Most electric hammer drills are rated (input power) at between 600 and 1100 watts. The efficiency is usually 50-60% i.e. 1000 watts of input is converted into 500-600 watts of output (rotation of the drill and hammering action).
How much power does my drill have?
Power. For cordless drills, power is measured in battery voltage. Higher voltage means more torque-spinning strength to overcome resistance. Over the last decade, top-end voltage has increased from 9.6 to 18V, but the range of models include 6, 7.2, 9.6, 12, 14.4 and 18V.
What is the input energy of an electric drill?
The electrical energy from the drill is transferred to the drill bit as kinetic energy. The drill bit turns and drills into the metal. But the drill also makes a lot of noise. Energy is used to make sound and the drill bits get hot, so some of the energy is converted into thermal energy.
Is a 500 watt drill powerful?
Power. With corded electric drills, power is normally quoted as wattage in the UK (horsepower in the USA), the higher the wattage, the more powerful. Most diy models are in the range 500 to 1000 W. … A low wattage drill used hard will be working at maximum power all the time working its bearings etc.
What tool is electric drill?
drill, cylindrical end-cutting tool used to originate or enlarge circular holes in solid material. Usually, drills are rotated by a drilling machine and fed into stationary work, but on other types of machines a stationary drill may be fed into rotating work or drill and work may rotate in opposite directions.
What makes a drill powerful?
Cordless drill power is measured in volts. The higher the voltage rating is, the more powerful the drill. Battery sizes typically range from 12V to 20V.
What is a good torque for a drill?
Newton Metres (Nm) on drills:
4 to 15Nm is fine for all of those smaller screw driver tasks around the home. 15 to 35Nm is a great all-rounder to drill and drive medium sizes screws and hole drilling. 35Nm upward will tackle all of those more serious project with bigger screws and holes.
Where does the electrical energy of a drill come from?
An electric drill converts electricity into mechanical energy (in the rotating drill bit) using an electric motor. As the drill bit bites into the material you’re drilling, the mechanical energy is converted into heat energy.
What is output energy?
‘Output energy’ is the amount of energy going out of a system.
What is the output of a hand drill?
The efficiency is usually 50-60% i.e. 1000 watts of input is converted into 500-600 watts of output (rotation of the drill and hammering action). The hammer action is provided by two cam plates that make the chuck rapidly pulse forward and backward as the drill spins on its axis.
What does wattage mean in power tools?
A watt is a unit of power. … A watt is equal to one joule (the basic unit of energy) per second. Any electrical device will draw a given number of watts, which will vary depending on the amount of power the device requires. A big electric saw will use more energy in a given period of time than a small hand-held drill.
How many speeds does a drill have?
Most drill/drivers have two speeds, but this one has three for an even finer adjustment. The adjustable gearing provides versatility based on the task you will be performing. Setting 1 is low speed/high torque and is best for driving screws. Setting 2 is a medium speed/torque and can be used for drilling or driving.
What materials are power drills made of?
Drill Bit Materials
- Carbon Tool Steels. Carbon tool steels are used for applications where little heat is going to be generated. …
- High-Speed Steel. …
- Cobalt High-Speed Steel. …
- Titanium. …
- Black oxide. …
- Zirconium Coating. …
- Diamond. …
- Other Tools Articles.
What is the function of power drill?
A power drill is a tool with an electrical motor that rotates a replaceable drill bit at your choice of speeds to create a hole in a variety of materials. The drill can also take screwdriver bits, to allow easier driving of screws through different materials.
