I tried to use the screwdriver tip to tighten the slotted set screw and quickly discovered that the provided tool was too thick to fit into the groove in the set screw. If you already have one, with a soft metal housing for the diamond tip, you might wish to try some Locktite on the set screw and perhaps even the diamond tip where it contacts the soft metal housing. On the very first tool, after engraving the serial number, the diamond tip began to loosen and slip out.
The set screw is just fine, but the metal that was threaded for it to go into is made of a metal so soft that it cannot withstand a single turn of the set screw that is essential to hold the diamond tip in place. Be sure to take note of the different strengths of Locktite so that the bottle or tube you buy will be effective. I'm still rather incredulous that this tool would be made so poorly; perhaps they had a bad batch that got out on the market.
I bought this engraver to mark all of my tools with serial numbers and my name. When I returned to the engraver to tighten the set screw the tool fit perfectly, and with one turn the screw, all the threads stripped out of the tool, not off the set screw. My engraver will be going back, and I do not think I will be purchasing any more Dremel products in the near future.
I reached for the included little wrench with a standard screwdriver tip on one end to tighten the set screw that holds the diamond tip in the tool. I was a little miffed, but just walked over to a benchtop polishing wheel to remove a small amount of steel from the tool so that it would fit in the screw for which it was made.
I have only used this tool a few times, but it has worked very well.I was surprised at how thick of a piece of metal it will make a cut in.
powerfull and not too loud. I am using the diamond tip with it. glad i own it. great little unit. works on all metals including saw blades and router bits.
