The Ultimate Drill Improvement Kit




This instructable will show how to make The ultimate drill improvement kit from 3D printed parts and standard parts.

Clamped on a standard drill, this tool will help to:

  • drill perpendicular
  • drill at the right depth
  • drill on cylindrical parts
  • and also to do clean drilling

This design is for a standard 43mm drill attachment, it can be updated for other type of drill (STP files are attached).

This instructable is in the Build a tool contest, thank you to vote for him if you find it useful.

Step 1: Parts and Tools

Parts required:

  • 2 steel tube, internal diameter 8mm, length 30mm
  • 2 springs diameter 10 x 55mm
  • 4 self locking nut M8
  • 2 threaded rods M8 length 165mm
  • 4 M6 nuts
  • 4 M6 bolts

Tools required:

  • 3D printer
  • jigsaw
  • file/sandpaper
  • glue
  • flat spanner

Step 2: Prepare the Parts

Steel tubes

Cut to 30mm length with a jigsaw and finish with file/sand paper.

Threaded rods

  1. Cut to165mm length with a jigsaw.
  2. Put 2 M8 nut at 8mm, then file 2 flats until it matches with a 5.5mm spanner.
  3. Finish with file/sand paper.

Parts printing

5 printed parts are needed:

  • Baseplate
  • Drill attachment
  • Extension, required for drill bit longer than 100mm
  • Tube adaptor, required to drill straight across tube
  • Vacuum adaptor

I used the following parameters :

  • Layer 0,2mm
  • Honeycomb infill 30 %
  • Support is required for drill attachment, vacuum adaptor and tube adaptor

Step 3: Assembly

  1. Glue a M6 nut in the drill attachment slot
  2. Glue the threaded rod on the baseplate and insert the steel tubes
  3. Glue the steel tubes in the drill attachment
  4. Put a M8 nut on each threaded rod
  5. Insert the rod in the attachment, then add M8 nuts and springs
  6. Tight until the height between baseplate and attachment reach 43mm
  7. Glue a M6 nut in the extension slot
  8. For drill bit longer than 100mm, the extension have to be used. In this case fasten the extension on the drill attachment with 2 M6 bolts
  9. install the tool on the 43mm attachment of the drill and tight the M6 bolt. The pictures show the tool with and without the extension
  10. Clip the vacuum adaptor on the baseplate
  11. Clip the tube adaptor below the base plate

Step 4: Let's Drill

The depth can be set with a 13mm spanner (hold the rod with a 5.5mm spanner), in this case 35mm.

Both M8 nuts must be at the same height.

Hold the baseplate with 2 fingers then push on the drill.

For accurate countersink, fine tune the M8 nut: a 1/4 turn is about 0.3mm (pitch is 1.25mm).

Drilling across tubes is possible up to 30mm diameter (stroke of the tool is limited to 35mm).

And thanks to the vacuum adaptor, you can now drill a brick wall without any dust.

    I just emailed a Maker in a town near to me. As I was typing out the message I was thinking of your design and could not wonder if you will be making these to sell. I see no reason why if the Press is working well for you why you shouldn't be able to sell them ( also slap a patent on your design ). The Files you provide are appreciated but for those of us that do not know anything about 3-D printing just that it is an amazing tool and have to find some one who can do the printing your offering to make to sell would be a good thing.

    LOL now I have to find a store with a 3D printer. If not I have to figure a way to translate your design into another medium. Great design, I do not see how this will not work. Thank you for sharing :)

    i am printing the parts right now, everything has been printing perfectly as far. i will return for a verdict, when i have tested the rig. i love the idea, just hoping that it will be sturdy enough.

    Happy you want to test it.

    One important point when you print the main part is to ensure a good fitting on the diameter 43mm of the drill. You can measure the exact diameter and adapt it on the 3D file (use the STP file), take in account also that your 3D printer will print a smaller hole.

    It seems my explanations were not clear enough !

    It's a kind of portable drill press to use on any flat surface. The drilling depth can be adjusted.You can also add a vacuum cleaner with the adaptor.

    I will add it soon in Thingiverse. The files are already available in the step 2.
