CORE BUSINESS INDEED
Published: 4/3, 2020
For many professional contractors, diamond drilling is a core business in every sense of the word. Vertical drilling, horizontal drilling, overhead drilling, stitch drilling is what they do - day in and day out. To stay on top of their game, they need high-performing and reliable equipment. That’s where suppliers come to the rescue with their ‘latest and greatest’ solutions.
Husqvarna expands electric motor range
Sweden-based market leader Husqvarna has expanded its range of electric drill motors with the addition of two
single-phase 4.3-hp (3.2kW) models that combine the manufacturer’s trademark user-friendliness with increased sturdiness. Featuring a durable aluminium casing, the new DM 400 and DM 430 are designed for heavy-duty applications. Compact design makes the machines suitable for work in confined spaces and narrow corners. The carrying handle, which also functions as an impact guard, is easy to remove for extra clearance in tight areas. The machines boast such familiar Husqvarna features as a LED load indicator, the SmartStart (half-speed) button, and quick coupling to the new Husqvarna DS 500 stand. The three-speed gearbox makes it easy to adjust rpms to the core diameter—2.1 to 13.8 in (55 to 350mm) in for DM 400, and 3.9-17.7 in (100 to 450mm) for the DM 430.
The air-cooled heavy-duty electric motor is built to withstand high loads without overheating. The durable carbon brushes are easy to inspect and replace. To protect the motor and gearbox in case of the core bit jamming, the machines are equipped with two independent systems – a mechanical friction clutch and the Husqvarna Elgard™ electronic motor overload protection. Both models feature the Embedded Connectivity system, an enhanced version of Husqvarna Fleet Services. It harvests and analyses key performance indicators in the continuous mode.
Shibuya extends the ‘Blue-Drill’ series
Shibuya, a drilling and cutting machinery specialist based in Hiroshima, Japan, has added a new coring system to its Blue-Drill series, launched in 2019. The system, intended for up to 9.8 in (250mm) coring jobs, consists of the H2021 electric drill motor and the TS-255 rig. The redesigned motor has a rated output of 4.6 hp (3.4kW), representing a 95% increase in power on the forerunning R2021 model. Tripping has been minimized by adding a high-capacity circuit protector, and the gears have been modernized without increasing the machine’s overall weight. The system’s other highlights include a built-in on/off switch with motor overload protection, a multi-position swivel water inlet, and a portable residual current device (PRCD) that automatically shuts off electricity in the event of electric leakage. A water collection ring and a set of wrenches and Allen keys are included in the scope of supply. The AB52 swivel base is available as an option.
Tyrolit launches a new wet drill drilling system
The new core drilling system DRS250 from Tyrolit-Hydrostress combines the construction simplicity with a large diameter range. Designed for up to 9.8-in (250mm) wet drilling jobs, the system features a powerful 3.3-hp (2.5kW) drill motor and a two-speed oil-bath gearbox for efficient lubrication in every working position and optimal torque-to-speed ratio. The compact and lightweight construction guarantees easy handling and user-friendliness. A mechanical overload clutch and integrated PRCD safety switch allow for operational safety while an optional vacuum plate simplifies the machine setting-up.
An ingenious drilling solution from Fast Verdini
A family-owned company with a track record of over 65 years, Fast Verdini from Italy specialises in manufacturing compact and lightweight equipment for demolition, road-building and general construction applications. Its latest core drilling system, the CT 300, was said to be a showstopper at a construction exhibition in Toronto, attracting a lot of interest from the Canadian audience.
Equipped with a 3.2-hp (2.4kW) three-speed Weka drill motor, with a 3.75-hp (2.8kW) two-speed one as an alternative, the CT 300 boasts an innovative stand assembly that is 360° rotatable both vertically and horizontally. This allows drilling of walls, floors and ceilings from a single position on the floor. The drill motor features a differential circuit breaker incorporated in the power cable and a mechanical clutch to protect internal components. The drill feed is controlled via a hand wheel that can be fitted onto two different pins, which permits the operator to vary the feeding speed. The system is designed to operate with core bits ranging in diameter from 1.2 to 15.7 in (30 to 400mm).
Cuttronix is on a roll
Kaskod-Mtronix, an Estonia-based manufacturer of high frequency drilling and sawing machines that made a spectacular entrance at Bauma last year, keeps expanding its range with new machines. The manufacturer’s next generation Cuttronix CM-10 drill motors featuring the proprietary ISRCdrive™ technology is designed with high performance, reliability, safety and operator comfort in mind. The new drills can operate in one- or three-phase mode. In the three-phase mode, the motor continues to function even when one of the phases fails. The ISRCdrive™ technology with its advanced algorithms for motor control allows reducing the overall system cost while integrating motor, gearbox, and motor control system in one compact package. The 13.4-hp (10kW) rated output power, with a peak output of 20.1 hp (15kW) combines with the durable changeable spindle gearboxes to allow users to perform any drilling jobs in masonry and reinforced concrete in the .7 to 39 in (20 to 1,000mm) diameter range. The motors feature robust extruded aluminium housing with an IP66 ingress protection rating for use in harsh environments and wide range of working temperatures. Durable metal contactless buttons and switches are dirt- and dust-proof. Integrated safety elements, such as mechanical slip clutch for gearbox protection and overload protection, ensure safety and increase the motor’s lifetime. More innovative core drill models with built-in autofeed system and remote control functions are slated for launch in the first half of 2020.
AGP unveils a new heavy hitter
Taiwan-based manufacturer of power tools AGP has beefed its portfolio of drilling solutions with a 3.3-hp (2.5kW) three-speed drill motor designed for heavy-duty tasks. Featuring an aluminium housing, the new DM8P is a versatile machine suitable for up to 7.9 in (202mm) wet drilling in various materilas. The motor maintans constant speed even under heavy loads allowing for fast and efficient drilling. A built-in LED load indicator permits users to run the drill at optimal efficiency. The Taiwanese manufacturer recommends using the DM8P in combination with the AS200 or S350 drill stand.
True innovations from Milwaukee
Milwaukee has brought the professional core drilling industry into a new paradigm by launching the world’s first battery driven heavy duty core drilling system. The system is part of the new MX Fuel range which also contains battery driven power cutters, jack hammars, lighting towers, etc. A full reprt you will find on pages 36-40.
