Review on Efficient Universal Drilling Thickened Accessory by Gerardo Graham

This accessory didn't live up to its promise... After i put it to the test, it was nowhere near as efficient as advertised. it wasn't able to drill through thick materials like it claimed it could and it ended up breaking halfway through the job. The only pro is that it did fit my drill, but thats about it. Save your money and invest in a different industrial and scientific cutting tool..
