- Safe and durable: robust steel construction with high wear resistance ensures stable drilling, longer tool life, and lower operating costs through efficient performance. - Versatility and portability: multifunctional performance in a compact package and a custom storage box to protect and organize the precisely graduated drill sizes, preventing damage or loss. - Optimized heat management: the stepped drill body enables intelligent heat dissipation, preventing heat build up and preserving the bit edge for consistent high performance. - Modern cutting technology: layered cutting design with four stage geometry reduces cutting resistance, enabling higher drilling speeds and clean edges without burrs. - Use on metal, aluminum, and plastic: create progressively larger holes in thin sheets with a single drill pass and minimal tool changes. - Enlarge and deburr: quickly enlarge existing holes and smooth edges in sheet metal for a precise fit of fasteners or components. - Practical for trades: ideal for electrical, HVAC, and cabinetry work where multiple hole sizes are needed with reliable performance and easy organization.
