Q: What is Electronic Feedback?
A: The Dremel Digital is a high performing rotary tool because of electronic technology that helps “control and maintain” the speed you have selected. The permanent magnet motor not only provides the enhanced power, but high speeds of 5,000 – 35,000 rpm. High speeds makes any rotary tool unique from traditional power tools, but “consistent speeds” during any application make the Digital tool the top of the line in rotary tools.
Q: Why does this tool have a Digital LCD Readout?
A: The rear of the Digital tool contains an LCD readout indicating the selected speed of 5,000 – 35,000 rpms. This allows you to set your speed, in 1,000 rpm increments between 5,000 – 35,000 rpms. As long as the tool stays plugged in, it will be set for the selected speed. Just turn it on again and it’s set and ready to go!
Q: Is the Dremel Digital rotary tool compatible with all Dremel attachments and accessories that I own?
A: The Dremel Digital rotary tool has been designed to accept most current Dremel attachments; except for the Dremel XPR Planer, XPR MultiSaw, and 2217 Tool Holder. However, attachment models 212, 231 and 330 need a universal adapter which is available free from Dremel Customer service, 1-800-437-3635.
Q: Dremel offers the XPR Planer and XPR MultiSaw attachments; what are they and what tools can they be used with?
A: The Dremel 400 Series rotary tool was designed to use the XPR Planer and XPR MultiSaw attachments. The XPR Planer is a 2 1/4” wide guide with a “special fluted” bit that removes about 1/64” of material with every pass. The XPR MultiSaw has a reciprocating action using any jigsaw blade on the market. Its 3/8” blade-stroke allows you to cut many materials and thickness based on your blade length. These two attachments can ONLY be used on the Dremel 400 Series XPR rotary tool which offers the enhanced performance necessary to use the attachments effectively. Attempting to use the XPR Planer or XPR MultiSaw attachments with the Digital, 300 Series, Variable Speed MultiPro or any other Dremel or competitive rotary tools – will damage the rotary tool.
Q: How does the accessory system work with the Digital rotary tool?
A: The Digital rotary tool uses the same accessories and collet system as the current Dremel 300 Series, MultiPro or other previous rotary tool models. The accessory shank (stem part of an accessory) sizes range from 1/32" to 1/8". The collet, a slim aluminum tube with small slots, holds the shank portion of the accessory and will be tightened inside the collet when you tighten the black collet nut on the end of the Digital rotary tool’s output shaft. Use the wrench, provided in your Digital rotary tool kit, if you cannot firmly tighten with your fingers. For harder work load applications (i.e. routing, tile cutting, etc.) please always use the wrench to assure proper tightening.
Q: What are motor brushes and do I have to do anything to them?
A: Motor brushes work like oil in your car. The motor brushes (#2610921562) are located in the brush holder, under the brush doors on each side of the tool. The brushes should be checked every 50 hours of tool use. If the brushes are smaller than 1/8", they need to be changed. After changing motor brushes, the tool should be “run –in” for 5-10 minutes with no load. This will seat the new motor brushes.
Q: Why does the Digital have high speeds?
A: The Digital rotary tool has high speeds of 5,000 – 35,000 rpm. High speed, when coupled with the right accessory, is what makes the rotary tool so useful. The best results generally happen when taking a less aggressive, more frequent pass. Too much pressure on the spinning accessory and the work piece can damage the accessory and the work piece. If the accessory is not producing the desired result, we would recommend adjusting the speed, or trying an alternative accessory.
