  • 135* drill point gauge

    I'm looking for a gauge to measure the point of a 135* drill when I am sharpening. I see many gauges are for 118. I found a mechanix mate DPG1 that is discontinued that is for both points but is discontinued. It is a really simply design and would work great.

    Do you have a gauge that you like that is available and not discontinued? Thanks for the help.

    Got a hunk of 16 ga sheet metal or 1/16 Starrett stock? Make a 135 degree drill gage. It's a simple bench job and the accuracy good workmanship brings is plenty good enough. If you have a filing machine handy you can make it real pretty.

    For that matter, use the protractor head and scale of your combination square or a protractor like this:

    Or a bevel protractor if you have one.

    If you're looking for graduations on the angle to control lip symmetry forget it. Dividers are not only easier to see but more accurate.

    Cultivate your eye. You'd be amazed how accurate eyeball comparisons can be once the nervous uncertainty wears off. I was taught to sharpen drill by eye alone back in the day (1961) and have never used a gage. Drills I sharpened (usually) made two equal chips and seldom drilled 0.005" oversized. But then I was blessed by a good etc and it was cultivated early by emulating and eventailly surpassing my dad's. Until 2004 I've never used dividers to check lip symmetry.

    Now my eyes are such I have to use a Drill Doctor. Rats!

          Q? When did the 59deg drill bit start being called the 118deg drill bit?

            Since it was called drill point angle. Probably the same time when drills were called drills and not drill bits
            Amount of experience is in direct proportion to the value of broken equipment.

              My metalworking teacher used to go potty if you called a drill bit a drill bit

                Hey arent we supposed to be able to work with metal or Mangle it .
                Why no drill a 1/16 inch hole in a piece of flat metal preferably steel also 1/16 inch thick and by whatever means that you are comfortable with cut out a "V " with the 1/16 hole at the pointy end , then use a file and a good sharp drill as a guide to file the v until it is the same as the point you wish to grind.

                I was taught to do that many years ago to be able to grind HSS bits for applications like threading or to be able to duplicate a tool for a job which had to be done in batches some months apart

                Go and try it , you may be pleasantly surprised at the results if you are patient , you may even end up with a tool which will give you years of service.

                  I thought drill bits were the wood work type were it had a large square lump on the end and fitted to a drilling brace used mainly by carpenters.
                  Drills were only used by metal workers!

                    A drill it the thing that spins a "drill bit" . Just as a lathe the thing to which a "lathe bit" is, in some fashion,
                    attached. Also a mill the machine in which, again in some fashion, a milling cutter is used.

                      No! they are "bits" . As in a "Brace and Bit" set. (longer time woodworker than metal worker)

                          The other is a Canadian company and shipping could be prohibitive.


                          Thanks for the help though.

                            I think I'm going to use a sliding t bevel that has length markings on it that way I can set the angle and lock it in and use the demarcations to compare for symmetry. And only 4 bucks.

                            Thanks for the help.

                              Damn fine print, why do they even show it if they can't provide it? All I saw was the in stock and closeout. Sorry.
