This Step Tip Hole Saw Arbor Range provides a reliable connection between compatible bi-metal hole saws and power drills, with two arbor sizes covering hole saw diameters from 14mm through to 250mm. The step-tip pilot drill supports fast, accurate starting without requiring a separate pilot hole and helps produce clean, round holes with minimal burring.
Each arbor uses an international-standard thread pattern compatible with common hole saws. The fully ground premium M2 high-speed steel pilot drill is designed to reduce heat, retain sharpness and provide extended service life when cutting steel, timber and plastic. The small arbor features a quick-change shank, while the large arbor uses a heavy-duty screw-up design for larger hole saws.
