Question 1

What applications is the 1-3/4 in. SDS MAX Combination Rotary Hammer designed for?

Accepted Answer

This corded SDS MAX combination rotary hammer is designed for demanding concrete and masonry applications, including anchor and through-hole drilling, medium-duty demolition, and chipping. It is also suitable for dry coring with core bits up to 4 inches in diameter, high-performance horizontal serial drilling for #5–#8 rebar, and bushing applications.

Question 2

How much impact energy does this SDS MAX rotary hammer deliver?

Accepted Answer

The rotary hammer delivers up to 10.5 Joules of EPTA-rated impact energy, providing strong performance for drilling and chipping in hard concrete and masonry. Its constant-speed electronics help maintain operating speed under load, while the 14-amp motor supports demanding applications. The tool's midweight design makes it suitable for sustained horizontal drilling and chipping tasks.

Question 3

How does the E-CLUTCH system protect users during bind-up situations?

Accepted Answer

The E-CLUTCH system is designed to stop the rotation of the bit if the tool encounters a bind-up situation. This helps reduce the risk associated with unexpected bit lock-up during drilling. The system provides an added level of control when performing demanding concrete and masonry work, particularly when drilling larger holes or working with challenging materials.

Question 4

How does SHOCKS Active Vibration Control improve comfort during use?

Accepted Answer

The SHOCKS Active Vibration Control system is designed to reduce vibration felt by the user at the handles compared with rotary hammers without this feature. This can improve comfort during extended drilling, chipping, and demolition work. The vibration-reduction system is especially useful for professionals performing repetitive concrete and masonry applications with a heavy-duty SDS MAX tool.

Question 5

What drilling sizes and core bit capacities can this rotary hammer handle?

Accepted Answer

For anchor and through-hole drilling in concrete and masonry, the recommended hole diameter range is 5/8 inch to 1-1/4 inches. The rotary hammer can also perform dry coring in concrete and masonry using core bits up to 4 inches in diameter. Its 7-position variable-speed control provides additional adjustment for precision drilling and chipping applications.
