  • Drill doctor
  • A fiew yeas ago I bought a Drill Doctor. I never took the time to set it up and use it.
    I have been throwing bits that were broke, chiped or i had hand ground and did not get the angels just right into a bucket. Christmas week I got it out and sharpened a couple hundred bits.
    It is very simple to use and I was realy impressed with the job it did.
    I saved hundreds of dollars worth of drill bits.
    The Drill Doctor I have is the older model 750. The new one is the 750X to replace it.
    The diamond stone is not cheap to replace, about $25. but the stone that came with it is still good.
    I did order a spare. The owners manuals has some good tips also. It tells that with large bits the center
    point wears more than cuts and reccomends starting with a smaller pilot hole
    Well worth the money.

  • Boy, you guys must be a lot older than me......or a lot richer. I only have 50 old dull bits saved. Seriously, I've always wondered if the Drill Doctor worked well. Back in the '70's I had some kind power drill sharpener that made me suspect the value of any new ones. Good to hear all the recommendations.

  • I got a Drill Doctor for Christmas many years ago. It has certainly earned it's keep. All my dull bits now get tossed in a can until I'm out of spare bits. That means it's time to bring out the can and sharpen bits. Mine still works great and has never had the grinding wheel replaced.

  • Re: Drill doctor
  • I bought one new about two years ago Dave and have yet to take it out of the box. Guess now in order to keep up with the Smiths, I'll have to get it out and set it up. Like the rest here, I must have several hundred old bits lying hither and yon! Thanks for the kick in the britches as I obviously needed it!

  • You can use a bench grinder to sharpen bits and it's a lot cheaper. The Drill Doctor, however, will get angles precise.

  • Re: Drill doctor
  • I have heard good reports about the drill doctors. I don't have one though.

    I built the sharpening setup in the picture using a 1750 rpm motor with about a 5" sheave and then to that sheave bolted a 6" piece of MDF with pins sticking up out of it. The pins go into holes in another piece of 6" MDF that I adhere round pieces of sandpaper to. I have several interchangeable 6" discs with different grits of sandpaper on them. I use this tool to sharpen just about all my hand tools, chisels, plane irons, etc. I also found out that it works well for free-hand sharpening drill bits.

    The finest grit of the discs is 600. After I sharpen a plane iron or chisel on the 600 grit, I move over to a diamond stone and then to water stones, then to leather strope wheel.

  • Re: Drill doctor
  • I have the 750x if you watch the video it shows you how to make a split point.Works good for keeping drill centered. The only problem is pretty soon you have all your bits sharpened and you go around looking for more to do.

  • Pilot point drill bits
  • Does anyone use pilot point drill bits? Are they as good as advertised?
    Can they be resharpened with the pilot point there?

  • Re: Pilot point drill bits
  • I like pilot point bits but I have not found a way to resharpen them. I have the same drill doctor and really like it. I have not had to replace the stone yet but I may have to soon.

  • Re: Pilot point drill bits
  • The pilot point can be ground off.I have used the General Tool drill bit Sharpener since 1970.It costs 28 bucks now.There is an import copy for 15 bucks.A D Mc Burney Sharpener cost 3 bucks in 1960.Still use one in my shed shop.I welcome the tool forum.Big drills can be sharpened free hand if the original angles are still there.
