Use tips 1. All oscillating blades one must take it slowly and do not push the blade or it will overheat and go blunt very quickly. Also another tip is to keep the blade moving and not let one area of the teeth do all the cutting. 2. Don't force them! Let them cut at their own pace and move the blade sideways back and forth a little to let all the teeth work on the cut. That way the teeth in the middle won't get all the heat and wear. If you do lose a couple of teeth the blade will still cut. Can meet a variety of needs, which could be used for workshop, household or other place. oscillating tool blades
