Bought one few months ago. Takes a little while to get the hang of it but them youve learned how to use it properly and can sharpen those broken or dull bits efficiently and accurately. If the tip of a bit is broken, simply sharpen it first roughly on a bench grinder then finish it up with the Drill Doctor.
