Hilti is a specialist for a wide range of applications in the field of construction worldwide and a competent partner for concrete coring and sawing service contractors.

The company has supplied coring machines and diamond core bits since 1982 and service contractors from the concrete coring and sawing trade have purchased equipment from Hilti's own range of wall saws and blades since 1988.

Gearmec of Sweden, a company well-known for its solidly-built and innovative wall saws, was taken over by Hilti in 1992. Since then, the range of products offered has been optimised and expanded continuously. Today, it extends from coring systems of various types to a range of very easily operated, high-performance wall saws and wire saws as well as the appropriate diamond core bits, blades and wires. These products have all been developed by Hilti and are thus highly innovative.

Hilti's own specialists

In order to meet the requirements of service contractors, Hilti has established special departments at its headquarters in the principality of Liechtenstein and in the national marketing organisations.

Professionals from the concrete coring and sawing trade can thus rely on competent support from Hilti's own diamond coring and sawing specialists. These teams of experts assess the special requirements of customers in this field, develop and manufacture the appropriate equipment, core bits, blades and wires and provide a range of services that meet the needs of the trade.

Coring systems

No matter whether drilling anchor holes or large openings, Hilti diamond coring systems provide the performance, operating convenience and reliability needed for coring applications of all kinds.

Hand-held machines and rigs designed on a modular concept ensure great versatility and open up possibilities in countless applications.

Wall saws & wire saws

Hilti's outstanding wall saws and wire saws are renowned for their power and performance. The machines available range from the very handy electric wall saw - representing a milestone in wall sawing technology - to the world's most powerful hydraulic wall saw. During development of these systems, great attention was paid not only to power and performance but also to convenience and ease of operation. A range of optimally matched diamond saw blades and wires is also available for these machines. The diamond saw blades, featuring exclusive short-tooth technology for exceptionally high cutting performance and long life, are a particularly notable innovation.

New standard

The DS-WS15 electric diamond wire saw is a versatile system for almost every application, powerful, reliable and extremely quiet for maximum wire sawing cost-efficiency. With the DS-WS15 providing the ability to tackle an almost unlimited range of applications comfortably, conveniently and with maximum efficiency, the technical demolition business takes on entirely new perspectives.

The wire saw has no limits. It cuts openings of all kinds and almost any shape in structural components of all thicknesses and in virtually any situation and saws anything from heavily-reinforced concrete to metre-thick stonework.

It can do angled cuts, flush cuts, dry cuts and plunge cutting. It can be used in underwater applications, technical demolition, removal of foundations, chimneys, and for applications using releasable, plunging and vertical-cutting pulleys as well as circular wire sawing.

Optimum system efficiency is ensured by two electric motors that permit smooth starting even in the most difficult situations and up to 22 kW peak power and 15 kW effective continuous power rating with minimum water cooling, requiring only a 32 amp power supply.

The wire saw is quick, quiet and simple to operate. It has pneumatic controls for smooth saw advance and once set, saws automatically. It has a very simple, quickly-rigged wire storage system, saws through components with a thickness of 4 m in one operation, while the quickly adjustable, high-grade pivoting wire guide pulleys ensure extremely quiet, precise running.

It can be transported in a van and set up extremely quickly. Simply mount the pulley stands and rig the wire, connect the cable set between the drive unit and control unit and start sawing. It is easily understood by operators and safe, has few accessory items, and is easy to clean.

To ensure best possible support to concrete coring and sawing service contractors, teams of specialists from Hilti's marketing organizations are on hand in Germany, Austria and Switzerland. They offer rapid assistance, a constantly high level of product availability and comprehensive service - always with the objective of ensuring that customers benefit from maximum productivity and reliability at all times.
