Shopkeeper Tips

01：The drill bit requires high-speed rotation, the specific parameters can be obtained from the reference tachometer
02：Due to the particularity of brittleness and hardness of this product, problems such as cracking and fracture during use are not covered (electric hand drill is prohibited)
03：recommend CNC numerical control equipment use (high durability) second bench drill use (improper operation, scrap rate is relatively high)
