    Question Tapered Drill bit/countersink

    Doing a little searching and coming up empty. Can anyone recommend a really good tapered drill countersink set up? Every online search ends up at Amazon. Mostly #8, #10 and #12 screws. The cheap set I have now is just that. Bad set screws, loose countersinks and stop collars.
    Who has the best? Lee Valley? Irwin? Any advice would be great.
    Thanks
    Rob

    Fuller makes them, and several vendors sell them.
    The countersinks are available in high carbon steel or high speed steel.
    I have purchased them from Jamestown, and Mc Master Carr.

    The good ones are from W. L. Fuller. Amazon has some of the line, Jamestown has most of it.

    OK, I type slowly.

    Rockler sells some tapered ones called Insty-drive that are halfway decent. I picked up a set recently that was on sale for half-price. Sales seem to be regular. So far they cut cleanly and the collars stay in place but I don't use them all that much so durability is not known. What I like about them is they are hex shaft so drilling and driving with one tool isn't a pain.

    Fuller bits are the best, used them for 50 years

    Yup, go with Fuller. Life's too short to put up with crappy tools.
