Rotary Tool Introduction

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
