Rotary Tool Introduction
From CoMakingSpace Wiki
This is the content required for an introduction to our rotary tool - reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)
Let's begin! First off, make sure you have read the machine's manual.
Safety
Dangers
- rapidly spinning exposed chuck & bit, binding can cause kickback
- generation of hot sparks that are expelled in varying directions
- sparks fly very far and deposit themselves as fine dust
- the workpiece heats up and stays hot for a while
- has no prevention of turning on after loss & restoration of power (keine Anlaufsicherung)
- (metal) dust can be a health hazard when inhaled
- aluminum can clog an abrasive disc and cause it to overheat until it breaks
Precautions
- make sure the collet is properly tightened around the inserted bit
- stay clear of the rotating accessory and the direction where kickback might occur
- wear goggles to protect your eyes
- wear ear defenders if its too loud (normally you don't need them)
- put small workpieces in a vise or clamp them down
- if the power has been lost for whatever reason, always return the power button to the "off" position before restoring it!
- let the tool reach full speed before contacting the workpiece
and, depending on the bit and material:
- wear a proper dust mask when generating dust or sparks
- wear suitable gloves to prevent burns from sparks or the workpiece
- do not attempt to vacuum up sparks! The dust collection bag could catch fire
- do not use abrasive discs on aluminum
- do not apply any side force to cut-off wheels, they could shatter!
- in general only little force should be applied while cutting. Let the tool do the work.
Suggested Reading
When you use this tool, please read & add to the information about rotary tool bits!
Demonstration
The tutor will show you these steps in detail:
- inserting a bit
- attaching a handling accessory, e.g. the flexible shaft
