💎 Ultimate Precision: Hitachi 728024 32 Inch Diamond Core - Enhancing Drilling Efficiency Review

This industrial drill bit is an absolute game-changer. It cuts through even the toughest materials with ease and lasts for ages. The diamond core ensures that it stays sharp, giving it an exceptionally long lifespan compared to other drill bits on the market. However, the price might be a bit hefty for some. Overall, a fantastic investment for any industrial and scientific cutting tools collection.

Used for drilling porcelain stoneware for installing a shower door. Paused every 20 seconds and dunked in a barrel of cold water to avoid overheating. Used a small nail to pry out the stuck chips. I cut the first 6-8 holes like nothing happened. He started to slow down on the 10th hole. Your mileage may vary, but this exceeded my expectations. Just remember to start the drill at an angle and slowly tilt the drill straight back as it pierces the glaze of the tile. I will buy it again!

I bought this drill bit to drill through some ceramic tile that was already installed in my shower. Each hole lasted several minutes. I stopped about every 15 seconds to wet the bat and tiles to prevent excessive heat build-up. I probably didn't have to stop as often, but I'd rather be overly careful than risk breaking the tile. I have now safely installed the curved shower curtain rod and my wife is delighted. If I ever need to drill tile again I will definitely buy one of these drill bits…
