hammer drill
B2Technical / DIY / Construction / Everyday (in relevant contexts)
Definition
Meaning
A power tool that both rotates and hammers (provides a percussive force) to drill into hard materials like masonry, concrete, or stone.
1. The tool itself. 2. The act of using such a tool (e.g., 'I need to hammer drill these holes'). 3. Sometimes used as a modifier for actions or accessories related to the tool.
Linguistics
Semantic Notes
It is a hyponym (specific type) of 'drill'. The key semantic component is the combined rotary and percussive action, distinguishing it from a standard 'drill' (rotary only) or an 'impact driver' (rotary with a tangential impact for driving screws).
Dialectal Variation
British vs American Usage
Differences
Minimal. The term is identical. Spelling follows regional norms (e.g., 'hammer drill' vs. 'hammer drill'). 'SDS drill' (a proprietary brand name for a common type of hammer drill mechanism) is more commonly used in the UK as a near-synonym.
Connotations
Both regions associate it strongly with construction and serious DIY. In the UK, 'drill' alone might be assumed to be a standard rotary drill, while 'hammer drill' specifies the masonry function.
Frequency
Equally frequent in technical/DIY contexts in both regions.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'молоток' (hammer) + 'дрель' (drill) as separate words in description; the standard term is 'перфоратор' (perforator). 'Ударная дрель' is a less common but accurate translation.
- Confusing 'hammer drill' (перфоратор) with 'impact driver' (импактный шуруповёрт), which is for screws, not drilling masonry.
Common Mistakes
- Using 'hammer drill' to refer to any powerful drill. (e.g., a large corded drill for metal is not a hammer drill unless it has a percussion function).
- Using it as a verb without context (e.g., 'I hammered' is ambiguous; 'I hammer-drilled' is clearer).

FAQ
Frequently Asked Questions
Yes, most hammer drills have a switch to turn off the hammer function, allowing them to be used as a standard rotary drill for wood or metal.
A hammer drill delivers a direct, linear hammering force to help drill into hard materials. An impact driver delivers a rotational 'hammering' force (torque) to drive screws and loosen stuck fasteners. They are designed for different tasks.
Yes, you must use masonry bits (often with a carbide tip) designed to withstand the percussive force. Using standard wood or metal bits in hammer mode will destroy them.
They are similar, but a rotary hammer is typically a larger, more powerful professional tool that uses a different mechanism (often an SDS-plus or SDS-max chuck). In everyday language, the terms are often used interchangeably, though 'rotary hammer' usually refers to heavier-duty models.
