The automatic center punch has a heavy-spring action, and you simply place the tip where you want to drill, and it punches a slight indentation in the surface. Just enough so that the drill bit won’t walk
• 【118° Split Point】：These step drill bits have a small point angle of 118° and require less pressure when centering in the material. The point starts drilling at contact, reducing friction, pressure, and heat. The larger the point angle, the higher the contact pressure and the centering in the material requires more pressure
• 【Double Flutes & Tri-Flatted】：These drill bits feature a special dual flute straight design for dependable performance and durability. And the shanks on these step drill bits have three flats that help prevent the bits from slipping in the drill chuck during drilling
