500mm Reamer Bit HDD Hole Opener For Hard Rock Drilling
HDD Hole Opener Reamer Bit Hole - Opener For Hard Rock Drilling
Introduction
The reaming bit is mainly composed of more than 3 cones. The cutting structure adopts high-quality tungsten carbide cemented carbide inserts for surfacing welding, which adopts new technology and new formula, and improves the wear resistance of the reamer.
1. Main size: general drill diameter: 311mm, 346mm, 500mm, 800mm, 900mm, etc., various sizes can be customized
2. Purpose: In the construction site and bridge construction, the hole opener can expand the small well hole to large diameter. Highway construction, railway construction, etc. The drill bit is suitable for different complex formations, shale, limestone, pebbles, etc.
3. Cutting structure: The hole opener always has multiple cones. The drill bit cone is separated from the tri-cone drill bit and welded to form a large-diameter drill bit, and the pilot device is connected with the hole opener.
