This week we look at a SDS rotary hammer from DeWalt and a metal circular saw from Bosch. Click to begin the slide show.
Product Snapshot: Rotary Hammer and Metal Circular Saw
The GKM LI Professional Cordless Metal Circular Saw weighs under 6 lb and runs on Bosch�s 4-amp-hour, 18V lithium-ion battery platform. The saw makes a non-abrasive cut in metal, unlike a rip saw or an angle grinder. Fewer sparks are generated as a result, and the operator has a clearer view of the cutting surface. Cuts made with the saw also require less rework than an angle grinder or rip saw, with less discoloration or burr formation on the metal. The circular saw can be used for cutting pipe, threaded rod, corrugated sheet metal as well as for finish work during steel erection.

The Vermeer PTX40 Service Plow With Trencher is designed for utility installations that may need to get into difficult-to-reach places. Controlled by a wired remote-control unit, the PTX40 has a minimum working width of 40.2 in. and is only 7 ft long, allowing it to get into spaces in which many ride-behind trenchers can�t access. The plow has a maximum work- ing depth of 24 in., and the trencher can cut to a maximum depth of 42 in. The machine�s creep speed is electronically controlled for smoother performance during plowing and trenching operations. Also available is an optional bore attachment, which can deliver a maximum torque of 620 ft-lb.

DeWalt�s updated line of SDS Rotary Hammers includes four models that boast improved drilling speeds and vibration control. Internal and external rubber seals prevent dust and debris from damaging the motor. According to the manufacturer, vibration felt by the user has been reduced compared to earlier models. A rotating brush ring on the hammer allows for full power to be applied in reverse mode if the tool should jam. The DeWalt SDS Hammer line includes 11?2-in., 1-in. and 7?8-in. models, as well as a 1-in. hammer with a pistol grip.

The WA30-80 Wheel Loader is powered by a 6.69-liter, 191-hp engine that meets Tier 4 Final emissions standards. The Komatsu SAA6D107E-3 turbocharged engine features improved fuel economy, using up to 6% less fuel than the Tier 4 Interim engine in the previous wheel-loader model. The emissions system uses a diesel-particulate filter and diesel-exhaust fluid that must be serviced at regular intervals. An electronically controlled lockup torque converter provides optimized torque, resulting in better acceleration performance, higher top speed and improved hill climbing. The cab features an air-suspension operator�s seat and a 7-in. color rear-view backup camera.
