    Ave been watching your videos for 2 years.
    I laugh with ya, love with ya , I cry with ya. I even learn a thing or two sometimes. However this video definitely show cases true bumble fuckery. The Drill Doctor is a fantastic piece of equipment.

    My drill doctor doesn't sharpen bits under 3/16 very well but does sharpen the bigger bits very well.

    Personal bits sharpener.

    I'll never buy one of these as I prefer to sharpen my drill bits sitting down 🙁

    Replying to a 7yo AvE vijayo. Hopefully the yt algorithm gods will pop this into other people's suggested 🙂

    Drill Doctor is sort of a hoky name but most people don't know DAREX the company that builds them makes some very high end industrial drill sharpeners.
    The company I retired from used a DAREX CNC Drill sharpener that was super accurate and fast.
    It was used in a production drilling department so it had a daily workout.
    It cost $50,000 quite a lot of money but well spent as it would save buying new replacement drills and also it made a better grind than even a high quality $$ industrial bit had. You had lots of options for some performance grind profiles.
    Sounds like crazy money but it paid for itself in a year.

    That machine and this hobby grade are no comparison but for what this is it does a good job.
    It has some knowledgeable engineering behind it for its price point.
    If you have a bench grinder it would be to your benefit to rough grind badly beat up drills first and save this for a finish grinder.
    Or regrind your bits sooner than later. Or buy industial quality bits instead of Chinese box store bits..there is a huge difference.

    I have a Drill Doctor and it does a better job than I can do by hand anymore and that's how we did it in the old days, toolmakers had to know how to accurately sharpen by hand.

    Love ave, but sometimes reading instruction manuals helps for using things correctly

    What is on the CD?!

    After reading and then finally understanding what the instructions are trying to relay, for me it was the position of the collet to the bit and the distance from the tip..After I learned how to fine tune the position and through a long learning curve this is more accurate then by hand, split point are no problem. It works best keeping bits sharp, before they get to dull . So what I do is touchup my bits while still some what sharp. A chip or really dull bit takes a long time. For me it works and has paid its way

    I just got the Drill Doctor 750X, and for the second time tried to get the process down. I bought one…..oooooh…..when they first launched, and hated it!! But the second go round, yes works perfectly, very sharp and darn near like new!! Sharpened a whole 29 bit set that was dull as frig. Drills like a hot dang!! Alignment is key, and you have to get the geometry down, otherwise you end up like AvE!! Don't knock it down, it does work, the manual sucks, watch some Youtube videos on the process and what you are looking for.

    I used mine 3 or 4 times till the grit wore down the plastic and lost the angle of the dangle. I cut all the plastic crap off from around the diamond stone and still use it to sharpen carbide bits for the lathe.

    200 bucks for that piece of shit? It's tool grade alright.

    I like mine but I don't use that until the whole coffee can is full of used bits
