It looked like this would be a good fit to hold the Milwaukee 4 volt cordless screwdriver I recently bought. Turns out, there were elasto-straps that held the extra battery, charger and screwdriver, with a pantload of room to spare. How much will it hold? Hmmm.... And it looks as if it will hold up to any abuse I'll dish out.
I use this tool bag for my Milwaukee accessories I have. It will hold 3 accessory cases like drill bits, spade bits, or driver bit sets. Grab one bag and have all the drill accessories I need in one bag.
