Diablo Metal Demon 1/4" x 4" Stainless Steel Drill Bit with 3-Flat Shank is engineered for serious metalwork, delivering reliable performance when you need clean, accurate holes in steel and other hard materials. The standout feature is a 3-flat shank that locks into the chuck with minimal slipping, providing consistent torque and reducing wandering during setup and drilling.
Designed to tackle deeper holes without frequent bit changes, this drill bit combines a 1/4" cutting diameter with a 2.5" flute length and a 4" overall length. That extra reach is ideal for through-holes in metal panels, automotive work, fabrication projects, and areas where space is tight but hole depth matters.
