Review on 🧱 Enhancing Precision & Efficiency with Core Brick Concrete Block Pilot Cutting Tools by Brian Kumar

I need to drill precise holes in 1 inch diameter bricks and this was the best option I found. Unfortunately, what they sent me turned out to be rubbish. This ruined my project and revealed that the pilot drill and possibly the main drill were slightly deformed. I've tried resetting install, water, tried that on a few subsequent bricks to see if I made any user errors, and no. This part was about launching devastating trills each time, destroying a random orbit of about 2-3 cm of upper surface material each time. I even tried drilling a pre-track for the pilot drill to get around the targeting issues and then went as far as making a special clamp guide block for the drill to keep the nasty thing inside and it was still bouncing all over the place place and distort. As if that wasn't enough, on the last try the blue outer hole itself somehow dangerously broke loose from its own threads at the base and caught in such a way that the inner threads were exposed and everything snapped into place. It took 4 broken stones before a full takeover occurred on the fifth. Really unacceptable. I understand quality control things happen sometimes and other than that it looks fine so I'm going back and ordered a replacement to give it a second chance. If they send me one that works this time I will change this review. (Please send it quickly.) If I get another box, this review will get a star because I put even more time into the project. Stay tuned, but avoid this product for now.
