Minova MAI SDA self-drilling anchors
Product catalogue
Minova Rock ReinforcementOngoing development of faster, safer and more exotic tunnelling techniques places a constant pressure on manufacturers to provide more efficient rock support solutions which will help the shortening of cycle time. As ground conditions get more and more demanding, emphasis is placed on flexible and intelligent support systems in which rock and soil reinforcement is expected to con-tribute to the productivity and safety of the operation. The trend has been to provide rock support and reinforcement systems that are easy to install, assure efficiency and provide safety.
The Minova MAI SDA self-srilling anchor is today’s answer to the increasing demands of the tunnel-ling industry and ground engineering for safer and faster production. The system provides advan-tages for all areas of its applications, where boreholes would require the time consuming drilling with casing systems in unconsolidated or cohesive soil.

MAI SDA self-drilling anchors
Minova MAI SDA self-drilling anchors provide a unique bolting solution for unstable ground conditions such as sand, gravel, silt and clay, and in soft to medium fractured rock formations. For projects facing such ground conditions, MAI SDA self-drilling anchors should be considered as the most productive reinforcement solution.
The anchor rod features a hollow bore for flushing or simultaneous drilling and grouting, and has a left-hand rope thread for connection to standard drill tooling.
It is manufactured from API standard heavy wall-ing steel tubing, cold rolled to form a standard ISO rope thread profile. The rolling process refines the grain structure of the steel, increasing the yield strength, and producing a durable drill rod suit-able for a range of applications.
The sacrificial drill bit is the most crucial part of the anchoring system, and is responsible for the productivity of the installation. In order to im-prove on performance and cost efficiency, data is collected from projects around the world, and incorporated into the design with the aim to improve penetration rate and bit quality, and to reduce manufacturing costs. Minova MAI SDA self-drilling anchors are rigorous-ly tested to ensure the best quality and reliability.
MAI SDA self-drilling anchors also available in a hot dip galvanized version for corrosion protec-tion and also as CE certified products.
Main components
MAI SDA self-drilling anchors consists of five basic components:
• A hollow rod• One or more extension couplings which act as
connectors between the rods• A sacrificial drill bit• A nut and• A plate

Main selection criteria for MAI SDA drill bits
A successful installation of Minova MAI SDA self-drilling anchors depends to a large extent to the correct selection of suitable drill bits. Compared to conventional drill bit types offered globally for maximum standing performance for rock or soil, the criteria for MAI SDA drill bits are defined by consideration of the following factors:
• Service life of the drill bits should be at least equal to the anchor length.• Selecting the right bit design and inserts to reach optimum performance depended on the differend
ground formations encountered.• Diameter depending on geology and design requirements.
