How to Drill a Hole in Precast Concrete Tees

By Owen E. Richason IV ; Updated September 21, 2017

Precast concrete tees are used to support many types of fixtures. For instance, they may be used to support a bench or shed. To make use of these precast concrete tees, they will have to be drilled with pilot holes in order to fasten the fixture to the tees. This is not a difficult project, but will require a bit of elbow grease and some common tools.

Put on safety glasses, a dust mask and gloves to protect your eyes, lungs and hands.

Fit a masonry bit into a drill and tighten the chuck to secure the bit into place.

Pour some water on the precast concrete tee where you will be drilling the hole to suppress dust from flying in the air and keep the bit cool.

Hold the drill bit firmly against the precast concrete tee, leaning your weight into the drill. Pull the trigger and begin drilling into the tee. Pour more water onto the tee while drilling as necessary.

Back the drill out once the hole is deep enough into the tee. Hammer a plastic anchor into the drilled hole with a rubber mallet before attaching the fixture.
