Pulling baskets are a royal PITA....someone always loses the "right one", the loose strands stab me, etc.
I like the rip-cord idea...wish you mentioned it 2 weeks ago when we did our 500KCM pulls (12 runs x 4 wires x 200')...that would have saved some time.
We usulally wrap the head w/rags, back tape and tape with duct tape. Sure the head comes apart quickly - but that rip-cord would be even faster!
The hole saw "tip" is like this...load the drill up with your hole saw, arbor and pilot(just like usual). Then slip the fender washer over the pilot - you will have the pilto extending through the fender, and the fender is blocking the hole saws teeth. After the pilot punched through the material, remove the fender and continue drilling with the hole saw. This is a GREAT tip (I do it every time) because sometimes the holesaw (w/o fender) will bind on the material. This binding action is accompanied by the drill's twisting and attempting to break your wrist.
