A body of a cutting tool may include a shank and a tip having spaced-apart, helical flutes. Each spaced-apart, helical flute may include a helical cutting edge extending from a tip bottom, adjacent a shank top, to a tip top. The tip may include chip gash paths. Each chip gash path may be recessed between two of the spaced-apart, helical flutes, and extend from the tip bottom to a tip top portion. The body may include helical coolant channels extending from entrances at a shank bottom, to within a shank interior, to within a tip interior, to tip coolant orifice exits. The coolant orifice exits may be disposed in the spaced-apart, helical flutes adjacent the chip gash paths or disposed in relief surfaces extending from the tip top downward to the chip gash paths. The coolant orifice exits may be spaced-apart from the tip top.
