All about Hilti wall chasers

This article covers everything you need to know about Hilti wall chasers. A general overview of models for concrete, with and without a vacuum cleaner, is given, the subtleties of choosing discs and brushes for a chasing cutter are described, and recommendations for use are given.

When characterizing Hilti wall chasers, it must be emphasized that, in general, they are quite powerful devices. As long as they are not worn out, heavy dusting is not typical for them. The work is proceeding very quickly, even on significant volumes, both for concrete and brick. But individual problems can also arise: breakdowns of dust extractors, jamming of skids. Also, you will immediately need to take into account that such products are very expensive, in accordance with their quality. Hilti technology is rightfully included in the ratings of the best wall chasers.

Above all, attention is drawn to the smart hand-held furrow cutter DCH 180-SL. It is capable of making grooves up to 6 cm deep. Important technical parameters:

• the greatest width of the track to be laid - 6 cm;
• disk section - 18.5 cm;
• own weight of the tool - 9.2 kg;
• automatic regulation of output power;
• user-friendly design that minimizes operator fatigue, even during the most challenging jobs;
• the most verified accuracy of the cut;
• suitability for work on concrete, brick and silicate blocks.

The DC-SE 20 is highly regarded by connoisseurs for its versatility. This model allows cables and pipes to be laid in a wide variety of raw materials. Its maximum slot width is 4.6 cm. The disk section is 12.5 cm, and the net weight of the tool itself is 6.9 kg. Due to the high structural strength and reliability of execution, you can confidently take on even the most complex manipulations.

But Hilti is not only able to offer the furrowers themselves: there is also a special tool for them. For example, SP-SL Universal diamond blades give very good results. The device is capable of working with:

• concrete;
• natural stone;
• brick.

The high speed of formation of the groove is achieved due to the increased concentration of diamonds on the surface of the disk. Since the steel base is reinforced, and special laser soldering is carried out, the stability and reliability of use are ensured.

This is a SPX-SL Universal broad spectrum disc. He:

• copes with the same concrete, natural stone and brick;
• acts as quickly and efficiently as possible thanks to the proprietary technology "Equidist";
• equipped with special holes for enhanced heat dissipation;
• equipped with a powerful steel core;
• serves for quite a long time;
• can only work in dry mode;
• has a 2.223 cm bore.

There is also a special brick cutting disc model SPX-SL. The manufacturer claims that this device is designed for maximum performance. It is able to cope with lime-sand bricks, without creating an excessively high load on the engine. The segment is 1 cm high and 0.25 cm wide.

For normal operation, it is often necessary to buy brushes for the furrower's motor. They are absolutely necessary, but quickly clog up and need to be replaced frequently. In addition to these products, you also need to purchase:

• protective shields;
• dust accumulators;
• special hoses;
• cable cutters;
• tool kits;
• percussion-lever tool, which is used in conjunction with chasing chasers.

Replace discs only after turning off and de-energizing the tool. Only in this case is the complete safety of such a procedure guaranteed. Of course, before starting the gating, you should familiarize yourself with the communication diagram (pipes, wiring) and turn them off for a while in order to avoid problems. Remember that the furrower is loud. And without protective earplugs, it is undesirable to use it even for the shortest time.

You can increase the accuracy of the chasing with the help of the lower bounding bar. When assessing the required depth and width of the groove, one should pay attention not only to the parameters of the pipes or wires themselves, but also to the features of their termination. If you ignore this, then you usually have to redo the work or face additional difficulties. The wall chaser should be firmly held by both the primary and secondary strips. Transportation of the tool is possible only in special packaging provided by the manufacturer.
