This equipment is safety category 3:

  • Mandatory, in person, instructions.
  • Make sure you read the Wiki before asking.

This equipment is Noise Category 2:
Can be used at all hours, but in moderation.
Be considerate; if you feel you need to wear ear protection,
then only use the tool between 07:00 and 19:00.

Beware that unlike the small and lighter version in the woodarea
- this machine will NOT stop if something jams or gets stuck -
but typically ruin either the drill, your work or,
if you are foolish enough to hold it by hand, your hand or other nearby body parts.
For this reason - the use of (strong) gloves is forbidden.
And you probably want to use the machine clamps or the Opspanset / T-Slot Clamping Kit.

Boor-kolom, Drill press, Pillar drill

with adjustable speed (the small wheel on the left of the machine). This is the heavier, 3-phase (Krachtstroom), version in the metal shop; there is a lighter version in the woodarea.

Cutting wood in the metal area is fine. Cutting metal in the wood area is frowned upon. If you do so - de-grease the machine/plateau post use !

  1. Handle for up/down of the head. Clockwise for down; Counterclockwise for up. Do not forget to (un)tighten handle 9.
  2. Handle for the speed.
  3. Hole through which you can see the current speed. The lower number is for "speed I" the high number for 'speed 2" (they are exactly 2x apart).
  4. Speed switch;; 0 is off, 1 is low speed and 2 is twice as fast.
  5. The normal on/off switches; prevents the machine from switching on spontaneously after a power failure -and- enforce a current limit/emergency stop.
  6. Emergency button. Do not use as an on-off button !
  7. Limiters for the travel
  8. Small scale; which you can adjust to see the travel in mm.
  9. Handle to lock vertical travel.
  10. Keyless drill chuck (taper not yet measures)


The drill press is classed as a normal, somewhat dangerous machine: instructions is mandatory in person. It can be used any hours -- but be kind to our neighbours.

Beware that unlike the small and [Drill press / boorkolom|lighter version in the woodarea]] -- this machine will NOT stop if something gets stuck - but typically ruin either the drill, your work or, if you are foolish enough to hold it by hand, your hand or other nearby body parts.

Use of safety glasses will generally be needed. The use of gloves is forbidden. It increases the risk of your glove (and with it your finger) getting twisted around the drill/rotating head.

Its main risks are flying sharp bits and body parts getting caught in something rotating or your workpiece rotating/spinning.

So clamp things well.

Changing speed

Always use the right speed; you get a nice round hole, it goes faster and the drills stay sharp. See Boorsnelheid RPM drilling speed for the speeds. See also SnijOlie BoorOlie CuttingOil

Speed is adjusted with the wheel.


Only adjust the speed when the machine is running !


Speeds and oil (metal)

There is a chart of speeds on the wall -- or see http://engineering.ucdavis.edu/wp-content/uploads/2013/08/lathespeeds.pdf

The larger your drill diameter - the lower the speed (Alu faster than steel faster than stainlesssteel/rvs); but limit countersinks/counterbores/stepdrills and similar `specials' to 200-300RPM.

There are three types of oil next to the machine. For most metals use the green oil.

Use the non-ferro oil if you find that the green oil stains your aluminiun/non-ferro metal (this is quite rare).

The third oil is generally not suitable to use with this drill press.

Safety Relay, Stop button

A safety relay was added; with a 4-6 amp current limiters along with an emergency stop button. Normal ground/earth wiring was added.

The current rotary switch does NOT allow for a switch-on block when in the wrong position. We need to find a replacement switch.



Likely [dalander switched]. We do not have a NC on the 'off' to prevent start when on.

Actions/chores and wishes


  1. earth wires connected, new plug
  2. emergency stop button
  3. add safety relay
  4. add current limiter
  5. paint bits with potential rust

to buy

# M10 blind bolts; shorter than current (2x) # M10 blind bolts; shorter than current (1x)

to do

  1. fix relay mount plate
  2. repair the hight adjuster
  3. make a knob to fix the top plate
  4. find/make a handle for the handwheel
  5. mount the hight adjuster
  6. Lift onto table and fix with M10 bolts.
  7. print and laminate safety card
  8. check rotation & fix in wall socket (as the other one was correct).
  9. document machine
  10. document V-belt/snaar
  11. figure out if it is an MT2
  12. figure out how/if/where to oil it


  1. add water coolant (requires a new power cable with an 'N'; the relay has spare pole).
  2. add a light
  3. make replacement disk for hight adjuster.
  4. find a Dahlander switch with an extra NC for the safety relay
  5. find a plate with 0,1,2 rather than current 0,1,2,3 or repair the old one.
  6. (weld)fill holes in mounting plate
  7. add a RPM meter

Location and ownership

Located in the metal shop. On loan; Dirk-Willem van Gulik
