Where To Buy 3/4" Contersink Tomorrow
I'm going to be really pressed for time so grid searching is out of the question. I need a 3/4" model for plastic and aluminum. With a 1/4" or 3/8" shank Has anyone of you actually bought one in...

I've got a Ryobi 8 volt variable speed 3/8" lithium drill that manages to give me superb control ability. The type of plastic the Rigid box is made of likes to leave streamers and long buzz whiskers on the other side of a hole. I will also use the countersink on holes drilled in Lexan for this project and then around the circumference of a hole for a 120mm muffin fan.
Yes I looked at a quality single Silver & Deming 7/8" drill but the thirty dollars was a turn-off as was the 1/2" shank.
The 1/4" thick lexan plate is going to be tapped for 1/4" x 28 bolts.
I am using external tooth lockwashers on 1/2" switches and the 11 position rotary switch uses an 1/8" anti rotation tang which means drilling an 1/8" hole.
This is a true "Buck's Up" battery charger and the fit and finish is going to reflect that fact.
One feature - Twist the timer to start the charger. A built in 10 second delay timer allows the set voltage to be displayed for that long before a solenoid engages power out through the cables. Ten seconds is long enough to reset the 11 position voltage selection switch if for whatever reason the first choice is in doubt. All eleven settings are purpose-tasked not just ambiguous voltage settings. A 12 hour timer allows for instance a proxy voltage that mimics alternator setpoint voltage. There is a "tweaker" multi turn potentiometer that will precise tune in 16.0 volts for equalization, and 14.4 volts for AGM absorbsion charging. The theoretical 1.8 kAh timed capacity allows for a number of 8-D AGM batteries to be charged in parallel.
