The recommended maximum drilling speed for soft cast iron is 150 surface feet per minute (SFM). This value is related to drill revolutions per minute (RPM) by the formula: RPM = SFM x 3.82/drill bit diameter. If you're drilling a 1/2-inch hole, then, the maximum drill speed should be 1,146 rpm, which is about midrange on most portable drills.

Over 300 minerals contain iron but five minerals are the primary sources of iron ore. They are (i) magnetite (Fe3O4), (ii) hematite (Fe2O3), (iii) goethite (Fe2O3.H2O), (iv) siderite (FeCO3), and (v) pyrite (FeS2). The first three are of major importance because of their occurrence in large economically minable deposits.
