RICHELIEU BSHCBG16 HAMMER DRILLBIT 1/2"X4X6

Blue Granite carbide hammer drill bits are for fast impact drilling in concrete, stone and masonry. Low-voltage, high-temperature brazing prevents the carbide cutting edge from breaking out even when head builds up during deep drilling. Milled U-flute and deep-cut spiral single-flute designs are combined with a diamond-ground carbide tip to provide fast removal of drilling dust. Perfect "on-center" diamond tip grinding for fast starts and drilling. Inductive hardening process provides a softer shank for better gripping power.
