3 and half inch core drill bit

3 1/2" core drill bit. Wet USE only. 1 1/4" x 7 tpi arbor thread. Used to core drill heavy cement or reinforced concrete walls, floors or block walls. Weight 6.05 lbs. Laser welded segmented teeth for longevity and toughness. A favorite bit of hand railing companies which set 2" x 2" aluminum or steel posts.

We used this very same type bit on many projects along the east coast. 

Here is one of us core drilling a 3 1/2" hole in a curb near Raleigh, NC.

As you can see we used our truck tire like a roof jack to hole the core drill rig in place as we drilled the hole.


Below we are using a 3 1/2" core drill bit (with an extension) to drill through the concrete footer under the brick wall.

Core Drilling involves many support tools. It is neccessary to have a core drill wrench usually 1 3/8" in size, and a plumbers pipe wrench to change your core drill bit or for removal.
