The self-drilling hollow anchor system performs drilling, anchoring and grouting in one step. It allows air and water to freely pass through the bar during drilling to remove debris and then allows the grout to be injected immediately after completely covering the entire bolt.
The correct selection of the drill bit dependent on the
geological conditions on site is essential to ensuring a productive and cost-effective installation of the hollow bars. Conventional drill bits are designed for longevity. We offer a wide range of drill bits
suitable for diverse geological conditions.Drill bit adapters increase
flexibility by allowing the use of drill bits designed for other dimensions of hollow bars.
The stability of the drill bits enables safe drilling of the borehole down to
the required depth Since the drill bit is used for one borehole only (sacrificial drill bit), the service life should meet but not significantly exceed the requirements so as to ensure cost-effectiveness)The type of drill bit used and, in particular, the inserts are dependent on the geological conditions on site,
The drill bit diameter is dependent on the design requirements and the
specifications defined in the approvals.
Application
Hardened Steel Button Drill Bit are Designed with tungsten carbide. The "button" design of this drill bit makes it excellent for unconsolidated rock with boulders.
