Drill Introduction
(deutsche Version: Bohrmaschinen-Einweisung - Änderungen wenn möglich auch dort eintragen!)
This is the content required for an introduction to the following tools:
Reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)
If you need this introduction, please reach out to the following tutors: Patrick, Lukas, Johannes, Keno, Luzian, Martin, Luca, Jakob.
Let's begin! First off, make sure you have read the machine's manual, if available (check its "InfoBox" in the wiki for instructions how to find it).
Safety
(Breathing protection recommended depending on bit and material)
Dangers | Precautions |
---|---|
exposed & rapidly spinning chuck |
|
possible kickback due to a drill bit that binds with the material |
|
a drill press table can destroy your drill bit | always check whether the tool movement you are planning is possible before turning it on
|
drill presses: belt-based speed selection | unplug the drill press before opening the belt housing at the top |
some drills do not have a prevention of turning on after loss & restoration of power (keine Anlaufsicherung) | if the power has been lost for whatever reason, always press the "off" button before restoring it! |
the chuck key can be flung at you if left in the chuck when the drill is turned on | always remove the chuck key right after using it, do not leave it in the chuck any longer than necessary |
Speed Selection (Drill Press)
- unplug the drill press
- open the belt housing
- check the explanation inside the top to see what speed is set/which belt setup you need for your desired speed
- loosen the screw holding the motor at distance
- pull the motor towards the front to loosen the belt
- repeat as necessary:
- move the side of the belt that will go to a smaller pulley up or down (whichever you decided you'll need)
- follow with the other side of the belt
- double-check you have the belt set up for the speed you wanted and that both sides are on pulleys at the same height
- push the motor back and tighten its screw again
- close the belt housing
- plug the machine in & you're ready to drill!
Torque & Speed (Cordless Drills)
Please follow these simple guidelines to avoid damage to your screws, material, or the drill itself:
- the torque (DE: Drehmoment) can typically be set with the ring before the chuck
- better start out too low than to round your screw in the first try - wood may also be damaged if screws (especially self-tapping/"Spax") are inserted too deep
- the drilling setting at the end of the scale should only be used for drilling, it creates way too much torque for screws and screwdriver bits!
- excessive torque does NOT make you screw faster, it really just wrecks stuff...
- there may also be variable speed settings (slider on top)
- only change when the drill is fully stopped
- use the slower one (1) for screwing to prevent slipping
- the higher speed can be used for drilling
Suggested Reading
Besides these safety notes, you should read about the different drill bits to know what you're doing! Different materials usually require different bits, and the drilling speed depends on the bit as well as the type of material.
