Between harsh vibration and the occasional binding, big drills can cause big harm to your hands and wrists. Dewalt is reducing these risks with its Flexvolt 60V Max 2-inch Combination Hammer (DCH773), which mitigates vibration and ergonomic harm to the user with active vibration control and an E-clutch system. The E-clutch stops rotation anytime the tool stalls or binds and shuts it down if necessary.
For fast and efficient drilling the combination hammer puts out 19.4 joules of energy and 290 rpm using a 60-volt/12 amp-hour battery and brushless motor. Seven speed selections for drilling and chipping help tailor the force of the machine to the material at hand.
If you are looking for something lighter, the 20V Max 1-1/8 inch SDS Plus D-handle rotary hammer (DCH263) pounds out 3 Joules of energy at 1,165 rpm. This corded model has constant speed control, regardless of material density and also features active vibration control. It also features a brushless motor and includes a work light for improved drilling area illumination.
To meet the new dust mitigation rules, the smaller hammer can be paired with an enhanced onboard dust extractor, the DWH205DH, which is OSHA Table 1 compliant. The DWH205DH features three nozzle heads for maximum dust collection. The nozzles are tuned for up to 1-in. diameter bits, all stop bits up to 1.5-inch shoulders and small diameter bits up to 1/2-inch.
An additional tool Dewalt is bringing to the battle to stop dust is its new Universal Dust Extractor (DWH161) and SDS Dust Extraction Tube Kit (DWH200D).
The Universal Dust Extractor is an OSHA Table 1-compliant vacuum that is battery powered and can be used with a number of concrete tools including rotary hammers and hammer drills; as well as drywall cutout tools, sanders, routers and jigsaws.
The device weighs just 4.39 pounds with the included 2.0 amp-hour battery. Multiple strap positions enable you to position the backpack in different configurations to fit the needs of different applications and wireless tool control can pair the extractor for remote activation.
The SDS+ Dust Extraction Tube Kit (DWH200D) has three interchangeable tubes for 10- and 6-inch SDS+ drill bits and chisels plus a tube that fits a wide range of stop bits. The 3-foot-long hose has a side handle and an integrated depth stop. With adaptor rings you can use the Tube Kit with a variety of Dewalt tools.
The Universal Dust Extractor will be available this summer and retail for $249. The SDS+ Dust Extractor Tube Kit sells for $70 and is available now.
