Medical Forum / General / Dentistry / May 2009Emesco drill questions.... Help!
i have just become the proud owner of 3 ancient emesco dental drill motors with 2 workable drill sections. only one still has the belt in workable condition. i am trying to find out how to correctly thread the belts, what length should i get to replace the others (or is there only one length), where i can purchase new ones, and how to lubricate and maintain the handpieces that came with them. the one i have been able to operate obviously needs some lubrication, the handpiece heats up quickly. i intend to use these in our jewelry shop, we are forever needing another flexshaft type drill for stone setting, etc, and these would fill the bill. any help would be greatly appreciated, i have surfed for hours with no info found about maintainence and belt length, and no easy source for belts. thanks!

Most of the major dental suppliers should have belts. I'll look in the Schein catalog tomorrow and get the manufacturer name/ordering info if I get the chance.

If the handpiece gets hot, it is probably bad and needs to be replaced as well. Your personal dentist should be willing to order the parts for you if you cannot find them on eBay.

I still have my engine from dental school. However, from what I've seen of the dremel tools, they probably are every bit as good for this person's use, and smaller. However, the chromed engine does look nifty. Steve SignatureMark & Steven Bornfeld DDS http://www.dentaltwins.com Brooklyn, NY 718-258-5001 I used mine for 20 years. When it quit, I bought a Schein lab unit for about $400 (they are listed at $438.99 now). I've been perfectly happy with it. It's a lot quieter than any Dremel tools that I've seen. For the old units: Belts are listed for 6'6", 9'6", 9'8", &9'10" for $6.79 each. Handpieces are $159.99. Dartos > I still have my engine from dental school.

Better speed control with the dental units...the dremel is basically on or off.

Call a dental lab or supply house and tell them you have a 'jack-rabbit' that needs a belt. Gauge your new belts to the old ones. Don't throw the old ones out until you know the size. New belts are made of neoprene (I think), anyway they last a long time. -- W_B Take out the G'RBAGE wubbabubbazG@RBAGEyahoo.com Congratulations for the three emesco, I have one and I can not understand how to insert cutters. The handpiece there is no lever to open the chuck, you can unscrew only (from the tip), but the mills that I have in 2:31 envelope diameter do not enter. I send you pictures but I did not understand how to do, I am somewhat inexperienced with this site.

The burs are 3/32 inches in diameter which is something like 2.31 mm. The end of the handpiece has a pulley and there is a "knob" at the end of the pulley. This is a screw that tightens the chuck. To change burs you loosen the screw counter clock wise about 1 or 2 turns and the bur should loosen and you can pull it straight out, insert a new one and tighten the screw finger tight only. If the handpiece makes squealing noises or get hot, either lubricate with light oil or replace the bearings. I have never had good luck repairing these handpieces. Parts are hard or impossible to get. Cheap handpieces do not have good bearings and do not last long. The belts can be obtained from dental supply houses. There should be an adjustment for the extension of the arms which will tension the belt. Without an old belt to measure replacement may be difficult: use a string to follow the path and buy one belt on each side of the measurement just to be sure. But first play with the legnth adjustment to make sure that you are in the ballpark.

In the meantime I bought another Emesco and his invaluable help I can make them work. Thank you very much. Nicola Ripandelli >These units are workhorses.
