Installation & Use Guide

Step 1 – Choose the Correct Size
Select the drill bit size that matches the diameter required for your project.

Step 2 – Install the Drill Bit
Open the drill chuck, insert the drill bit shank straight into the chuck, and tighten it securely before use.

Step 3 – Mark the Drilling Position
Clearly mark the location where the hole will be drilled. Make sure the workpiece is stable and properly secured.

Step 4 – Start at Low Speed
Place the drill bit against the marked position and begin drilling at a low speed to help prevent slipping.

Step 5 – Apply Steady Pressure
Keep the drill as straight as possible and apply moderate, even pressure. Do not force the bit into the material.

Step 6 – Adjust Speed as Needed
Increase the drilling speed gradually depending on the material. For glass, tile, stone, or other hard materials, use a slower speed and appropriate cooling when necessary.

Step 7 – Remove and Clean
After drilling, stop the drill completely before removing the bit. Clean away dust and debris and store the drill bits in a dry place.

Usage Notes

Always wear appropriate eye protection and work gloves when drilling. Confirm that the drill bit, drill chuck, drilling speed, and workpiece material are compatible before use. Avoid excessive pressure or overheating, as this may shorten the service life of the drill bit.
