Drill Bit Sharpener

I have used the one Mattax suggested, a Sears electric sharpener (I gave to my son) and currently have a Drill Doctor 750. They will all work fine, but as mentioned above understanding the angles is important. When you get one don’t get in a hurry as there is a learning curve involved.
My Drill Doctor ‘will’ do a split point up to 3/4”and care needs to be taken to not destroy the sharpening wheels.
Also as mentioned, the under 1/8” bits are better to just replace. Too difficult to index correctly.
