These straight-flute drill bits have a bright finish that is unaffected when the bits' cutting edges are resharpened. Carbide-tipped drill bits have carbide cutting edges that provide excellent hardness, wear resistance, and heat resistance. The bits' body is made from a material that absorb more vibration and shock than carbide, so they are less rigid and less likely to break than solid carbide drill bits. These bits are used in machine setups.These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling.
