| Hitachi introduces lightest and most compact rotary hammer  Hitachi Power Tools announced its most compact and lightweight SDS hammer ever, the DH22PG. It is perfect for both overhead and extended use applications and also allows the user access to the tightest work areas. The DH22PG 7/8" SDS Plus Rotary Hammer is ideal for drilling small-diameter anchor holes in concrete and can also drill through wood and metal, as well as fasten with a chuck adaptor. This new offering from Hitachi is engineered with advanced features and is equipped for the professional who demands speed and reliability from a rotary hammer. The powerful 5.4 amp, 620 watt motor produces rapid results, especially in standard 5/32" and 3/16" diameter holes. (This rotary hammer can take on up to 24 inches per minute in medium density concrete with a 3/16" bit.) With low 8.75m/s2 full-load tri-axial vibration and a high full-load impact rate of up to 6,200 BPM, the DH22PG delivers a comfortable and impressive performance. In heavy-duty applications, comfort and convenience are of utmost importance and the DH22PG is designed with the user in mind. At just 4.2 Ibs and 11.4" in length, this rotary hammer is Hitachi's most compact and lightweight SDS rotary hammer yet. An adjustable 360° side handle provides secure control with a soft elastomer coating to helps absorb vibration. It can be removed when working in tight spaces for maximum maneuverability and also includes a ruled depth gauge to insure precise depth control. The DH22PG's tool-less chuck is sturdy and reliable and accepts SDS Plus bits with a simple "click." A retainer slides back to release the bit for quick and easy accessory changes. The mode selector dial makes the conversion from rotary hammer to drill-only simple and efficient. When using the hammer drill over an extended time, the lock-on speed button relieves the trigger during continuous operation with reduced user fatigue. A conveniently-placed reverse button allows backward rotation to quickly dislodge bound bits when necessary. Sealed to prevent grease leakage and protect the motor from dust and debris, the DH22PG delivers prolonged tool life and unmatched durability. An idle strike restrictor prohibits hammering while the tool is in no-load operation. This feature protects against unnecessary wear on internal tool components and reduces the no-load tri-axial vibration to 1.42 m/s2. The slip clutch prevents damaging reactions to excessive torque while the internal pressure adjustment minimizes pressure fluxuations that lead to inconsistent bit strike force. With this innovative feature, every strike hits its hardest- every time- for stable hammering and efficiently powerful drilling. write your comments about the article :: © 2008 Construction News :: home page |
