RE: [Killietalk] drilling glass

["David Lains" <david at zfin_org>]

Hi Gary

That figure is way off.  A diamond coated bit (the good kind) is over price
at $100.  The $300 ones are diamonds embedded in a matrix that wares off
exposing new diamonds.  They are designed for a life time of drilling
concrete, marble and granite.

Best fishes
David
