How to use
Mount the Proline 71660 drill bit securely in a compatible drill chuck, ensuring concentric alignment and firm clamping. Select an appropriate cutting speed and feed for the specific metal being drilled, and apply steady, moderate pressure to avoid bending the long shank. Use cutting fluid or coolant where appropriate to reduce heat and improve chip removal. For deep holes, periodically withdraw the bit to clear chips and maintain cutting efficiency.
Usage recommendations
For best results when drilling metal with an extended-length bit, use a rigid drill setup or drill press where possible, maintain correct spindle speed and apply cutting fluid. Inspect the bit regularly for wear and replace it when cutting performance degrades to avoid damage to workpieces or the tool.
