Published by [Steven Oszust Jr.](https://blog.fullertontool.com/author/steven-oszust-jr) on July 20, 2022 Ever wondered about the advantage of a three-flute drill over a two-flute drill? Adding a third cutting edge to drills for higher feed rates is nothing new, but the benefits don't end there. Three-flute drills produce smoother, rounder, and straighter holes compared to two-flute drills. The drill's three margins help keep it centered and eliminate the wandering you get with a two-flute drill. With three-flute drills, you can also expect a hole that's nice and straight, with a reamer-class finish. The tool's ability to resist deflection when encountering cross-holes in angled surfaces results in greater hole accuracy, improved tool life, and up to 50% higher speed with an increased part count. A three-flute drill's power and torque requirements are roughly 60% that of a two-flute drill. Now that's a lot of benefits compared to a two-flute drill!  ![3-Flute-Drills](https://blog.fullertontool.com/hs-fs/hubfs/3-Flute-Drills.png?width=757&name=3-Flute-Drills.png) Ready to join the three-flute bandwagon?
