The Diablo 1-1/8″ x 1/4″ Step Drill Bit DSD1125S17 is engineered for electricians, plumbers, and HVAC contractors, offering fast, accurate cuts and enhanced stability in thin metals, PVC, and other plastic materials. Its innovative split point tip (132°) eliminates the need for pre-drilling, resulting in increased speed, maximum durability, and up to 6 times longer life. The automated precision CNC grinding process ensures strict angle tolerances on each step, leading to minimal bit wear and twice the cutting speed in drilling and hole-making applications. Designed with a 1/4″ hex shank, this bit is impact-ready and compatible with both drills and impact drivers. The optimized dual flute design provides jam-free cuts, while laser-etched step markings allow for easy identification of hole sizes. Ideal for drilling in metal (up to 1/8″ thickness), PVC, and other plastic materials, this step drill bit is a versatile addition to any professional’s toolkit.
