Bosch Blue Granite Drill Bits Review

Blue Granite – now that’s a name that instills confidence. Bosch was going for the manly persona when it came up with that one (but what else should we expect from a German company?). Carbide hammer drill bits are for made for one thing: fast impact drilling in concrete, stone, or masonry. Low voltage, high temperature brazing prevents carbide cutting edge from breaking out even when heat builds up during deep drilling. Various usable lengths up to 10″.
