Titanium drill bits? Huh?
A while back, I bought the TiN coated set (fractional+number+letter) for
39.95. Every one that I have used so far has been sharp and straight
(surprisingly). Of course, I looked at them in the store first.
Unfortunately, I didn't examine box/index carefully enough, because it's
missing a screw. However, the bits are serviceable. I only wish that I
could find a bargain set in machine length. The jobber length of the
larger sizes is to long for most jobs in my minimill.
Cobalt steel (of course, they only say "cobalt"), 135 degree
split points, Sounds pretty good for the price, if the drills are
Note that if the index was made by HUOT, there is a clip on the
divider extending into the side where the letter size drill bits live
which can accept a HUOT index for drills in the #61-#80 size range, and
I have just such an index clipped into mine. (I got mine as a
set from MSC several years ago for a bit over $100.00, IIRC, but those
were plain made-in-USA HSS bits -- nicely ground ones.
I'm not at all sure that what is shown is the HUOT index, as
this appears to have a latch for the index, which I don't have.
It would be interesting to check them out, if the price is good
You mean "Titanium Nitride" (TiN)? You can put a TiN coating
over drill bits made of licorice, and it won't make them drill any
better. You have to start with good metal before you coat it.

Must be a touch of senility setting in..I got my set a couple years ago
from "Northern Merch." NOT HF...but yes that is the set...lower price, but
still not worth the powder to make a small explosive device out of the
LOL, you know, I had nothing BUT Horror Fright drills in my toolbox.
After reading this group for long enough, I bought a set of U.S.-made
screw machine drills.
A few days after that purchase I was drilling 0.25-inch deep holes in
mild steel bar. I did my practice run with an HF drill, and after
getting about 0.20-inches deep, the bit was burned. Switched to the
American drill and it cut through like butter. And did so for the
next 16 holes with no problem. Bit was hotter than Hades, but didn't
burn. Even lasted through a few "oops"es.
I finally figured *that* out after 90% of those bits were laying burnt on
the shop floor. I did however purchase jobbers 1/8" titanium 12 in an
envelope and have used 1 up in two years.
Most of my bits now come from the local salvage yard, a little shapening
and they are good to go some even new in wrappers?? It's a damn wonder what
the workers in the fabrication plants here throw out, but I love 'em for
