Precautions
When drilling, water must be dripped (or the stone must be soaked in water) to cool the needle, and there must be water flowing into the drilling needle! The splashing water will form splashes and spray around, indicating normal needle insertion! High (above 20000 revolutions per minute) stable, do not shake, cooperate with lifting and grinding, table grinding, speed control small table (mind using a table drill) You can use pliers to subtract a little bit from the head, which can prevent slipping Continuous addition of water to cool down and apply appropriate pressure is required, as excessive force can cause the needle to break

Product Description: Used in conjunction with high-speed bench drills, drilling drills, electric grinders, and drilling machines. It can drill holes for jadeite, agate, cobble, Hotan Jade, sapphire and other gem and jade materials.

Usage: Do not use a force exceeding 1KG to press down the needle, as the rod is relatively thin! Too much force will break the needle!
It is recommended to use the chicken pecking rice style needle, inject for a period of time, then lift the needle and press it down again! Non fixed machines (such as drills, grinders, hoists, etc.) should consider whether they can be clamped! Due to the inability of non fixed machines to ensure vertical and horizontal downward force, the rod should be clamped as deeply as possible! To avoid shaking the needle! Non fixed machines (such as drills, grinders, hoists, etc.) must not exceed a drilling speed of 6000 revolutions per minute! Because the drilling speed is too high and centrifugal force can shake the needle
