Detailed Performance Review
Drilling Performance
The TE 6-A36 excels at its primary function: drilling holes in concrete and masonry. During testing, it consistently delivered clean, precise holes in reinforced concrete up to 20mm in diameter. The optimal performance range of 6-16mm is where this tool truly shines, providing the perfect balance of speed and precision. The hammer action is powerful yet controlled, allowing for efficient drilling without excessive user fatigue.
What sets the TE 6-A36 apart from many competitors is its ability to maintain consistent performance throughout extended use. Many cordless rotary hammers experience noticeable power drops as the battery depletes, but the Hilti maintains its hammering force remarkably well until the battery is nearly exhausted. This consistency is invaluable on jobsites where predictable performance is essential.
Battery Life and Power Management
The 36V battery platform provides impressive runtime for a cordless rotary hammer. In typical drilling applications, you can expect to drill approximately 60-70 holes (10mm x 80mm depth) in concrete on a single charge of the 5.2Ah battery. For lighter drilling in softer materials, this number increases significantly.
Hilti’s intelligent power management system helps extend battery life by optimizing power delivery based on the application. This means you’re not wasting battery capacity when drilling into softer materials, yet full power is available when you need it for tougher applications. The battery also features a useful charge indicator, allowing you to monitor remaining capacity at a glance.
Ergonomics and User Comfort
The D-grip design of the TE 6-A36 contributes significantly to user comfort during extended operation. The grip is well-contoured with a rubberized coating that provides excellent control even when wearing work gloves. At 4.0kg with battery installed, it’s not the lightest option available, but the weight is well-balanced, reducing strain during overhead work.
Models equipped with Active Vibration Reduction (AVR) technology offer a noticeable improvement in user comfort during prolonged use. The system effectively dampens vibrations before they reach the handle, reducing fatigue and potentially minimizing the risk of hand-arm vibration syndrome for professionals who use rotary hammers regularly.
Versatility and Operating Modes
With three distinct operating modes – drilling, hammer drilling, and chiseling – the TE 6-A36 offers impressive versatility for a mid-sized rotary hammer. The mode selector is positioned for easy access and provides definitive clicks when changing between settings.
The drilling mode works well for wood and metal applications when paired with an appropriate chuck adapter. Hammer drilling mode delivers the full percussion force for concrete and masonry work. The chiseling mode, while not as powerful as dedicated demolition hammers, is more than adequate for light chipping, channel cutting, and tile removal tasks.
Dust Management System
The optional Dust Removal System (DRS) attachment is a standout feature for health-conscious users. When attached, it effectively captures up to 95% of dust at the source, significantly improving workplace air quality and reducing cleanup time. The system works through a vacuum effect, collecting dust in a transparent container that’s easy to empty.
While the DRS attachment does add some bulk and weight to the tool, the health benefits and time savings from reduced cleanup make it a worthwhile addition for regular users, particularly those working in enclosed spaces or on projects with strict dust control requirements.
Comparison with Alternatives
| Feature | Hilti TE 6-A36 | DeWalt DCH333 | Milwaukee M18 FUEL |
|---|---|---|---|
| Battery Platform | 36V | 54V FlexVolt | 18V |
| Impact Energy | 2.5 Joules | 3.5 Joules | 2.1 Joules |
| Weight (with battery) | 4.0 kg | 4.3 kg | 3.7 kg |
| Max Drilling Diameter | 20 mm | 26 mm | 28 mm |
| Vibration Control | AVR (select models) | Yes | Yes |
| Dust Extraction | Optional DRS | Optional attachment | Optional attachment |

| Warranty | 20 years limited | 3 years limited | 5 years limited |
While the Hilti TE 6-A36 commands a premium price compared to competitors, it justifies this with Hilti’s legendary durability and industry-leading warranty. The DeWalt offers more raw power for heavier applications, while the Milwaukee provides a lighter option that still delivers respectable performance. The Hilti strikes an excellent balance between power, weight, and reliability that makes it particularly well-suited for professionals who use their tools daily.

Real-World Applications
The Hilti TE 6-A36 particularly excels in these common applications:
Anchor Installation
The precise hammer drilling action makes this tool ideal for installing anchors in concrete. The consistent hole diameter and depth contribute to proper anchor seating and holding strength. The dust removal system further enhances this application by keeping holes clean for better anchor performance.
Electrical and Plumbing Installations
For trades requiring multiple penetrations through concrete walls and floors, the cordless freedom combined with reliable performance makes the TE 6-A36 a productivity enhancer. The ability to work without managing power cords is particularly valuable when moving frequently between installation points.
Renovation Work
The chiseling function, though not as powerful as dedicated demolition hammers, is more than adequate for removing tiles, creating channels for wiring, or minor concrete removal tasks. This versatility reduces the need to switch between multiple tools for different aspects of renovation work.
Rebar Detection
When paired with Hilti’s rebar detection technology, the TE 6-A36 becomes part of a system that helps avoid drilling into reinforcement bars, saving time, reducing bit damage, and enhancing safety.
Verdict
The Hilti TE 6-A36 represents a significant investment compared to other cordless rotary hammers, but delivers exceptional performance and durability that justifies its premium positioning. It strikes an excellent balance between power and portability, with the 36V battery platform providing ample power for demanding applications without the limitations of a power cord.
What truly sets this tool apart is its consistency and reliability. The TE 6-A36 delivers predictable performance throughout the battery cycle and maintains that performance over years of use. This reliability, combined with Hilti’s renowned service and warranty support, makes it a compelling choice for professionals who depend on their tools daily.
While hobbyists and occasional users might find better value in less expensive alternatives, professionals who factor in productivity, downtime, and total lifetime cost will appreciate the value proposition of the TE 6-A36. It’s not just a tool purchase; it’s an investment in productivity and reliability.
