Anyone who’s ever used a combi-hammer to drill through concrete with rebar knows what a tiring process it can be. Beyond the vibration traveling up the tool rattling most of the bones in your upper body while you push through the concrete, to get through the rebar you need to switch over to a drill to get through the rebar, and then back to the combi-hammer to complete the hole.
Designed to make the task of setting adhesive anchors in concrete with rebar much faster and quieter, Hilti has introduced the DD 30-W diamond coring rig. The company introduced the tool earlier this summer and demonstrated its capability at its annual Innovation media event in Dallas on Tuesday.
Hilti demonstrated the DD 30-W beside the traditional setup described above. After setting the DD 30-W atop the designated mark and turning it and the DD-WMS 100 water management dust suppression system on, all that was required by the demonstrator was to place a foot on the back of the rig and bear down on the front as you would with a combi-hammer.
The DD 30-W operated quietly while the demonstrator with the combi-hammer rattled along. And the DD 30-W completed its hole before the demonstrator with the combi-hammer could even switch to the hand drill to get through the rebar.
Hilti says the DD 30-W is designed to set adhesive anchors five times faster. And because of its quiet operation, it can be used in inhabited buildings like hospitals, commercial and residential buildings.
When used in combination with the DD-WMS 100, 30 gallons of water is recycled up to 7 times for up to an entire work day. The system captures slurry in its filter bag making disposal as easy as dumping it in the trash.
The DD 30-W is backed by Hilti’s 20/2/1 year warranty – 20 years of repair or replacement of defective parts; 2 years no cost repair including wear and tear; and a guaranteed 1-day turn-around on repairs (conditions apply).
