Hello straydog1024,

The model 275 has the the same armature as a model 395. Which means the shaft is the same size and thread. It's my thought that the 2615297355 is a match.

-WJA

The sleeve is part of the armature assembly. I used a piece of clear plastic tubing that was a snug fit and a little super-glue. Has been working for over 2 yrs.

I have had the same problem with two tools. These little drive collars don't seem to be available anywhere. Makes me want to run right out out and buy another Dremel product. How about you?

Mine did the same thing after about 2 years of "normal" use. I bought a replacement (a whole new tool), and it did the same thing after 6 months. I too changed the brushes but could not get either to work again. I really don't have an answer for you just wanted you to know your not alone... kinda makes me glad my units retail for about $30.00 and not those at $110.00. Pretty much convinced since Bosch bought out the Dremel company that the quality is not the same.

I've had mine longer than 2 yrs but it's had very little use. It also showed signs of "heating up" but not enough to be alarming, & just quit. I found that by putting pressure on the blue plastic button on the side [I thought it might be a reset button] that it would run again but quit as soon as the pressure was released. Curious, huh? Unless somebody can tell me how to fix it, it's toast. I'd rather pay more $ & have one that would last longer. I've had a 2 speed a lot longer & used a lot more that still works like a charm.

I have the same problem. All the blueprints for the model 275 show no shaft lock. Mine has one and the words "type 3" follow the model number. The shear pin seems to be there to make up for the longer body that holds the shaft lock feature.
