Drill Doctor DD500X Drill Bit Sharpener

Q: does aligning the chuck to 118 also applies for 135 degree geometry and what is the significance of the notches on either-side of 118?

Yes it does. The significance of the notches enable you to alter the relief and chisel angle of the drill bit. By going + you will increase the relief angle of the drill bit, useful for high speed drilling in softer metals. And vis versa going -. 45 degrees is the correct chisel angle for a drill bit. By using the alignment notches + or - you can make the drill bit more or less aggressive. A less aggressive drill has a lower chisel and relief angle. I love mine, easy to set up and use. Hope this helps.

Q: can the degree of angle of cut be changed

Yes, you can choose between 118 and 135 degrees. Many of the videos you can find on youtube and the video that comes with the sharpener show you how to do this. you may want to take a look at the following links: https://www.youtube.com/watch?v=8wWzW8BjtiM and https://www.youtube.com/watch?v=M6bC5imB31A

Q: Is the 500X able to sharpen 13mm bits?

I don't have a 13mm bit to test, however I have a 12mm brad point bit and it fit in the collet/chuck with a little room to spare. So you should be able to sharpen a 13mm bit.
