Introduction
The Dremel tool is a rotary tool, or machine that turns small cutter bits very fast to cut, grind, drill, sand, or etch a variety of materials, including wood and metal. Dremel is a specific manufacturer, but the name is very often used to describe similar tools even if they are not Dremel brand.



Warnings

 * Eye Injury Risk - Always wear goggles when using this tool
 * Dust Hazard - Many types of material make hazardous dust when cutting, grinding, or other work with this tool. Read the Manual links below for more detailed information.  Wear a dust mask when using this tool.
 * Hearing Risk - Certain Dremel tool operations can make loud or high frequency noise. Hearing protection is available in the HCC lab to mitigate this, and should be worn pretty much any timem the Dremel is used to cut metal, or at high speeds.
 * Flying Debris - This can be caused by many things, each with their own preventative measures. See "Detailed Instructions" and the [manual] for more information. (might want to make a separate section for this in detailed instructions)

Quick Start Guide

 * 1) Make sure you have read and understand the "Warnings" section (above) and the Safety section of the manual. (see below for link)
 * 2) Put on all appropriate personal protective equipment (ppe)
 * 3) Secure loose clothing, long hair, jewelry, ID tags, etc.
 * 4) Don't let others talk to, distract, or get too close to you when you are running this tool.
 * 5) Select a suitable bit.
 * 6) *Inspect the bit for damage before using it.
 * 7) *Do not use dull/damaged bits.
 * 8) Install the bit securely in the chuck.
 * 9) *Make sure the arbor, or shaft, is the right size for the chuck.
 * 10) *It may be easier to remove if you don't stick it all the way in.
 * 11) Clamp the item you are working on securely. Do not attempt to hold it with your hand.
 * 12) Make sure that you and others nearby are out of the plane of the rotating bit, so that if it breaks apart, injury risk will be minimized.
 * 13) Power up the tool and gently push the cutter into your part.
 * 14) *Hold the tool firmly so that you can maintain control if the bit catches
 * 15) *Be aware of where your chips/dust are going, and make sure they are aimed away from other people.
 * 16) When you are finished, put the tool away and clean up your scraps and debris.

Manual
Before attempting to use this tool, read and understand pages 14-16, inclusive, of the manual. Make sure you read:
 * section 1, "Work Area" through section 5, "Service" (p.14)
 * "Safety Warnings That Are Common For Grinding, Sanding, Wire Brushing, Polishing And Abrasive Cutting Off Operations" (p. 15)
 * "Kickback And Related Warnings"
 * all safety warnings related to grinding and cutting off (p. 15-16)

Personal Protective Equipment (PPE)
The Dremel tool has the potential to produce high frequency noise, flying debris, and hazardous dust. To reduce your exposure to these risks, you must wear: You may, depending on conditions, want to wear:
 * goggles
 * hearing protectors
 * gloves
 * apron
 * dust mask (recommended for most work)
 * face shield

Distractions/Bystanders
As with any power tool, you should devote your complete, undivided attention to the Dremel while using it. Do not talk to friends or group members, don't let them talk to you, and don't let them get too close to your work area. "Anyone entering the area must wear personal protective equipment." Additionally, they should be:
 * Out of the plane of your rotating cutter
 * not in the path of your cutter's chips and dust

Loose Clothing, Jewelry, etc.
To prevent entanglement in the Dremel tool's spindle, you should remove or secure:
 * long sleeves
 * ties
 * jewelry (particularly necklaces and bracelets)
 * long hair
 * ID tags/keys around neck

Flying Debris Warning
Flying debris can be caused by broken or disintegrating bits. The risk of this can be reduced by:
 * assure that the bit diameter and thickness is within the rated capacity of the tool
 * assure that the bit's arbor fits the chuck properly

Bit Selection

 * Select the proper Dremel bit for your work. Resources available to help you do this include:
 * wikiHow Dremel tool tutorial
 * Dremel tool instructables page
 * blueroofdesigns.com Dremel tutorial
 * the chart on pages 4-6 of the manual
 * Inspect the selected bit for damage and wear.
 * Make sure that bit RPM rating meets or exceeds max RPM of tool To do so,
 * Use the Dremel Accessory Chart to determine what your bit's part number is.
 * Search online for "dremel rpm." (replace brackets and bracketed text with your part number)
 * Check the results for the maximum RPM of your tool.
 * (Note - someone could greatly improve this wiki by finding or building a chart of Dremel bit RPM vs. part number.)

Bit Installation

 * Disconnect power by removing the battery or unplugging the cord (turn the switch off first)
 * Select the proper collet to hold the selected bit. (currently, HCC has only one collet, this is for future use)
 * Insert the bit's arbor most, but not all, of the way into the Dremel's chuck. (leaving it out a bit helps when trying to remove it)
 * Make sure that the bit's arbor, or shaft, fits the chuck properly. It should be snug, but not tight, with the nut loose. (prevents unbalanced spindle)
 * Tighten the chuck with the chuck wrench. Press the lock button to keep the spindle from turning while tightening.
 * Remove the chuck wrench from the Dremel before powering up

Starting Your Work

 * Clamp your material securely, either in the vise or to an immovable surface.
 * Select RPM from the chart in the manual based on your cutter bit and material.
 * Hold the tool firmly to be prepared for kickback.
 * "A gentle touch gives the best control and reduces the chance of error."
 * Be aware of where chips and debris are going.
 * "Always feed the bit into the material in the same direction as the cutting edge is exiting from the material (which is the same direction as the chips are thrown). Feeding the tool in the wrong direction, causes the cutting edge of the bit to climb out of the work and pull the tool in the direction of this feed."

Cleanup
As with all HCC lab use, you must clean up your work area when you are finished. In this context, you should:
 * Put the tool away at least as neatly as you found it, where you found it.
 * Clean up your scrap materials.
 * Clean, ideally vacuum, the dust and chips produced by the cutter
