1 1/2" O.D. Premium Dry Vacuum Diamond Core Bit
Vacuum Dry Drilling Core Drill Bits
For Brick, Block & Some Concretes*
Dynatech Vacuum Dry Drill Bits are an inexpensive
and fast way to drill holes in brick, block, and some
concrete.* Perfect for situations where water cannot
be used or when dust control is a factor. Simply screw
the vacuum swivel on your grinder or 1/2" drill,
connect your vacuum hose from any vacuum source
(shop vac, wet/dry vac etc.) and you are ready to drill.
The vacuum suction pulls air down the outside of the
bit and across the diamond segments. This aids in
cooling, and removes cuttings quickly so that the
new cuttings can be created. Fast removal of cuttings
eliminates bit binding, provides faster cutting and
produces longer bit life.
*For hard concrete or concrete with steel reinforcing
(Rebar) use Dynatech Wet Cutting Core Bits
