Cordless Rotary Hammers
Cordless rotary hammers are a type of power tool that is used to drill holes in concrete, masonry, and other hard materials. They are typically powered by a battery, which makes them more portable than corded models. Cordless rotary hammers are available in a variety of sizes and power levels, so you can choose the one that is best suited for your needs.
Benefits of Cordless Rotary Hammers
There are a number of benefits to using a cordless rotary hammer, including:
- Portability: Cordless rotary hammers are much more portable than corded models, making them ideal for use in tight spaces or on jobsites where there is no access to power.
- Power: Cordless rotary hammers are still very powerful, even though they are powered by batteries. They can easily handle most drilling tasks, including drilling through concrete and masonry.
- Convenience: Cordless rotary hammers are very convenient to use. You don't have to worry about tripping over cords or having to find an outlet.
Types of Cordless Rotary Hammers
There are a few different types of cordless rotary hammers available, each with its own set of features.
- Hammer drills: Hammer drills are the most basic type of cordless rotary hammer. They are designed for drilling holes in concrete, masonry, and other hard materials.
- SDS-Plus rotary hammers: SDS-Plus rotary hammers are more powerful than hammer drills and are designed for more demanding drilling tasks. They can handle larger holes and more difficult materials.
- SDS-Max rotary hammers: SDS-Max rotary hammers are the most powerful type of cordless rotary hammer. They are designed for the most demanding drilling tasks, such as drilling through thick concrete or masonry.
Choosing the Right Cordless Rotary Hammer
When choosing a cordless rotary hammer, there are a few factors you need to consider, including:
- Power: The power of the cordless rotary hammer is measured in amps. The higher the amps, the more powerful the hammer will be.
- Speed: The speed of the cordless rotary hammer is measured in revolutions per minute (RPM). The higher the RPM, the faster the hammer will drill.
- Torque: The torque of the cordless rotary hammer is measured in foot-pounds (ft-lbs). The higher the torque, the more powerful the hammer will be.
- Battery life: The battery life of the cordless rotary hammer is measured in minutes. The longer the battery life, the longer you will be able to use the hammer before you need to recharge it.
Once you have considered these factors, you can choose the cordless rotary hammer that is best suited for your needs.
Types of Cordless Rotary Hammer Bits
Cordless rotary hammers use a variety of different bits, including:
- Masonry bits: Masonry bits are designed for drilling holes in concrete, masonry, and other hard materials.
- Carbide bits: Carbide bits are more durable than masonry bits and are designed for drilling through more difficult materials, such as rebar and steel.
- Pilot bits: Pilot bits are used to create a pilot hole for the masonry or carbide bit.
- SDS-Plus bits: SDS-Plus bits are used with SDS-Plus rotary hammers.
- SDS-Max bits: SDS-Max bits are used with SDS-Max rotary hammers.
