Introduction: Easy Mini Drill Press

I was looking for an easy mini drill press for drilling PCB for example. So i went to the web to find that.

I didn't found exactly what i wanted in DIY projects or shop so i built this :)

This press is strong, accurate and not expensive !

Step 1: Materials

Tools needed:

  • Drill
  • Jigsaw

  • Ruler and pencil

Materials (25$ if you already have the mini drill):

  • MDF Wood (thickness 1.8cm 0.708") 5$

  • Drawer slides (i used 20cm 7.87" one) 7$

  • Mini drill like a Dremel or another one like mine 35$
  • Rubber band or spring 1$

  • Wood lever 2$
  • Hose clamps (mine were Ø5cm-17.5cm Ø1.97"-6.89") 5$

  • Wood glue 3$
  • Screw 2$

Step 2: Cut Your MDF Parts

As you can see on the picture, you need two parts for the left and right side, one part for the bottom and two parts for holding the drawers slides.

  • Refer to the picture to have the dimensions and with the ruler and pencil, draw the parts.
  • Now, with the Jigsaw you can cut the MDF.

Step 3: Attach the Mini Drill

  • In one of the 3.94" x 9.45" (10cm x 24cm) part, you have to drill 4 long holes to the hose clamps.
  • Put your mini drill on the MDF part and center it well. With your pencil, draw the holes and then drill them like on the picture. (I can't tell you the dimensions as it reports to your mini drill form)
  • Now that you have 4 holes in the MDF part, attach the mini drill with the hose clamps. Be sure that the hose clamps are flat on the reverse side.

Step 4: Time to Set the Parts Together !

  • Lay down the left and right side and align the back side (the other 3.94" x 9.45" part) correctly.
  • Once it's done, drill 4 holes for the screw (if you don't do that, the wood will break) and take a drawer slide for the spacing.
  • Now, put some wood glue, put the back part, the drawers slides and screw all together.

Step 5: Attach the Mini Drill to the Drawer Slides

It's the "hard" part.

  • You have to make 4 mark on the back of the mini drill part and to drill 4 small holes. You need those holes for the 4 mini screw to tie the drawer slides to the wood. Be sure to make a good alignment.
  • Once it's done, tight the 2 top screws.
  • Then, slide back and tight the 2 botom screws.

YATAA ! You have your mini drill press body and it slide well !

(Sorry for the yataa, i start again Heroes tv serie :D)

Step 6: Screw the Bottom Part

  • Now, take the bottom MDF part and align + center the body on a side with care. Draw lines with your pencil to mark the "feet".
  • Drill 4 holes in the bottom part where the feet are.
  • Use the tool (sorry, don't know his name) to hide the head of the screw in the wood.
  • Now, put some glue and screw the bottom part in the feet.

Step 7: Finishing Off

Now, you are altmost done.

To finish, we need 2 more additions: a lever and a mecanism to pull up the mini drill !

  • For the lever i used a wood stick like a spoon handle.
  • And to pull up the mini drill, waiting to receive some spring, i used some rubber bands from an old air chamber.

Here we go, now you have your nice & practical mini drill press DIY :)

Todo in the future list:

Add LED lights (i'm working on it)

Add a small vice to hold the PCB when drilling

The drawer sliders I got were slightly more work to use, but I think it turned out pretty well! On the right side I had to place some acrylic over the slider to prevent it from escaping outward off the track.

I used the $9 dremel from Harbor Freight Tools. It should hold me through a few basic PCBs.

Thanks for the great idea Shoyun!


I used the very cheap dremel from Harbor Freight Tools.

Hi Shoyun,

I am sorry to say just after this instructable came up one of our low cost shops (LIDL) had a special on of a aluminium drill press and as it was so cheap £20 I bought one and has been operating quite well except for the height adjustment lock system which striped and has been replaced with a stainless steel 5 mm hex head screw and nut which has been ok for the last 6 months I still yet have to try and fit two lasers to it but I still think this was a great instructable. regards Poppy Ann.

Hi Again,

After receiving this comment it gave me a push in the laser line mod and I just ordered two laser line modules to give it a try on my drill so if it works out ok I will post it on here for others to use.

regards Poppy Ann.

I wonder if its possible to add a laser pointer site to this. Most of the broken bits in my class occured when the bit missed the target and the person tried to ajust it. Of course, one would also have to narrow the beam of the laser pointer to accomidate the bit size for pcb

author
Shoyun made it!(author)2014-09-15

Hi !

For sure it's possible. You can buy a laser module (on ebay for example) and power it with a battery. For the position i think it would be better to put it on the left or right side, in a part which don't move, then you just have to calibrate.

Poppy+Ann made it!(author)2014-09-16

the problem with trying to fit a laser pointer is that it would need adjusting each time you tried to use it on different height materials, i think that if you used two of the lasers that give out a straight line and set them at 90 deg from each other would work ok even with different height materials.

author
mahela007 made it!(author)2015-09-13

could you explain in a little more detail how to mount the lasers ? I can't quite picture what you have explained

author
alcurb made it!(author)2014-09-17

I imagine what you described with one line laser mounted under the drill and one mounted up high on the base or vertical structure pointing from the left or right side.

author
Poppy+Ann made it!(author)2014-09-17

yes that is what i was thinking of then you always get the right center without moving the pointer every time you try to drill a different height.

That is just plain brilliant!

author
Shoyun made it!(author)2014-09-16

I was thinking about a laser holder which would be easily adjustable if you change material heigh, like hard iron wire.

Good idea the 2 lasers anyway !

schaude made it!(author)2014-10-16

nice instructable, i think i'll make it! adding lasers seems to be a good idea, too. i'd better use two line focused lasers in an 90° angle horizontally and 45° angle vertically. painting a line instead of a dot with this there'll always be a red cross under the drill bit not depending in the size of the material being drilled. they cost around 2 $ each (i.e. at dx). one could be hotglued (easy & fast fixing and tuning) behind the motor between the sides; the other one could be on one side in the moving part or would need a special wooden holder on the side of the machine.

Instead of using drawer slides, I just wrapped angle iron around the sides.

Nice cheap drill press. Very clever.

I'm thinking of building one, but for a full-size pistol-grip battery-powered hand drill and make it so that the drill can be easily inserted and removed. That would mean departing from the hose clamp method, but I don't quite know how to approach it.

author
Rolf+G made it!(author)2014-09-17

The alternative hose clamp by the author seems OK but maybe you can try doing this cheap and easy one. It can do the " easily inserted and removed" you want.

It can be made of wood or aluminum depending on your choice. This is only my idea. I hope you will like it.

Cool. Are those hard to make? My drill has an irregular cross section.

author
Rolf+G made it!(author)2014-09-17

Oh I see... In this case you can make a 2-piece wood clamp which is not hard to make. Since you will not use it in heavy load. But in case, you can put stopper at the top of the drill for reinforcement.

To create a suitable cross section shape of your drill, I suggest that you make a pattern first out of hard paper or carton.

Use a Jig saw in cutting the wood to shape.

It is also better to glue a rubber into inner layer of the clamp (salvaged from tire tube) to avoid slip, for better crimp and scratch free.

I used this technique not in this project but clamping a galvanized tube.

The hose clamps i used are not fast enough for your project, and they will break (where there is the screw thread) if you set/unset many times.

I found those one on the web, like for bikes, and they are quick and easy to use ! Moreover, they won't break easily ! (quick hose clamp in google to find what you are looking for)
