Greetings all; It appears that its well nigh impossible to get a firm enough grip on a tap shank, and on the smooth, unkeyed TTS ER-32 holder, to reliably lock a tap for rigid tapping. I've considered buying ER-32's with square sockets, but for >8mm taps, the TTS adapter/holder will spin in the R8.
So the only way is to buy R8's with square bores, which, given the length of the square on the end of the tap, seems to be a better way, for some definition of "better". In my search for such beasts, I find several Chinese makers, unfortunately with minimum orders of 10 each usually attached. There are none to be found on ebay, and apparently the only US seller must be gold plating them as they're running from $15 each on up. If I was to buy 10 of each metric size, 3mm to 14mm and some come in .5mm sizes, I'd have several thou $ tied up. Making boxes to hold one of each size could be done, making a kit of around 20 pieces. At say $175 a kit, how many could I resell to those of you in the US in an effort to at least break even & leave me with a kit? For those of you lucky enough to have some of these, are they truly an answer for this problem?, or something that works only if your chew of Kentucky Twist is just so. I am not personally impressed with something that grips only the square of a taps butt end, but it would for me, be better than at present. Thanks. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
