It can be used multiple times, and it is convenient and quick to change the wheel. The roller is divided into three types of A type, B type and C type, and different diameters of reaming can be realized through adjustment.
The unique multi-stage anti-disengagement interlocking device prevents the hob from tripping when the drill bit is empty, and prevents the hob shell from falling off when the bearing is damaged.
The roller body is inlaid with a large-diameter hard alloy, which has a good rock-breaking effect; the bearing diameter is large, and the impact resistance is strong; the metal seal is used, and the service life is long.
