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)
