DeWalt drives forward

The early part of 2010 has seen DeWalt introduce several innovative products. First to be launched in January was a range of accessories designed specifically for use with impact drivers. The 1/4in hex shank bits are engineered to cope with the high speed and torque generated in such applications, and the line-up consists of metal drill bits that can also drill plastic and wood, holesaws, flatwood bits, screwdriver bits, socket sets, and a 1/2in square drive to 1/4n hex shank adaptor, enabling attachment to an impact wrench. A new line-up of low-vibration SDS-plus hammers with dust

extraction systems includes integrated corded and cordless systems, as well as an adaptor for retro-fitment to any existing DeWalt SDS-plus hammer. The flagship product is the DC234KL 36V rotary hammer,

designed to produce low vibration and dust-free drilling in conjunction with the new D25302DH integrated dust extraction adaptor. The latter attaches to the bottom of the tool and draws its power from the drill’s 36V battery. Having an independent motor is said to ensure that full suction power is achieved without reducing drilling performance. The internal gearbox of the DC234KL itself has a suspended gear case, which helps the tool achieve a triaxial HAV rating of 8m/s2

, and

the Lithium-ion batteries used now come with a two-year warranty. The D25324K, in conjunction with the D25300DH adaptor, is the equivalent mains powered system, while the D25301 is available to fit existing hammer drills.

Bosch hammers it home

Bosch’s new rotary hammer, the GBH 3-28 DFR Professional Compact Multidrill, is claimed to offer 20% more power and a reduction in vibration by a similar amount compared to other hammers in the 3kg class. It is aimed at workers such as electricians and plumbers undertaking light-duty chiselling tasks like removing tiles, or drilling holes for anchors and fixings with diameters of 10-16mm. A quick-change chuck facilitates switching between drilling with impact in concrete, and drilling without impact in wood and metal. Also new in the manufacturer’s cordless SDS+ range is the GBH 18V-LI Professional rotary hammer.Weighing only 2.6kg and with an overall length of 285mm (the same size as an A4 sheet of paper), it offers 1.7J of impact energy and the Lithium- ion battery enables up to 115 6x40mm holes to be drilled in concrete before recharging is required. An electronic protection system shuts down the motor in an

overload situation, and a DuraShield housing is said to enable the machine to survive a 2m drop onto concrete. The tool can be used for drilling in concrete, stone and masonry, with the optimum drilling diameter being from 4-12mm. A cell protection system protects the battery against overheating and total discharge.

Marcrist’s tile solutions

Marcrist International has updated its PG850 professional tile drilling range. Improvements include an up-rated pumping mechanism on the 1-litre water bottle to create pressure more quickly, and stronger plastic is used. A new professional 3-litre bottle is also available. Also launched is an improved water swivel, made from higher quality steel for improved performance, and it incorporates a new ball valve and tap, replacing the current flow valve, for ease of use and avoidance of leaks. A new professional steel drill guide is designed to fit all sizes of tile drill

from 6-112mm and to offer enhanced accuracy whilst preventing wear. The existing plastic guide, which was suitable for 6-80mm drills only, will be retained as part of a new starter kit, which also comprises the improved water swivel and 1 litre bottle, the plastic guide and 2m of 8mm plastic tubing, along with a 6mm PG850 tile drill and a core extraction kit. A new water collection system and drilling guide can be used in tandem

with a wet vacuum for efficient drilling without water spillage, and completing the line-up are 7mm and 53mm tile drill sizes, specifically for bathroom tiling applications. A Professional Upgrade Kit is available, which includes the 3-litre bottle, core extraction kit and water swivel, along with the water collection system and drilling guide.
