R32S Anchor Tool Self Drilling Anchor Bolt Threraded Bar Anchor Rod
Self-Drilling Anchor Tools: The self-drilling hollow bar anchor system consists of a hollow threaded bar with an attached drill bit that can perform drilling, anchoring and grouting in a single operation. The hollow bar allows air and water to freely pass through the bar during drilling to remove debris and then allow grout to be injected immediately after drilling is completed. Grout fills the hollow bar and completely covers the entire bolt. Couplings can be used to join hollow bars and extend the bolt length while nuts and plates are used to provide the required tension.
Self-drilling hollow bar anchor system is the most common used system for rock mass stabilization, especially in tunneling, underground mining and ground engineering industry. It is mainly used for the supporting engineering in the loose and broken rock stratal with difficult to drilling hole. It provides the optimal solution for soil nailing, lock bolting, micro-piling.
Self-drilling hollow bar anchor system fulfills current and increasing demands of the tunneling, mining industry and ground engineering for safer and faster production. The system provides advantages for all areas of its applications, where boreholes would require the time consuming drilling with casing systems in unconsolidated or cohesive soil.

Anchor bolt
Anchor bolt means a rod that transfers the structures or geotechnical load to a stable rock
formations, it consists of rod, drill bit, coupling, plate, grouting stopper and nut. It has been
widely used in tunnling, mining, slope stabilization, tunneldiseases treatment and roof supporting
of undergroundworks. It is for loose ground(clay, sand friable etc.) Hollow anchor rod is made of
seamless tube with high strength.
Features of hollow grounting anchor bolt
• Particularly suitable for difficult ground conditions.
• A high rate of installation since drilling, placing and grouting can be performed in one single operation.
• Self drilling system eliminates the requirement for a cased borehole.
• Installation with simultaneous drilling and grouting possible.
• Easy installation in all directions, also upwards.
• Suitable for working in limited space, height and in areas of difficult access.
• Simple post grouting system. • Hot-dipped galvanizing for corrosion protection
Applications in Tunneling & Ground Engineering
• Radial bolting
• Slope stabilization
• Forepoling
• Micro injection pile
• Face stabilization
• Temporary support anchor
• Portal preparation
• Soil nailing

blast furance tap hole drill rod drill bar drill bit
A drill rod, for blast furnace taphole drilling consists of a steel tube, with a drill tip welded to one end, the novelty being that the drill tip consists of two or more steel profile sections uniformly distributed about the steel tube periphery, the sections being fixed to the tube by weld seams and projecting beyond the tube end by a distance in the direction of the longitudinal axis of the tube.
A tool for blast-furnace tap-hole drilling involves body with a cutting component, enlarging bit, drill rod with cutting structure, which longitudinally is disposed inside the hollow body with a cutting component, and device for control of drilling rod length, placed on a body above the cutting component.
