Operating Speeds for Accessories - (cont.)

The speed of Model 800 is controlled by rotating this dial to desired setting on dial

Switch Setting	Speed Range
0	OFF Position
* 2	5,000 – 11,000 RPM
4	12,000 – 20,000 RPM
6	21,000 – 25,000 RPM
8	26,000 – 30,000 RPM
10	31,000 – 35,000 RPM

*2 is the maximum speed setting for wire brushes.

To aid you in determining the optimum operational speed for different materials and different accessories, we have constructed a series of tables that appear on page 13, 14 and 15. By referring to these tables, you can discover the recommended speeds for each type of accessory. Look these tables over and become familiar with them.

Ultimately, the best way to determine the correct speed for work on any material is to practice for a few min- utes on a piece of scrap, even after referring to the chart. You can quickly learn that a slower or faster speed is more effective just by observing what happens as you make a pass or two at different speeds. When working with plastic, for example, start at a slow rate of speed and increase the speed until you observe that the plastic is melting at the point of contact. Then reduce the speed slightly to get the optimum working speed.

Some rules of thumb in regard to speed:

1.Plastic and materials that melt at low temperatures should be cut at low speeds.

2.Polishing, buffing and cleaning with a wire brush must be done at speeds below 15,000 RPM to prevent damage to the brush.

3.Wood should be cut at high speed.

4.Iron or steel should be cut at top speed if using tungsten carbide accessory, but at slower speeds if using high speed steel cutters. If a high speed steel cutter starts to chatter — this normally means it is running too slow.

5.Aluminum, copper alloys, lead alloys, zinc alloys and tin may be cut at various speeds, depending on the type of cutting being done. Use paraffin or other suitable lubricant on the cutter to prevent the cut material from adhering to the cutter teeth.

Increasing the pressure on the tool is not the answer when it is not cutting as you think it should. Perhaps you should be using a different cutter, and perhaps an adjustment in speed would solve the problem. But leaning on the tool seldom helps.

Your 10.8v Cordless Rotary Tool can be used with all screw-on attachments for added versatility. A few older attachments, such as 2217 Tool Holder, 330 Router, and 231 Shaper / Router Table are not com- patible with the 10.8v Cordless Rotary Tool.

The 212 Drill Press requires a free adapter kit (available April 2004) which you can get by calling Dremel at 1-800-4-DREMEL.

The 225 Flex Shaft is compatable with your tool, but you may experience reduced run times when using it.
