  1. Note that the 22 dollar attachment is around 100 year old drill bit sharpening jig. It has a learning curve. What you should test is how accurate holes are after sharpening. I can sharpen a drill on a bench grinder faster and with sharper edge then any sharpener, but hole accuracy is an issue. At around 1/4 inch it is hard to grind by hand even when measuring lips and angle guide. Finally finish is far nicer on belt sander then on a grinder. Darex makes high end drill grinders, drill doctor is their home shop brand - hency it's plastic case and weak motor.
