Looking for a drill

[gcode]

I'm looking for a thru coolant 1/2 carbide drill
15X is too short and 20x is longer than necessary
does anyone know of a manufacturer than makes a 17 or 18X drill
the material is a cast carbon steel
It's a through hole 8.8" long

Guhring has one with a max drilling depth of 9.014"
They label it as 15xD but all mfg's have different lengths for their ratios I've found.

Walter has a couple they classify as 16xD with a 9.37" drill depth

Silly Q ... It looks like they don't make them that big
I've got quotes on both the Guhring and the Titex

Guhring  $607

Titex --- gold plated and sprinkled in diamond dust    $1070

either of these can work .. actual drill depth is 8.8 +.100 breakout

Mitsubishi makes real nice drills too
but their .5 x 15X  is  $515 but only has a 7.55 drill depth

So far I'm thinking the Gurhing is the winner

I haven't had any luck finding other manufacturers

Nachii makes nice drills and a lot of our old tool list call them
out, but their web page and cataloge is so bad I'm gave up looking

Thanks for the help

Guhring  $607

MSC has it listed at $542 so if you get the 15% discount it will be even cheaper.

FYI if you look at OSG, beware that they don't give you max drill depth, just overall flute length which sucks because you never want to drill to the flute washout.
Their 15xd has 230mm flute length.

The OSG drill had a nice list price too $527
I've ordered the the Guhring
and will hold it in this

When reading that I thought "someone's hacked G's login"!

Definitely a JB hack, can't drill a hole, doesn't know the brands....

Pretty sure the ONLY reason I know of them was because I worked at a Japanese company BITD.
