Review on 💪 Unleash Your Inner Strength: Introducing BEDSIFV Ultimate Triangular Punching Concrete by Sirious Cavalli

To be honest I haven't tried using them to drill holes in glass but they definitely work with tiles that went through with no problems The trick is to do it slowly at first and add water to to cool the drill bit when drilling.Smooth U-grooves help remove chips faster and the drill is smoother.The triangular cutter head is sharp since it's the first time to use it,but I think it should be ok and last a long time , as it is made of Durable Carbide also helps prevent slippage when drilling All these factors wear n addition to the production of these high-quality bits. They seem very valuable to me so I'll probably just keep them for drilling mostly tile and on rare occasions metal. I have other wood drill bits so it's not such a big deal. One day if I have the courage I will try to drill glass with these bits :).
