Does anyone make a full set of drill bits where the lengths of the bits including the shanks are all the same length? I could really use a set from the very smallest in circumference to pretty large. Thanks for any help you can provide

What are you trying to accomplish? I have seen this in 6" bits. I will be interested to hear responses. Smaller diameter bits at that length are not terribly useful and large diameter bits 2" long have their place but, a full set?

You don't ordinarily see that as the smaller the diameter the weaker the cost section, so smaller diameter bits are "usually" shorter in length.

I would give WL Fuller a call and see what they can do. Here is their website:

You can find extension drills in most sizes but I have never seen them in a set.

Silver and Deming bits are that way 1/2" shank. But the diameters are just under 1/2 to about one inch diameter. designed for power drills before chucks were common. Used a drill holder instead.

I have seen aircraft extension drills in sets but the ones I have seen are of the cheaper variety, usually, the quality ones are by the piece of lots of the same size.

I am curious as to the OP's need for equal length drills, I can certainly see a need for longer than jobber length small drills but I can't envision the need for equal length but I am not the most creative thinker...

Check with aviation supply houses. Brown tool and a place called the yard. I'm not sure you will find a set

I have oak blocks that are 2” in width and 3.5” high. I want to drill equal depth holes to accommodate T-handle hex keys in both metric and imperial. It’s for a custom job and I was hoping that the T-handles would all line up equally.

sounds like a job for a drill press. move the table so that the bit is the same distance from the table and you will get equal depth holes with varying bit lengths.

I'm not sure I get that. The smallest diameter bit length might only be 2" long and I need it to drill a 3" hole.

Google "long drill bits home depot" and see what comes up.

Call Carbide Processors and they will help you out.

Here is a link of one likely to fit your needs:
http://www.carbideprocessors.com/southeast-tool/drills/brad-point-drills/straight-shank-brad-point-drills/brad-point-drills-style-20/

No trick at all to get drills with the same length for industrial use. Southeast Tool, etc all make them. They will be high quality and all the same length since they are generally used in boring machines that drill all the holes at once. Typical lengths of 5" or so. Also lots of companies make brad points in 6" length.

You can also get 6" drills very easily but they won't be brad point drills. Likely problem with them will be a short cutting length. They may be long but won't drill a deep hole. They are called Aircraft Extension bits and are available in 6, 12, 18" lengths.

what do you guys think about these? seems a little pricey but...

So the reality is you don't need them to be the same length you just need the smaller diameter bits to be longer than jobber length, correct. If a 3" hole is what you need just buy aviation bits in the small sizes and the rest can be simple, cheap, easy to find jobber length.

Cut the bottom off oak blocks, drill the holes completely through the top section, then glue the bottom back on. All the holes will be the same depth.

A fast search for "aircraft drill bit set" in amazon can bring results as this set from Grizzly (https://www.amazon.com/dp/B0000DD0PS) or this one from Peachtree (https://www.amazon.com/Perfect-Drilling-Plastic-Composite-Materials/dp/B0013EOWCE). There are other options. I hope it helps.

All the best,

Your geometry is off. hex keys get longer, on both legs, as the hex size increases. To make them even the holes will have to be deeper and deeper as the hex size increases. If the holes are drilled to the same depth the keys will stair step up in height as the size increases.

Note he is talking about T-handle drivers. Depending on the brand and set they can be all graduated, two/three different lengths or all the same length. I assume what he is working with is a set that is all the same length.
