Ideal for hard materials such as metal, glass, gemstones, pearls, and tiles.
We prepared these because customers who purchased mini-routers and micro-drill bits were having trouble drilling hard materials. They couldn't center the drill bit, couldn't use a center punch like on iron, and the drill bit tip would jump, preventing them from drilling holes.
These can also be used for centering and engraving hard materials like glass, tiles, gemstones, and precious stones. The short needle-like tip reduces vibration, positively impacting processing accuracy.
Use these bits to establish the center before using drill bits suitable for your material.
Diamond drill bits with extremely fine tips and straight points have a low pass rate during manufacturing, making highly accurate ones very expensive tools. However, by using water to prevent overheating, you can use them for a long time.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
