With each passing year, power tools pack more of a punch, become lighter in weight and are safer to use – all great news for you, the end-user, on the jobsite. To give you an idea of the many types of tools and endless advances in features available to you and your crew, Masonry has created a power tool round-up showcasing the endless array of bells and whistles. This review will allow you a snapshot of what a few of our industry’s top manufacturers are offering in the way of power tools.

Bosch Rotary Hammers Bosch Power Tools andBosch Rotary Hammers Bosch Power Tools and Accessories Farmington Hills, Mich. Bosch Power Tools and Accessories introduces three new, super powerful rotary hammers that maximize impact energy, minimize vibration levels, yet maintain manageable size and weight to provide the utmost comfort in extended chiseling and drilling. Bosch has incorporated its patented Active Vibration Control technology into the newest members of the Bulldog family, 1-1/8-inch SDS-Plus RH328VC, RH328VCQ and 1-1/4-inch SDS-plus RH432VCQ Rotary Hammers. This technology reduces vibration in both the hammer mechanism and the grip area to reduce overall vibration by as much as 50 percent. The RH432VCQ operates at 8.5 amps with 3.7-foot-pounds of impact energy, making it the fastest drilling SDS-plus hammer in its class. www.boschtools.com EDCO Core DrillsEDCO Core Drills EDCO - Equipment Development Company Frederick, Md.

The Hilti CPC battery technology protects the battery, switch and motor for increased durability and longer battery life. This cordless rotary hammer comes standard with a high-efficiency motor for longer tool life and productivity, as well as a drop-resistant housing to achieve maximum protection of the tool’s vital components. It also is built with a keyless “click” chuck for fast and easy drill bit changes. www.hilti.com Husqvarna Power CutterHusqvarna Power Cutter Husqvarna Construction Products Olathe, Kan. Husqvarna’s K1260 power cutter follows in the footsteps of the K760 and K970 power cutters. Its 7.8-hp engine produces more output, and the built-in automatic filter compensation unit, SmartCarb, helps maintain high power and lowers fuel consumption. The Active Air Filtration system is one of the market’s most efficient air filtration systems. It delivers operational times (dry cutting) of about one year without filter service required. The Poly V-belt provides better power transmission, less retensioning and increased product life. The DEX, dust-handling system, provides cleaner cutting with less water usage. www.husqvarna.com Metabo Lightweight Angle GrinderMetabo Lightweight Angle Grinder Metabo Corp. West Chester, Pa. Metabo Corp.’s WP780 4.5-inch angle grinder has a non-locking paddle switch and a “Deadman” function that increases user safety by turning the grinder off automatically when its trigger is released or the tool is dropped. Built to withstand rugged operating conditions, including edge grinding, deburring, weld grinding, metal removal and tile cutting, the WP780 features a robust, 7.2-A motor with 780 watts of power, 14 inch-pounds of torque and a no-load speed of 11,000 rpm.

Many models also include Constant Power Technology, enabling the grinder to maintain speed under load. An airflow system allows air to move rapidly through the tool, keeping the motor cool and delivering optimal performance. L-shaped vents protect the motor by blocking debris particles. www.milwaukeetool.com Multiquip Four-Cycle RammerMultiquip Four-Cycle Rammer Multiquip Carson, Calif. Multiquip’s Four-Cycle Rammer is designed for high efficiency with lower exhaust emissions, less noise and better fuel economy than standard two-cycle rammers. There is no need for mixed fuel. The engine is lubricated through the crankcase instead of through the fuel, so no oil is burned in the cylinder, reducing carbon buildup and minimizing gumming problems. The Rammer has a long-lasting composite clutch; a built-in hourmeter/tachometer; throttle control; and a cyclonic air filtration system. The MTR40F has an ability to work in confined spaces and is lightweight and portable – only 101 pounds. Grease lubrication minimizes the body size. A four-stage air filtration traps more than 99 percent of engine-damaging airborne dirt and dust particles. www.multiquip.com STIHL Electronic Water Control on Cut-OffsSTIHL Electronic Water Control on Cut-Offs STIHL Virginia Beach, Va.

When using this feature, the flow of water stops at idle speed and starts again automatically when the throttle is engaged. Key features include the X2 Air Filtration System; an anti-vibration system; an upright, large-capacity fuel tank; a top-handle, lightweight and compact design; and increased fuel efficiency and reduced emissions. www.stihlusa.com
