Nice tool if you want to sharpen drill bits like I do. For the ease of sharpening and the quality of the finished bit I would purchase again without hesitation. They can be done by hand on a grinding wheel but don't come out near as sharp or hold an edge near as well.
Get one but don't buy 3 of them like I did. Couldn't ask for more. A+++ Just as expected, delivered quickly. But. They last a very long time. I've sharpened hundreds of bits and never needed to change the original wheel.
This part is for the older "classic" series of Drill Doctors, NOT for the newer version that Amazon now sells. However, they still list this as an accessory for the X series and list them in the "better together" link. It is the wrong diameter, as the newer wheels are smaller.Other than that, it may work fine, but it won't fit my DD, so I can't tell.Note: Amazon updated the description line to be correct now. Be aware that the description of this item is incorrect, with the exception of the manufacturer's description line. Only the models without the trailing X in the model number can use this. Sigh. All of the lines above that say it is for.500X, 750X are incorrect.
I.e., remove the current wheel, turn it end-over-end, and reinstall. This may sound silly, but it worked for me. Put the Drill Doctor in the freezer for 30 minutes and then, try again while the unit is still cold. 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. The drill bits I sharpened did not wear out the middle of the wheel, so reversing it provided new wheel life. The cold shrinks the metal parts just enough for the old wheel to slide right off. 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.
If you buy the sharpener it is only sensible to buy a replacement wheel, bought and got it with the initial purchase of the Drill Doctor, the original works great in the machine, no reason why the replacement wheel shouldn't bring the same satisfaction.
