Spec Overview  

The DeWalt DWE315K is very similar to other OMT models in the market in terms of the way it look--sharing the familiar bullet shape and approximately the same dimensions with most of its competition; The DeWalt DWE315K is a roughly 13″ long OMT unit that weighs in at about 3.1lbs.

You just squeeze down on the silver lever and you are able to disengage the clamp and free the blade attachment. While the Quick Change of mechanism pretty sleek, you might need to wait for the previous blade attachment to cool down a little before it’s safe to touch.

The DWE315K’s Quick Change system is compatible not only with all DeWalt attachment across their OMT line but also with OMT attachments of Porter-Cable and Black & Decker OMTs--as these brands are practically the same group of companies and therefore share the same type of quick change technology.
