Alpha Munitions’ Legacy drill is designed for pre-drilling chambers before using rougher reamers or chamber reamers, ensuring a precise starting point for chambering. Made from solid carbide, the drill is significantly stiffer than steel, reducing deflection during drilling for enhanced accuracy and consistency. Its precision-engineered drill geometry optimizes cutting efficiency and maintains tight tolerances, critical for high-performance rifle chambers. The Legacy drill’s robust construction and design make it an essential tool for gunsmiths aiming for superior chamber alignment and finish. 0.31" x 3.75" Drill is for use with .223/5.56 diameter/length cases.
