Key specifications

How to use
Fit the Irwin 4 mm twist drill bit into a properly tightened chuck on a hand drill or drill press. Select an appropriate rotational speed for the material being drilled and clamp the workpiece securely. Start drilling with steady pressure, allowing the bit to cut without excessive force. For deeper holes, periodically retract the bit to clear chips and maintain cutting efficiency. When drilling stainless steel or other hard alloys, reduce speed and use coolant to limit heat buildup.
Usage recommendations
Use lower speeds and lubricant or coolant when drilling stainless steel; for wood and plastic choose higher speeds and moderate feeds. Inspect the bit for wear before use and replace when cutting becomes inefficient or the tip is damaged. Secure the workpiece and wear appropriate eye protection during drilling operations.
