Secure the Tool Properly: Make sure the tool is properly secured to prevent any unnecessary movement during use. This can be done by using a vice or clamp to hold the tool in place.
Use Correct Technique and Angle: The DHR242 should be held at a slight angle when drilling, instead of being pressed directly against the surface. Using an incorrect angle can cause the tool to vibrate excessively.
Inspect for Wear or Damage: Excessive vibration and movement can also be caused by worn or damaged parts. Inspect the tool regularly and replace any parts that show signs of wear or damage.
