Step 1

Choose an accessory that is appropriate for the task you need to complete. For example, to sharpen an axe, use an aluminum oxide grinding stone; to cut a galvanized plumbing pipe, use a reinforced cut-off wheel; to cut a hole in drywall, use a drywall cutting bit. There is an attachment for just about every task.


Step 2

The switch setting will determine how fast the accessories spin: - Setting 2: 5,000 - 8,000 RPM - Setting 4: 9,000 - 11,000 RPM - Setting 6: 12,000 - 17,000 RPM - Setting 8: 18,000 - 24,000 RPM - Setting 10: 25,000 - 35,000 RPM For grinding stones, setting 8 is recommended; for cutting pipe, setting 10 is recommended; to cut drywall, setting 8 is recommended. Using the recommended cutting speed will help the tool do its job the way it was designed to do it. Note: Polishing, buffing, and wire brushing should be done at slower speeds (below 15,000 RPMs). Wood cutting, drilling, carving, etc. should be done at higher speeds (15,000 RPMs or more). Allow the performnce of the tool do the work. Do not force the tool if it is not performing the way you think it should. Use a different accessory or speed setting to complete the task.


Step 3

Clean the tool when the project is complete. Unplug the tool and blow the dust off of the tool. If you have an air compressor, use it to blow the dust off of the tool and out of the vents. Wipe the tool down with a damp cloth rag, and then store the tool in its tool case. Be sure to lock the lid!


Running your Dremel tool with worn brushes will permanently damage the motor. Replace the motor brushes regularly as needed.
