I recall have seen an episode on New Yankee Workshop where Norm was building some shop furniture. As he emptied out his existing shop cabinet he had a wheel barrel full of routers! I think he said he had over 20 routers! When working on a project with a router, don’t change bits, he changes routers!
Typically follow this concept with drills out of the three cordless drills that I own, I have one that works. Augh! The other two the battery packs have died and it just isn’t worth having the battery packs rebuilt, especially when these drills are a 7.2 and 9.? volt Roybi drills.
When I am installing hardware such as drawer rails, handles, hinges, I will chuck the drill bit into the corded drill and the driver bit into the cordless. It is a pain to switch the drill bit and the driver bit out!
Unfortunately my 14.4V Skil cordless drill’s battery pack has died. This was a nice set that I had received from my in laws for Christmas a few years ago. It came with a dual battery pack. The dual battery packs worked great use one and charge the other one. In the last year the batteries started to hold less and less of a charge.
I am still able to use the cordless drill as a corded drill via an adapter that Skil made for the 12 and 14.4V cordless tools. It is a transformer / battery charger that has an adapter that plugs into the battery port on the cordless tool. It works quite well and gives me a decent amount of power. The cord length is quite nice at over twelve feet long!
I am eyeing the Dewalt 18V cordless drill. I have read and heard good things about the drill. Several of my wood working friends have them. I am thinking Christmas gift…. Hint to my wife!
