    As a flooring company we drill 3/16 size holes for aluminum plugs into some really hard ass concrete everyday. We have been using the Bosch blue granite bits from lowes but they very rarely stock enough. My question : is there a supreme short shanked bit that comes in a reasonable quanity?
    - Guy C



    I have the best 3/16 x 4" bit on the market. It is hex shanked so it does not spin in you drill chuck.

    We can also work out special pricing on large quantities.
