How to use
Select the required drill diameter for your task and secure the workpiece. Use a low to moderate spindle speed appropriate for small-diameter HSS drills and ensure steady feed to avoid breaking the bit. For printed circuit boards and delicate materials, use light pressure and consider backing the board to prevent splintering. Replace worn bits to maintain drilling accuracy.
Usage recommendations
For best results, use appropriate holding tools (pin vice or micro-chuck) and start holes with a center punch or pilot mark when possible. Keep the bits clean and store them in the supplied box. For metal and hard materials, apply cutting oil sparingly to improve tool life; for plastics and PCBs, avoid excess lubrication.
