A hammer drill with a hammer-only mode is a specialized power tool designed for tasks that require intense hammering without any rotational motion. This versatile tool is a must-have for DIY enthusiasts, contractors, and professionals who frequently work with concrete, brick, or masonry. In this comprehensive guide, we’ll delve into the technical specifications, key features, and practical applications of this powerful tool.
Technical Specifications
Hammer-Only Mode
The defining feature of a hammer drill with a hammer-only mode is its ability to operate without any rotation, providing a pure, focused hammering action. This mode is particularly useful when using chisel bits, as it prevents the bit from spinning and allows for more controlled and precise chiseling, breaking, or demolishing tasks.
Impact Energy
The impact energy of a hammer drill is measured in foot-pounds (ft-lbs) or joules (J) and indicates the drill’s ability to deliver forceful blows. Higher impact energy generally translates to more powerful and efficient hammering, making it better suited for more demanding tasks. Typical impact energy ranges from 1.2 ft-lbs (1.6 J) for lighter-duty models to 12 ft-lbs (16.3 J) or more for heavy-duty options.
Motor Power
The motor power of a hammer drill is typically measured in amps (A) and reflects the drill’s overall efficiency and performance. A higher motor power generally means the drill can handle more demanding tasks with greater ease and speed. Corded hammer drills with hammer-only mode typically range from 6 to 12 amps, while cordless models can vary from 18V to 60V.
Chuck Type
Hammer drills and rotary hammers often utilize SDS (Slotted Drive System) chucks, which provide a more secure and stable grip for the chisel bits or other accessories used in hammering applications. SDS chucks come in various sizes, such as SDS-Plus and SDS-Max, with the latter being suitable for larger, more powerful tools.
Price Range
Hammer drills with a hammer-only mode can vary significantly in price, ranging from around $119 for entry-level models to $1,536 or more for professional-grade, heavy-duty options. The price is typically influenced by factors such as brand, power, features, and overall quality.
Key Features
Hammer Action
The hammer action of a drill refers to its ability to deliver a pounding force, often measured in beats per minute (BPM). Higher BPM generally translates to more efficient and effective hammering, making the tool better suited for tasks that require intense chiseling or breaking.
Drill Mode
Many hammer drills with a hammer-only mode also feature a standard drill mode, allowing the tool to be used for regular drilling tasks, such as drilling holes in wood, metal, or plastic. This versatility makes the hammer drill a valuable addition to any DIY or professional toolbox.
Chuck Size
The size of the chuck on a hammer drill determines the maximum recommended hole size the tool can handle. Typical chuck sizes range from 1/2 inch to 1 inch, with larger chucks being more suitable for heavier-duty applications.
Comparison to Rotary Hammers
Rotary hammers are a more powerful and specialized type of tool compared to hammer drills with a hammer-only mode. Rotary hammers are designed specifically for heavy-duty masonry work, such as breaking up concrete or removing mortar. They typically have a more powerful hammering mechanism and a dedicated hammer-only mode, making them better suited for the most demanding masonry tasks.
