What type of application (drilling method) are you trying to achieve?
There are bit extenders widley available.
A little more info on your  needs, like depth of hole and material to be drilled through would help.

Mike

I presume you are seeking to drill flute blanks. 

Bob Bowers in his book on spirals shows an adaption of aircraft bits (surplus) to compressed air for drilling barley twist spiral blanks.  He shows both open bines and also inserting contrasting rods in the holes.

Boeing Surplus had some really long ones during a visit a few years back.

New bits are a frightful cost, but surplus ones were $10-$25.

Ken,
          I drill the flute blanks with a gun drill .....expensive. It  has a hole for compress air the length of the gun drill . My setup is not perfect and sometimes i'll get a little drift.not much. I would need these bits for the pilot holes.The short ones I use are dead on for their depth.I havealways been able to use what I drilled.I think I lost only one flute in all these yrs....So if I could find mainly the 7/8" that would help a lot but be good to have the 3/4" and 1" also.Just looking for best deal...If I had them 8" long that would be great ...I wonder what other kind of bit could be used.I cant use an extension because the bit has to go through a guide bushing the size of the bit. Thanks for any help!!

actually they have the deming bits too.....just looked

and if you need them longer a decent welder could add an extension as long as you need/want...I have done that in the past to put pegs in railroad tie walls...3/4'' 3 feet long...priceless!

There are many different types of bits that can work.
What type of bit are you looking for? (cutting tip, flute, etc)
What is your price range?

Ed, I was sort of  wanting extended length Silver and Deming bits. I've heard Boeing Surplus has used bits but my searches so far havent yielded much. Im just looking for the best deal right now. I use the 7/8" bits the most so I could buy the 7/8" one and use it like a pilot for the 1".The 3/4" I use but not nearly as much. I (I am a flute maker and bore my flutes with a gundrill.My setup works very well.I start drilling with the standard length silver and deming bits then go to the gun drill/...My setup works great but very occasionally one will be off a little....The part I drill at the end with the s and d bits are dead on) Thanks for any links or searches you do.

Do you need reduced shank to 1/2"?

Mike,

If I remember correctly the S&D bits are defined as 1/2 inch shank and 6 inches effective length.

There are 7/8 inch bits up to 12 inch overall with 9 inches of flute, but not reduced shank.

Such a bit could be ground down to fit a larger chuck such a 3/4 or 5/8

Ken thats what Ive found too...like these  (I dont see how long though...probably whatever a general purpose bits length is)

These are similar to what I have already.

Im sort of rethinking my setup..Basically I have a bearing box...that goes near tailstock...Has 1 1/2" 4 bolt flange bearing on side nearest headstock.Backside (near tailstock has the guide bushing in it.The guide bushing doesnt really do much..Ive seen some w/o it.I think I can remove it and would get more out of drill bit I have now.(with the guide bushing in the board on back it limits the drill some)The bearing really keeps it in line and the tailstock with drill bit is accurate enough for this.Ill see if I have a pic and may post it.I know this doesnt make a lot of sense right now lol.Thanks for all the help.

This is why I asked about the need for a reduce shank.
I would not grind down a drill bit shank, more work and more expense for a consumable item.
IMO it would be much easier to use a collet chuck in the tailstock to hold the bit. (much less expensive than a 1" Jacobs chuck)

These two statements are a bit confusing. Are you referring to the same thing or is there a bearing and a bushing?
I understand your "general" method but your particular setup really requires a photo before anyone can offer anymore help without guessing.

Mike ---

Take a look at your setup and see if a taper shank bit might work.  A mt2  bit is about $12 and shipping (without checking moq)  with an overall length of about 10 inches. 

The advantage is that there is a huge range of sizes, and you do not need a jacobs chuck. 

From your description, it is likely to work.

Ed I have a boring "box"...On the front of it is a 1 1/2" 4 bolt flange bearing On the back of the "box" is a guide bushing to line up the gundrill but really the drill I use to drill the pilot hole (the ones I am looking for ) pretty well lines everything up.The gundril's geometry on the bit is set up (according to what Ive read ) to help keep the bit on center once it starts...I would like to go a little a little deeper with the pilot hole.I am drilling a 36" blank usually.(I go 1/2 way then flip the blank and go the other 1/2 way.....Its looking like the way Ken is talking about ....a drill bit for MT2 might be the way to go.

I was looking at

These are nothing fancy -  but handy.   Note I did not see 7/8 but 57/64 is very close

These folks sell long boy 12 inch bits also but the price goes way up fast.

by the way, the drill doctor does not care what the shank is like but mine does not go to 7/8 inch (have done 5/8 and 11/16 though)

Half way would be 18" if my math is correct Roll Eyes Undecided
So I'm guessing this was a typo?

Mike Turner wrote on Apr 4th, 2017 at 6:44pm:

Or are you looking for half way of 18 inches?

MT bits are certainly an option but finding a 7/8' MT2 bit with 10" - 12" of cutting length will most likely cost more than a standard bit.
Machining costs money, reduced shank (silver & Deming) = money, Morse taper = money, extra length = money.
This is why I suggested something like Multimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to Login or Register
This can be used in a collet chuck (a useful tool IMO) and won't break the bank.
The bits that Ken linked to are a good price but with a flute length of 6-1/8", what are you gaining over what you currently have?

Im not looking for 18". 10" would be sufficient. The bits I have have 6" but I lose a little of that by not being able to go past the guide bushing on the back of the box near the tailstock plus the blank cant be all the way up to the bushing on the inside of the box because chips have to be removed..I have a shop vac hooked to side of box pulling those out . (A gundril has a hole going through the bit's entire length for compressed air to blow chips out or it would bog down.) It works very good just once in a while it does drift a little but what I drill with the drills for the pilot hole is really accurate....Ive only lost one flute blank in the past.I would drill the pilot hole on both ends .I know it s probable hard to picture all this...Weekend I ll try to get a pic posted.
....I do like those bits and it takes the chuck out of the picture but I dont gain any length ..now if they were 10" that would be good

Mike, this is all well and good.
I understand your process and how a gun drill works. Your comments about length of piece and drill bit have been a bit confusing.

You need to determine EXACTLY what length dill bit you need. (or at least the minimum length)
This means taking into account all of the bushings, bearings, chucks and fixtures the bit will encounter.
Add that length to
The depth of the pilot hole you want to dill.
Effective length and overall length are very different and probably about 3" apart from your description

You can get them in that length, for about $100 per bit

12 inch morse taper 7/8 bit with 8 inches flute.  You loose a couple of inches into the taper so effective length is less.

They also come in longer formats at higher prices.

Long bits are a challenge on my lathe because the extension of the tail stock is limited to about 4 inches.   I can leave the lock loose and push the tailstock, but there is no pretext of fine control.

Ed I think Ill pass on the $100 bit. I saw some of those.

Ken my lathe is the same way.Go so fart and have to unlock tailstock and push forward.

I think if I redesign  or even remove the board on the back with the guide bushing I can get almost all the length out of my current drill bits minus whats in the chuck ....Box would be open and make a little more mess but its wood working.

Thanks guys for all your links, suggestions etc!!!!!!!!
