【Extra Automatic Center Punch】：You know how when you try to drill into metal or hard surfaces and your drill bit "walks" no matter how much you think it's steady? Yeah, we have a tool for that. 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.

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 f....
