bit interchange

[KMinAF]

I have a mature Black & Decker rotary / demolition hammer that I would like to get a spade bit for but an unable to find a similar shank style from other manufacturers. Does anyone know of a brand that will interchange with what I have?
The hex portion is 1/2" thick and 1 1/2" long. Thanks

I have the same hammer and the same problem. I have the book and it says the hex part is optional so if you find a suitable round shank took it might work. The shank length should be two inches where it goes into the hammer (going by memory, can confirm).

Hmm, missed this the first time thru. What dimensions across flats on the hex?

These guys may get you close, or tell you it’s a lost cause. You don’t give your model number, so go to the top and start from Chisel Lookup by Hammer

This one fits my Bosch 11202. 1-1/8” hex shank. As yh noted the hex isn’t required to hammer, but will keep the bit from rotating.

I have a DeWalt that is 3/4 hex that looks a lot like that bit, and I bought extra bits on Ebay and Amazon as I remember. Heavy tool but it works great. The ground rod driver works faster than you can climb down a ladder trying to keep up with it. The spade bit digs this clay/quartz mix we have around here, a shovel doesn't even touch it.
