How to use

Use the smallest possible drill bit and appropriate feed pressure for the material to reduce runout and prolong collet life. Regularly inspect collets and clamping nut for wear or damage and replace any worn components. Ensure compatibility with your specific handheld MICROMOT model before use and follow the machine manufacturer's safety instructions.
