    Default Vintage Mathisen auger bit question

    Hi all,

    I recently bought these auger bits off FB marketplace. New to hand drilling, but they don't look quite like the ones online.

    The bits in this photo don't seem to have a spur. It looks like that was the intended design, so now I'm wondering how I'm meant to sharpen them and whether they're still suitable for fine work.

    I'm not even sure what type of auger bit this is. Not a Mathieson. Any ideas?

    Hope the images attached properly.

    Thanks
    Jay

    From memory they look like a scotch pattern auger to me.

    Hi Jay,

    I asked a question about a brace bit recently and
    Geoff posted a lot of info on brace bits. It says yours is a
    Scot bit. If you scroll down the page you will come across
    a reference called Bull nose brace bit.

    Hi Ja
    Potts is correct they're scotch bits, probably the most frequently found type here in Aus' but not the best for fine work, the lack of spurs meaning they can tear out badly as they are entering the wood. There is a fair bit of info on sharpening on this forum if you do a bit of a search.
    Your second pic is gimlet or nail bit.

    Cheers,
    Geoff.

    I've got a set of Titan (made in Tasmania) scotch pattern bits. They do have spurs but they are above the lip unlike the jennings style ones. Make sure you sharpen the INSIDE of the spurs not the outside. They are supposed to run straighter than the jennings style ones which they say can deviate if they hit a knot or cranky grain. Mine work well in australian hardwoods but you have to be a bit careful when you start your hole and it helps a lot if the lips and spurs are really sharp. I can see in your photo that the middle one and the one on the right need some work on the spurs.

    Mick.

    Thanks for the responses. Good to understand a bit more about auger bits.

    Looks like I'll have to check the bits more carefully in future

    Thanks!
