Some tips for using our Ultra-thin Saw Blades

 

  1. Always, wear eye protection!

  2. Make sure the blade is mounted in the mandrel so the teeth point in the direction of the Dremel tool rotation. This is normally with the teeth pointing toward the left when viewing the mandrel so the locking screw is facing you.

  3. Position the Dremel tool so the direction of rotation throws any chips away from you face and eyes, not toward them.

  4. These saws are very sharp! When mounted in a running Dremel tool they can cut through your flesh as if it were warm butter! Use them with extra care (picture: spinning scalpel blades).

  5. Do not exceed 30,000 RPM rotation speed.

  6. For best results clamp, or firmly hold your Dremel tool in place and move your work (article to be sawed) under the rotating blade. This may seem backward to the way a Dremel type tool is normally used, but if the objective is to saw a straight thin line or cut a straight thin slot, a small amount of hand movement can cause the blade to wander. Make sure your Dremel tool is held firmly and will not vibrate loose.

When we sawed the slot in our telephone pole example, we clamped our Dremel in a table vise with rubber jaws (so as not to damage the Dremel tool). We then held the pole against a square scrap block of plastic so that the length of the pole was parallel to one of the straight sides of the plastic block. We held the pole in place with double-sided tape. We then taped a second scrap block to our workbench to act as a fence for the first block to slide against. We made sure it was positioned so that when we slide the first block back and forth with the pole on it. The saw blade was positioned directly over the pole and the pole moved keeping the blade centered on the pole. We then turned on the saw, put several pieces thin card stock under the block with the pole (to raise the pole up so the saw would contact the pole), and slowly moved the block to cut the slot. We the repeated this procedure adding a few more pieces of card stock. This let the saw cut the slot again slightly deeper.

  1. Run you Dremel tool on the proper speed and feed you work slowly.

When sawing plastic, if you run the saw too fast, the heat generated by the cutting process we be sufficient to cause some melting of the plastic. A much cleaner slot will be produced at the slowest cutting and feed speeds. If sawing or slotting wood, this is not as great a concern. If sawing soft metal such as aluminum, white metal (pewter) or brass, adding a small amount of light cutting oil will greatly extend the life of the blade. Do not make deep or fast cuts when cutting or slotting metal materials. Do not attempt to cut steel, iron or stainless steel with these saw blades. Only cut plastic, wood or soft metals.

  1. Store you saw blades so the teeth are protected from damage. A closed container is a good idea. That way, if they're kept in a tool box or drawer, they won't be damaged by contact with other metal tools.
