The safety and productivity of tradesman on jobsites is crucial to a construction business—and choosing the right business partners can significantly impact both. The partner of choice for the Bartley Corporation’s power tools has long been Hilti. The company sights Hilti’s continuous innovation in safety, productivity as well as new and enhanced features and services, as playing a big part in that decision. For Bartley, a commercial concrete construction company serving the Maryland and Washington, D.C. metropolitan areas, business is consistent and expanding. So, when the time came to outfit new crews with tools, project manager Chris Bartley jumped on the opportunity to introduce his teams to Hilti’s newest combination hammer drill, the TE 70-ATC/AVR. 

“In our industry, there are so many products to choose from,” he says. “When you’re dealing with heavy-duty concrete drilling and demolition, we must consider how physically demanding the applications are on the tool and our employees. What we’ve learned is that Hilti products are safer, more powerful, and last longer. That’s why we’ve been a customer for more than 10 years.” 


Hilti, a leading manufacturer and provider of construction tools, technology, and services recently expanded its rotary and combination hammer tool portfolio with the next generation TE 70-ATC/AVR. Construction professionals are looking for solutions that will deliver power, performance, and productivity. Hilti says the new and improved tool will do just that, helping commercial contractors break and drill up to 40 percent faster in reinforced concrete and demolish more concrete than the competitors in its class. Bartley agrees, which is why the tool is currently being used on nearly 30 of its jobsites in the Mid-Atlantic area including government and commercial office buildings. 

“We’re really impressed with overall power and performance,” says Bartley. “This is our tool of choice for the most challenging applications we encounter whether it’s drilling, installing anchors, or breaking concrete. We also do a ton of underpinning work, which entails strengthening the foundation of an existing structure—it gets the job done.” 

The SDS-Max combination hammer drill comes with a detachable power cord that fits eight other Hilti tools. The detachable power cord feature makes for quick cord changes and reduces repair downtime caused by cut or frayed cords. “Usually, it’s just a matter of time before something happens and you have to replace a cord,” says Bartley. “With the TE 70-ATC/AVR, it’s a different experience. Instead of workers’ tools being down for days because they have to replace a cord, they have a backup cord with them, put it on and keep going.” 


Understanding the importance of worker safety on a construction jobsite, Hilti equipped the SDS-Max combination hammer drill with its exclusive Active Torque Control (ATC) technology, which stops the tool body from spinning uncontrollably if the drill bit jams. It also features Hilti’s Active Vibration Reduction (AVR), a technology that makes it less tiring to use. 

“We’ve used previous models of the TE 70 but, I think the most noticeable change in this new tool is the safety technology ATC and AVR,” says Bartley. “Obviously, we’re concerned about our workers because when you’re drilling into concrete with rebar, that can be hard on the body. This tool addresses those concerns and keeps us safer and more productive throughout the day.”


What attracted Bartley to the SDS-Max combination hammer drill was Hilti’s services, including Tool Fleet Management. “I have several conversations a week with my account manager and the timing just so happen to work out perfectly,” says Bartley. “Hilti had a new power tool release and I needed to supply my new crews with a fleet of tools. It was seamless to adopt and implement the tool. With Hilti Fleet and service support, we can focus on other work crucial to the business.” 

Bartley has been around for 50 years, with its mission being to provide quality service, customer satisfaction, and innovation—a commitment they believe directly aligns with
Hilti. “This is a partnership. Hilti isn’t just selling us tools,” Bartley says. 

The TE 70-ATC/AVR is backed by the industry’s best tool services, available on Hilti’s Tool Fleet Management program or with Hilti’s warranty promise—20 years of repair or replacement of defective parts;
2 years no cost repair including wear and tear; and a guaranteed one-day turn-around on repairs.
