Notes

• When installing the drill bit, first check whether the spindle has any swing and if the electrical and mechanical parts are normal. The drill bit should be ensured to be clamped with the drill rig and kept concentric.
• Water must be added during the use of the product. It should be mainly used for core digging works with drill bits. An optional fixed or handheld drilling rig is recommended
• The end of the drill bit with a bottom diameter greater than 89mm/3.5inch cannot be removed.
• It's tested that this product takes about 4 minutes to punch through a cement block with a thickness of 22cm/8inch and four 14mm steel bars inside and can punch through 40 holes. It takes 3-4 minutes for a hand-held drill to punch through a brick wall. (This is only for reference. Different operating conditions will affect the working life of the drill bit.)
