1 3/4" 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
