Title: Installing a new Drill Doctor Diamond Wheel
Review: Drill Doctor Diamond WheelThis wheel is the same quality as the original part, which, in my case, lasted through hundreds of sharpenings.An alternative to installing a new wheel is to reverse the existing one. I.e., remove the current wheel, turn it end-over-end, and reinstall. The drill bits I sharpened did not wear out the middle of the wheel, so reversing it provided new wheel life. Once it's been reversed, and it's worn again, a new wheel is required.If you're having trouble getting the old diamond wheel off the spindle, here's a tip told to me by Drill Doctor. Put the Drill Doctor in the freezer for 30 minutes and then, try again while the unit is still cold. This may sound silly, but it worked for me. The cold shrinks the metal parts just enough for the old wheel to slide right off.
