Hammer Drill vs. Impact Drill

bosch-corded-hammer-drillAnother electric drill design innovation is the hammer drill. It is a tool that drills like a drill bit while also providing an impact action.

Like all other major brands, the Bosch hammer drill is a fantastic piece of equipment. You will receive a tremendous tool that easily drills 5/8″ holes in concrete when you purchase this kit.

The electric rotary hammers for concrete provide hard-hitting performance and increased productivity while reducing vibration.

If you’re going to be doing concrete all day, I’d recommend getting a more extensive drill. That said, this is a professional-grade tool that will quickly fulfill the majority of your needs. In addition, it has a high amperage, making it an excellent hammer for a variety of tasks.

It gets a little warm at the hammerhead end, but it cools down quickly if you let it rest between concrete breaking sessions.

Have you ever tried drilling through fifty-year-old concrete with a standard tool? Unfortunately, if you attempt this task with a standard drill, you will have many problems with the hammer function.

Unlike those other low-cost hammer drills, the Bosch drill will get the job done quickly. You’ll be well on your way to a good job closeout if you use the SDS on this tool with various bits.

Tool-free bit changes, automated bit locking, dust prevention, and maximum impact energy transmission are all features of the SDS-plus bit system.

Bosch Bulldog Xtreme Rotary Hammer Drills Specification

The Bosch hammer drill is recognized for its toughness, and this model is no exception! It accomplishes exactly what it was designed to. The hammer drill has a multi-function selector that quickly switches between rotation-only, rotary hammer, and hammer-only modes for maximum versatility. It also includes a variable-speed reversing trigger for precise bit starts and easy fastener and bound bit removal.

The D-handle shape of the rotary hammer is suited for above and downward drilling tasks. A variable-speed trigger with reverse allows for precise bit initiation and removal of fasteners or bound bits. If the bit gets stuck, an integrated clutch disengages torque transmission. A patented rotating brush plate gives you the same amount of power and flexibility.

Rotary hammers use field-core interlocking steel laminations, a dual ball bearing armature, and additional copper commutator bars to maximize energy transfer efficiency and tool life. To complete the most complex operations, the constant speed control automatically applies more power to the motor to maintain speed under load.

Demolition crews, general contractors, building sites, residential development, and commercial construction benefit from Bosch drills. Hammer drills are most often used in concrete and masonry drilling.

Hammer Drill User Tips

The hammering action of a hammer drill provides extra power because the hammer drill’s force is applied directly to the bit. However, the hammering component of this motion can be disabled, allowing the tool to operate more like a traditional drill.

A cam-action or percussion hammering mechanism is used in hammer drills, in which two sets of toothed gears mechanically interact with one another to hammer while the drill bit rotates. Routine drilling, hammer drilling, and hammer chiseling are all possible with these unique techniques.

You can select the mode you want to use by hand-turning a collar between the chuck and the forward end of the housing. For example, a hammer drill features a particular clutch that punches the drill bit in and out along its axis and spins it.

The bit’s actual travel distance and blow force are minimal, and the hammering operation is extremely fast, expressed in thousands of blows per minute (BPM). This motion can be employed alone or in addition to a standard rotating motion. For example, a standard drill is a valuable tool, but you can do more with the hammer mode incorporated.

Other Hammer Drilling Techniques

You may use the hammer mode with a gouge chisel to execute work like hollowing, carving in the round, or bas-relief considerably faster and with less effort than you can with the chisel and mallet technique. This is because the chuck on cam-action drills features a mechanism that allows the entire chuck and bit to move forward and backward on the rotation axis.

Anchor bolts, masonry screws, and wall fasteners all require holes in hard materials. Hammer drills are often used to drill holes in concrete, masonry, or stone rather than industrial construction drilling.


You can use this type of drill with or without the hammer action, but you can not use the hammer action alone because the rotation of the cams causes the hammer motion.

When making holes in concrete or masonry, the practical side combines the hammer and rotational operations. For example, install a butt chisel and use the hammer mode to build hinge mortises, clean out housing, or create tenon cavities.

Despite the subtle energy of each hit, the thousands of blows per minute are more than enough to break up concrete or brick, with the carbide wedge of the masonry drill bit crushing it for the spiral flutes to sweep away.

Hammer Drill vs. Impact Drill

With the impact mode turned on, you may drill three to five times quicker. As a result, a hammer drill drills through concrete or brick significantly faster than a standard drill. The hammer drill’s combination of size, capacity, and speed make it suitable for doing concrete drilling, masonry drilling, etc.

The fundamental difference is in the force applied to the drill head. The more powerful a hammer drill is, the larger the holes it can make and the faster it can travel through concrete. In contrast to an impact drill, which delivers an impact, a hammer drill has a hammer action.

Cordless technology is increasingly being used to power hammer drills. The type of drill you select is determined by the kind of work you do. It would help if you also inquired about any special features you desire for your hammer drill. Manufacturers who have been in business for a long time are likely to be around still when you need a replacement part for your power tool.
