Revolutionary performance

Hilti DD EC-1 diamond coring system

Hand-held diamond coringsystem for drilling anchorholes and through holes.Features unique TopSpintechnology for an entirely newlevel of performance and easeof use.

Perfectly drilled holes for HVZ, HVA, HSL-TZ,HST, HSA, HKD-S and HRD anchor systems

CleanNo dust, no dirty water: The built-in drillingslurry extraction system makes unrestricted usepossible even in sensitive surroundings wherespecial precautions would otherwise have to betaken. Costly, time-consuming cleaning up aftercompleting the job becomes a thing of the past.

Hilti TopSpin technology for top productivity

Calculable costsUnique software: Calculate time requiremand the number of core bits necessary fojob, taking into account the material in wthe holes are to be drilled and the numbereinforcing bars expected to be encounte

VersatileThanks to the new Hilti DD-C core bits andTopSpin technology, the DD EC-1 drills throughvarious types of steel reinforced concrete,marble, sandstone and tiles with the same single speed setting for all diameters.

Through holes of up to 35 mm diameter forvarious applications

RevolutionaryThe Hilti DD EC-1 diamond coring systemmarks the beginning of a new era. Itsunique TopSpin technology, a world first,sets completely new standards in drillingperformance and ease of use.Precise anchor holes and through holesof 835 mm diameter can now bedrilled neatly and tidily almost any-where. The Hilti DD-REC1 mobilewater recycling unit filters the usedcooling water before returning it to theclosed-circuit system.It's time to start thinking in a newdimension, because Hilti has re-invented diamond coring, making itquicker, more efficient and more eco-nomical than ever.

ConvenientEasy core removal: The open end of the core bitand a special core breaking tool make life easyfor the operator.

Economical and environmentallyfriendlyThe unique water recycling unit, a world first,uses up to two-thirds less water than conven-tional systems. Also equipped with a containerto facilitate environmentally correct disposal ofthe drilling slurry.

AutomaticElectronic water management: The pump andextraction function are activated / deactivatedautomatically by the drilling machine controlswitch. The operator simply regulates the waterflow rate, as necessary.

MobileTake it anywhere: The Hilti DD-REC1 ensuresmaximum mobility and flexibility on the jobsitethanks to almost total independence from exter-nal water supplies. It comes complete with apractical trolley for easy transport.

Hilti DD-REC1: Water power!

Diamond coring with unprecedented mobility and flexibility Drills cleanly, causing no dust

TopSpin: The future of diamond coring

The unique TopSpin principle is based ona slightly eccentric movement of the corebit. Pressure is transferred selectively topart of the diamond ring, thus causing thediamonds to cut into the material moredeeply and more effectively. Especiallywhen coring through reinforcing bars, HiltiTopSpin technology in conjunction withthe high speed of 8000 r.p.m. sets newstandards in diamond coring performanceand efficiency.
