Self-Drilling Anchors
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 grout to be injected immediately after completely covers the entire bolt.
Self-drifting anchor consists of:
