1-9/16" Diam, 4 Flutes, Morse Taper Shank, Interchangeable Pilot Counterbore MPN:251650

This high-quality 4-flute drill bit has an impressive diamond coating for extended lifespan and features the Morse Taper shank, enabling direct shank fitment in drill presses or lathes while reducing chattering. The counterbore reduces back-out prevention as it simultaneously creates an indent for headed screws to fasten onto a material. With interchangeable pilots, you can quickly change the diameter size for varying holes on multiple tasks, and this 1-9/16-inch version offers excellent performance in machining metals such as aluminum, steel, or stainless steel for general maintenance, repair or manufacturing works.
