Hilti DD 30-W diamond drill for anchor and rebar applications

Unique diamond drill

For anchor and rebar applications

Hilti DD 30-W drilling system for quick, precise and virtually noise-free coring

Meet the Hilti DD 30-W drilling system for hand-held or rig-based wet core drilling. It not only cuts through rebar with speed and ease, it also lets you drill with exceptional accuracy, even in brittle materials that would suffer damage from hammer drilling. 

Did we mention that it’s quiet? Drill virtually noise-free with the DD 30-W and go places where loud hammer drilling is an issue. Specially designed to dramatically reduce vibration by half compared to hammer drilling and weighing less than 8 kg, the DD 30-W will help you finish your day’s drilling jobs in no time at all.


  • Virtually noise-free drilling
  • Impact-free drilling
  • TopSpin technology for fast drilling through rebar
  • Part of an approved system solution for anchoring in diamond-cored holes


  • Structural reinforcements and upgrading 
  • Post-installed anchors for structural steel
  • Installation of architectural metal components, e.g. handrails or decorative ironwork
  • Crash barriers, noise barriers and structural extensions on heavily reinforced concrete
  • Installation of heavy pipes and machinery


  • Powerful and precise: the DD 30-W drills through a wide range of materials with ease – from heavily reinforced concrete to fragile tiles, marble or masonry
  • The ideal solution for renovation work in inhabited buildings, hospitals or areas where noise must be kept to a minimum
  • Soft-start function for smooth hole starting and less risk of damage to core bits 
  • New SPX-T line core bits for extra-high performance and longer lifetime

Topspin Technology

Stay on top of your game with the new Hilti DD 30-W

Finish up to 300% quicker than with conventional diamond tools, thanks to DD 30-W's exclusive TopSpin technology. 8700 rpm combined with slightly eccentric rotation of the core bit transfers pressure more effectively to the diamond ring, which results in faster drilling. TopSpin makes it easier than ever to cut through tough rebar and reduces the contact pressure required to drill through heavily reinforced concrete by half.
