- 【C-Profile Design】EZARC step drill bits feature a triple-flute design for increased stability, effectively reducing deviation during the cutting process. Additionally, the 'C-profile' cutting edge ensures smoother cutting and an increased cutting speed

- 【AlTiN Coating】Step bits coated with aluminum titanium nitride, rated at 89HRC for exceptional hardness and thermal properties. This coating offers superior resistance to heat, wear, and corrosion, with high adhesion and low friction
- 【Nine Step Sizes】Spiral flute design, featuring nine distinct steps, offers seamless and effective drilling across various thicknesses, eliminating the need for multiple bits. Includes 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4"
