How to use
Select an appropriate drill speed and feed rate for the metal being machined and secure the workpiece before drilling. Fit the Proline 71834 into the drill chuck and ensure it is tightly clamped and concentric. Use cutting fluid or coolant as recommended for the metal type to prolong tool life and improve chip removal. Apply steady pressure, allow the bit to cut without excessive force, and periodically withdraw the bit to clear chips when drilling deep holes.
Usage recommendations
For best results in steel and other ferrous metals, use medium to low spindle speeds with consistent lubrication and moderate feed. Inspect the bit for wear or damage before use and replace if cutting performance degrades.
