12- and 14-In. Premium Segmented Rim Diamond Blades
Bosch 12- and 14-in. Premium Segmented Rim Diamond Blades deliver fast, efficient cutting in concrete and other hard materials, thanks to a tensioned blade core and a high-quality diamond formulation. The tensioned steel core is engineered to ensure that each blade delivers smooth cuts with low vibration to reduce blade wobble.
These general-purpose, segmented rim blades offer a diamond formulation that cuts most masonry and concrete materials. The 10-mm segment height provides up to 3X life versus standard diamond blades.
Each segment is laser welded to the steel core, offering the blade high mechanical strength and rigidity and ensuring greater stability during the cut.
Bosch 12- and 14-in. Premium Segmented Rim Diamond Blade reduction rings are 1 in. to 20 mm, which allows the blade to be used on application-specific concrete-cutting saws. The drive pin ensures the blade can be used on a walk-behind saw. These blades provide long life and smooth, fast cuts in concrete and masonry.
The Bosch DDS183 drill/driver and HDS183 hammer drill/driver feature Bosch KickBack Control, an integrated acceleration sensor that virtually stops the drill’s rotation during bit bind-up situations. The Bosch drill/driver also boasts an efficient EC brushless motor that provides longer tool life, great tool runtime and no maintenance. The Compact Tough design ensures a short head length and light weight. A built-in LED offers improved visibility in dark work areas.
The drill/driver and hammer drill/driver are engineered with an upgraded, heavy-duty, all-metal chuck that offers increased robustness and great gripping power for better torque transfer. The single-sleeve, keyless, 1/2-in. auto-lock chuck delivers quick bit changes.
Both tools deliver 531 in.-lbs. of torque and two drilling speeds (0–1,900 rpm high speed; 0–600 rpm for torque). In addition, the drill/driver offers 20+1 clutch settings to reduce fastener damage and cam out. A motor brake on the tool provides an immediate stop for fast repetitive driving jobs. In addition, the hammer drill features 28,500 bpm.
For high-power cutting and grinding of concrete and masonry, the DEWALT 60V MAX* 4.5- to 6-In. Grinder features a brushless motor that maximizes runtime for demanding applications, allowing for up to 126 cuts of -inch rebar on a single charge using a FLEXVOLT battery and 6-inch FLEXVOLT cutting wheel. The grinder is also a Perform & Protect tool, designed to provide a high level of tool control without sacrificing performance. Key features of the DEWALT 60V MAX* 4.5- to 6-In. Grinder include its Kickback Brake, which automatically shuts down and slows the wheel to a stop when a wheel pinch is detected. It has power equivalent to 13 amps or 1,700 MWO (as compared to the D28144) and a brake with less than 2-second stop time that slows the wheel when the trigger is released.
The grinder includes a two-stage trigger that reduces the chance for accidental start-up. Included with the grinder kit is a 4.5-in. Type 27 and a 6-in. Type 27 grinding guard. With the grinder’s One-Touch Guard Compatibility, the user has the option to utilize a one- or two-touch guard option with a simple lever adjustment.
Newport News, Va.
With the 881 Cut-off Saw series, Solo Inc. introduces the world’s first iLube engine. iLube, which stands for “intelligent lubrication,” eliminates the need for pre-mixed gasoline. It is a patented system for separate engine lubrication. From a separate oil tank with a volume capacity of 10.8 oz./0.32 liters, an electronically controlled pump adds the correct quantity of two-stroke oil, metered to suit the engine speed, to the fuel. There is no need to pre-mix fuel and oil. This eliminates any risk of incorrect fueling – a main cause of expensive engine damage. The full contents of the separate oil tank are sufficient for up to 20 fuel tank fillings.
Available in both 12 in./300 mm and 14 in./350 mm, the 881 models are powered by an 81-cc SOLO two-stroke high-performance engine. The utilization of the latest technology helps the environment by keeping emissions clean without significant loss of power. Thanks to an automatic choke system, which eliminates the need for a manual choke, the saw can be easily started on every use. The One-Push-Stop System allows the operator to safely stop the saw with the push of a button.
Specifically designed for use with handheld saws, Hilti Equidist diamond blades offer exceptional cutting speeds and long life, giving the user high productivity.
Engineered with the highest-quality industrial-grade diamonds available and quality-controlled bonded matrixes, the Equidist diamond blades provide superior cutting performance. The Equidist arranged diamond technology optimizes cutting in the most demanding applications. The SPX masonry blades are designed for cutting masonry materials (brick, block, stone, etc.), while the SPX universal blades excel in a variety of base materials, including cured concrete, reinforced concrete and concrete block.
In addition, the Equidist diamond blades outperform standard impregnated segments with up to 50 percent faster cutting speed, while offering the best life of any handheld blade on the market.
