Hilti recently introduced a new lightweight automatic fastening tool that facilitates overhead applications.

In developing the new DX 351, weighing only 2.2 kg, Hilti has come up with the perfect sequel to a worldwide success story, says Mutaz Al Maani, market segment Manager at the Hilti regional office for the Middle East and South Asia. “Incorporating all the advantages of its highly esteemed forerunner, this handy tool offers a host of additional new features,” he says.
“Both the mechanical and electrical trades have a high percentage of overhead applications and the light weight and small dimensions of the DX 351 together with the already available pole tool will provide a very suitable solution for these customer groups.
“Designed and developed for interior finishing applications as well, the new DX 351 fastens systems on both concrete and steel at high speed and with minimum effort, and has proven its capabilities, especially when working overhead, and in repetitive fastening applications.
“Its secret lies in a unique combination of innovative specially-designed nails and the use of propellant cartridges of a lower power level. These enhancements have made a considerable reduction in recoil and noise, resulting in greater fastening comfort and significant improvement in efficiency.”
In an effort to reduce the energy required to drive a nail, the engineers at Hilti have optimised the nails thereby ensuring the same high fastening quality even with a shank of reduced diameter. DX 351 can also be used as a magazine tool, whereby collated nails can be used in serial applications such as using metal straps to fasten conduits or air ducts.
“These new nails permit the use of special white cartridges that provide the lower driving energy required to attain reliable fastenings of the highest quality,” says Al Maani. “The advantages to the user become immediately obvious: perfect fastenings with significantly less effort. It offers less stress and fatigue when working and results in greater progress and an increase in cost efficiency.
“Its simple working principle and innovative nail magazine makes it an easy-to-operate, fully-automatic fastening tool.
“Using the fastening tool, installation work in interior finishing can be speeded up considerably because of the handy strips of 10 nails in lengths of up to 27 mm. In addition, the quickly reloaded magazine, can drive in nails at a rate of up to 720 per hour – with minimum effort as the DX 351 is the lightest tool in its class.”
