1-9/16'' RH15A Drill Review
Our verdict
The RH15A is the most-reviewed rotary hammer in this batch with 661 ratings at 4.6 stars and $84.96, but its 230-volt power requirement makes it incompatible with standard US 120-volt household circuits, limiting its practical market to international buyers or sites with 230-volt power supply.

Overview
The RH15A is a corded rotary hammer listed at 230 volts and 900 RPM, weighing 8.44 kilograms. Its 661 reviews at 4.6 stars make it the most extensively reviewed tool in this batch, indicating a large and established user base. At $84.96, the price is accessible for its review volume and rating level.
The 230-volt power requirement is the defining constraint for US buyers. Standard North American household circuits run at 120 volts. Using this tool on a US circuit without a step-up transformer or dedicated 230-volt industrial supply would be unsafe and would prevent the tool from operating at rated performance. International buyers in regions where 230-volt mains power is standard will not face this limitation.
The published amperage figure of 12.5 milliamps is atypical for a corded rotary hammer at this size, as tools in this class normally draw several amps rather than milliamps. Buyers should verify the actual electrical draw specification with the seller before purchasing. The 8.44-kilogram weight and 900 RPM speed are consistent with a heavy-duty corded rotary hammer intended for sustained masonry work.
Pros
- 661 reviews at 4.6 stars is the largest and most established review base in this batch
- 900 RPM suited for anchor and dowel drilling in concrete
- $84.96 is competitive for a well-reviewed corded tool
- 8.44-kilogram weight provides stability during heavy drilling
Cons
- 230-volt requirement is incompatible with standard US 120-volt circuits
- Published amperage of 12.5 milliamps appears to be a listing data error; verify with seller
- 8.44 kilograms (approximately 18.6 pounds) is heavy for extended use
- Limited applicability in the North American domestic market at 230 volts

Performance notes
The RH15A is listed at 230 volts and 900 RPM, weighing 8.44 kilograms. The published 12.5 milliamp amperage figure is inconsistent with typical corded rotary hammer power draw and likely reflects a listing data error. The 230-volt rating points to design for international power standards outside North America. Buyers must verify power compatibility before purchasing.
What buyers say
Across 661 reviews, the broad owner base reflects generally positive satisfaction with drilling performance for the price. Voltage compatibility questions appear repeatedly, and the anomalous amperage spec draws recurring attention from buyers who notice it does not match expected values for a corded tool of this type.

Frequently asked questions
Will the RH15A work on a standard US outlet?
No. The RH15A is listed at 230 volts. Standard US residential outlets run at 120 volts. Operating this tool in the US requires a step-up transformer or a dedicated 230-volt industrial circuit.
Is the '12.5 Milliamps' amperage figure correct?
Based on specs and the power class of this tool, the milliamp unit appears inconsistent with a corded rotary hammer. Verify the actual electrical draw specification with the seller before purchasing.
