Product Description

Rock Drill HOB Hole Opener

Standard Size Sealed Bearing Rock Drill HOB Hole Opener


The body can be used many times, and it is convenient and quick to change the hob wheel. The hob wheel is divided into three types: A, B, and C, which can be adjusted to achieve different reaming diameters.
The unique multi-level anti-off interlock device prevents the hob from tripping when the drill bit is empty and the hob shell falling off when the bearing is damaged.
The hob wheel 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.
