<Nubbed? By hand? more detail please!<br>
<br>
Ouch!! I read back over my post and realized I misstated what I
meant to say.<br>
<br>
Here it is corrected with a pic of the SLOW SPIRAL, nubbed bit:<br>
<br>
1st pass 1/4" fast spiral, or whatever you bit you want to use...not
too picky<br>
2nd pass - SLOW SPIRAL nubbed run through with a hand drill. Sized
as per final target torque and block type, by test. <br>
<br>
The nubbed bit simply has the cutting edge ground off (eyeballed on
the grinder) to about a 90 deg angle at the OD of the bit's leading
edge. See pic.<br>
<br>
Just to confirm, I wrote fast spiral nubbed in my original post...I
meant to say that the 2nd pass is SLOW SPIRAL nubbed!!!<br>
<br>
I'm actually thinking of having WL Fuller regrind these so that the
1st 1" is a 1/4" non-cutting pilot step drill... but haven't had
that done that yet.<span class="HOEnZb"><font color="#888888"><br>
