Ordered up a new bottom tap for the Wallaby...from Travers tool. It got delivered today. Great! Took it out of the package and tried to start it in a 1/2-20 hole, and not even close to starting...I say hmmmm, my taper tap is old and hand resharpened, I'll got down the road and get a new taper and plug tap.
The local supplier was cheaper than the Travers web store, and with what turned out to be far better quality. When I got back, I put the plug tap in, no problem. I then tried the new Travers tool bottom tap...NO GO. hmmmmm Why does it look bigger than the the other two?
I read the label etched on the side of the tap. 1/2-20 H3 4fl Btm. The plastic package is marked that as well... OK....then I measure it. It measures 0.562" !
...more like 9/16-20!
I'm buying my taps local from now on if at all possible!!!
Travers is going to give me a refund....I'll let you know how that works out..
