Thanks Splinter... I really appreciate that.  The drive for my purchases is beyond mere mortal comprehension, consequently I finish up with many good and a helluva lottta bad stuff. 
I review from convenience point of view rather than regularity of use vs shekel outlay... I don't mind owning up to my mistakes... after all it wasn't my fault that I was born.

After all the BS, GW the b'all countersinks are these,

with the tapered bits... if you just want one pick a screw gauage and only use them... before I migrate my review from LJ over here, you can sneak a preview and drift off to dream about unicorns kissing frogs

If your first cut is too short... Take the second cut from the longer end... LBD
