Accupro's pilot bit is designed for precision drilling in various materials with a diameter of 0.25 inches, engineered to create accurate pilot holes in metals or woods using a step-drill bit guide. The cobalt alloy construction delivers exceptional hardness and heat resistance during high-speed drilling while preventing walk-off on the pilot hole center. The spiraled flutes efficiently evacuate chips, maintaining bit sharpness and eliminating the need for frequent re-centering.
