How to use
Select an appropriate drill speed and clamp the workpiece securely to prevent movement. Fit the Proline 90416 bit into a compatible chuck and ensure it is tightened concentrically. Begin drilling with steady pressure; for thin materials, use low to moderate feed to avoid distortion. Clear swarf periodically and, when drilling thicker sections, withdraw the bit occasionally to remove chips and cool the cutting edges. Finish holes with a deburring tool if necessary.
Usage recommendations
Use cutting fluid or coolant when drilling thicker or harder metals to extend tool life and improve cutting performance. Ensure correct drill speed for the material and maintain secure clamping of the workpiece to achieve accurate, centered holes and to reduce the risk of breakage in small-diameter bits.
