## Description

TEHify 1 Inch Wet Diamond Core Drill Bit, 1-1/4" Thread, 14" Drilling Depth, Fast-Cutting Hole Saw for Reinforced Concrete, Block & Hard Masonry - desertcart.com

Review: High quality product for boring through thick, hard concrete and neat job on brick. - Easily bored first hole through 8" of hard concrete foundation with wet boring machine, 5" into second hole I was annoyed with myself for not ordering two as progress slowed considerably. Turns out I had hit 5/8" thick rebar head on, past that it was easier going again. Using the same bit I easily bored another hole through brick for a hose bib. High quality bit and highly recommend.
Review: Very well built. - I needed to drill a 2-inch hole through the edge of our concrete floor in the garage to install a 1 1/2-inch drain for a back-flush filter which runs out under the sidewalk to a 55-gallon plastic drum. I don't have a core drill (that has a water hook-up) so, I had to pour water from a plastic jug on the bit as I drilled. To get the 45-degree angle I made a 2 hole through a 2 x 6 board. When I got a few inches into the concrete, the drill hung up and slapped the crap out of me. Plan B, build a 2 x 4 brace to hold the drill with a little help from a friend. It worked great. What I learned was to drill about 1-inch at a time, pulling the drill from the hole and removing the concrete core as needed, it helped it not to get hung up. I also needed a SDS Plus adapter to go from this core bit to my rotary drill motor. Works great, Be Patient and drill slowly. P.S. when it got hung-up, we used a pipe wrench to back it out.

### ⭐⭐⭐⭐⭐ Great tool
*by D***. on January 7, 2025*

Was perfect for my needs. Needed to purchase the arbor to drive this as a separate item. Worked very well. Note: do not try to rush while using this and will work better if you use some water with it.
