Dear Wayne,

    I use both, according to size of bit/drill etc. My comments about
    buying cheap electrobonded tools are based upon the apparent
    attrition rate of the more expensive bits on this particular job.
    Why wreck a $10 bit when a 30c bit will do under the same
    circumstances. I use Shell Ilocut oil for my bigger saws, a water
    soluble for my smaller ones and water on my drills etc as generally I
    have to due to the materials I work with. One of my students (day
    job) is doing research on a new bonding method for abrasives in metal
    that is rather interesting, simple as a plating bath but has the more
    precise profiles of a sintered product and greater depth of abrasive
    than the normal coated products so has nearly the tool life of a
    sintered continuous bonded product at a fraction of the cost. 

Nick
