3-8x16in Multi-purpose Bit

For rotary or percussion drilling. Chrome vanadium steel shank with cobalt and tungsten carbide tip that withstands temperatures up to 1900 degrees Fahrenheit. Special negative back grinding enables tip to bore through applications such as masonry, ceramic tile, concrete, brick, fiberglass, plexiglass, cast metals, hardened steel, granite, marble, woods, and plastic with a filing action rather than a cutting action. No center punch required; eliminates walking and can be re-sharpened. NOTE: Not recommended for use on mild steel. This includes aluminum, angle iron, copper, galvanized pipe, brass and stainless steel.
