The HCI Self-drilling Anchor employs the fully threaded Hollow Bar manufactured by machines and technology imported entirely from the European IBO Self-Drilling System.The Hollow Bar is cold rolled to form standard rope thread. The rolling process refines the grain structure of the steel, increasing the yield strength and producing a robust hollow bar acting as both drill rod and grouting tube during installation.
Comprising of the Hollow Bar, drill bit and other fittings, the HCI Self-drilling Anchor can enable the hole drilling and grouting to be done in one single cycle without the use of casing.The whole anchorage components of HCI Self-drilling Anchor have been all successfully produced locally in Taiwan since the machines and technology imported. With our effort, HCI Self-drilling Anchor is not only a popular products in Taiwan, but also a constantly inquired products to countries such as Austria, Japan, etc.

Main Advantages
▪ Drilling, installation, and injection the HCI anchor in one single operational cycle
▪ Easy and same operating principle for different rock mass and soil conditions
▪ No need for pre-drilling of a borehole, saving the time for removing the casing and the drill rod
▪ Especially suitable for unstable geology where borehole collapse is expected
▪ Minor working space required and can be installed by small drill equipment
▪ Easy step of extension to the designed anchor length by coupling
▪ Variety of designed drill bits and diameter for fulfilling different geology
▪ Hollow bar can be used as air and water passage during installation and increase the bonding by additional grouting inside.
▪ The quality of HCI Self-drilling Anchor is guaranteed by HCI high quality contro
