How to use

Install the Irwin 4.8 mm twist bit into a compatible drill chuck and tighten securely. Select an appropriate drill speed and feed for the material: higher speeds for wood and plastic, lower speeds for metals. Use steady pressure and keep the drill perpendicular to the workpiece to achieve a clean 4.8 mm hole. For through-holes, back the drill out occasionally to clear chips and prevent clogging.

Usage recommendations

When drilling stainless steel or other hard metals, use coolant or cutting fluid and reduce speed to prevent overheating. For thin sheet metal, support the workpiece to avoid distortion and use a sharp bit. For plastic, use moderate speed to avoid melting; for wood, pilot holes or stepped drilling can improve accuracy when necessary.
