If you are going to recommend a HF product, you should include the
item number, including the appropriate 3 digit/letter sale or calalog
code :-) HF probably has 20 different countersink bit sets and each
probably has 20 different final 3 digits in it part number with 20
different prices...and hey, I could use a good countersink bit set!
O.K., it's item #00550, "22pc. high speed steel bits" including wooden
storage box, 7 pilot bits, 7 countersinks, 7 depth collars, and one
allen wrench. Mysteriously there is an identical set at the store for
$9 something that is a "low speed" set. As with most good bargains
there is a slight hitch - you will probably want to replace the tapered
bits, which tend to burn up and "suck down" into the wood, with a cheap
set of regular twist drills. I never found those twist bits to be
worth the advantage of having a tapered hole.
But the countersinks themselves seem to be staying sharp, which is the
