  • Thinning webs (drills)

    I've got a few drills that could stand to have the webs thinned. ...how far back should they be thinned? Since I don't have a thin wheel for bench grinder, I planned to just use one of those little 3" abrasive disks in a air cutoff tool. Anything wrong w/that approach?
    (I've never done this before. ..obviously)

    I use the corner of thee wheel. Use the corner of a slip stone on drills under 1/4".

    You'll mess up a few practicing but you'll catch on to it.

      Forrest:

      Do you have a problem with it rounding off the corner of the wheel? It certainly depends how many drills you are doing.

        Dress the wheel first so theres a nice crisp corner and use a light touch. Your holding the drill so it points almost straight up. With a little care you shouldn't touch the opposite face at all.

          If you are going to do several,then dress the wheel at an angle so it is larger toward the outsie of the grinder.Kind of looks like a cup type wheel.Works great.Grinding wheels are a consumable so dont be afraid to use it. Jim

            Thats why it is good to keep one wheel on your grinder just for grinding drills, toolsteel etc - so the wheel corner stays sharp - just what you need for web thinning, chip breakers etc. (and take the other wheel off and fit a linisher so you never use your grinding wheel again for all those other grinding jobs).
