Should get my Bosch "Cobalt Twist Drill Bit Assortment with Metal
Index, 29-Piece" in a couple of days.

Stay tuned.

My understanding is that -- for the moment -- these are as good as it
gets, will still do a nice, clean job with wood, and ... will handle
those occasional, nagging titanium-drilling tasks that ... just come
up.

Split point ... SHOULD keep the bits from walking -- a major issue on
cheaper bits.

Bought them from Amazon:

If nothing else, I'm looking forward to not breaking them, and having
them stay sharp longer....
