Hyper Step Drill Bit, 4.5mm

Features and Benefits

New patented Hyper-Step tip design cuts 45% faster and excels at sheet metal and hardened metals like broken fasteners.
Spread the job of cutting across multiple levels, staying sharp up to 4X longer compared to conventional and other specialty tip designs.
The multi-stepped tip acts like a step drill, allowing for laser like holes through sheet metal and prevents walking on curved surfaces.
Three-flatted shanks to reduce slippage common with keyless chucks.
Eliminates the need to drill starter pilot holes before making larger hole sizes.
