Features:
This product is a brazed hole opener set, which is used to make holes in tiles, marbles, etc., and is a hole-opening tool accessory.
Emery grinding surface: The drill bit grinding surface is made of emery. The emery is electroplated and quenched at high temperature, which has high hardness, sharpness and durability.
Integral forging: The drill bit has undergone an integral forging treatment, which makes the overall structure of the drill bit more stable and solid, and there will be no chattering when drilling.
Solid cooling wax: The inside of the drill bit is treated with sealing wax, which can cool down to a certain extent during the drilling and cutting process, realizing the function of dry driving, so that the drill bit can be used for a longer time.
Universal round shank: The shank of the drill has a round design, which makes it suitable for most electric drills and angle grinders.
