Review on Glass Drill Diamond Coated GLS 237 by Jon Dugan

Through trial and error, I found that this diamond-coated industrial drill bit made drilling through glass a breeze. The sharpness and durability of the bit make it quick and easy to use, while the precision it provides is simply remarkable. The only downside is that the bit tends to be a little pricey compared to others on the market. Overall I would definitely recommend this bit for anyone looking for a quality, reliable tool to make their glass drilling projects a success..
