【Automatic Center Punch】: The automatic center punch provides a strong, spring-loaded, automatic impact on the cap; its brass body has a deep knurled surface for a non-slip grip. The protective aluminum case offers convenient storage and transport.

【Double Cutting Blades and Tri-Sided Shafts】: The double cutting blades and X-shaped opening design ensure faster and smoother cutting; the 3-sided shaft design prevents the drill chuck from slipping; With minimal pressure, the set can cut wood, sheet metal, steel, and other surfaces. [HSS AND TITANIUM COATING]: High-speed steel makes the step drill bit set more durable, and the titanium coating can easily cut steel, aluminum, copper, plastic, wood, and many other types of sheet metal. [TIME SAVING]: Covering a variety of pitch sizes, you can drill or enlarge different holes with a single drill bit without constantly changing bits. The dimensions are laser-engraved into the metal so they can be drilled precisely and won't wear down even with prolonged use.
