Most are belt driven and have a step down pulley on the motor and the drill. Changing the groove the belt is in changes the speed of the drill. Small groove on the motor and large on the drill will give you the slowest speed.
The speed of a drill is defined as how many RPM's of the chuck. The TORQUE of a drill is defined as how many "ft/lbs" the chuck can transfer to a drill bit. Imagine the drill has a pulley connected to the chuck and the pulley has a radius of 1 ft. Connect a string to the pulley and see how much weight the drill can lift. If the drill could lift 25 pounds using that 1 ft radius pulley, it is developing 25 ft/lbs of torque. The weight may be lifted very slowly or very rapidly, depending on the RPM's of the chuck, but the torque will be determined by how much weight the drill would lift. Both are important characteristics of a drill. If the motor is weak, the manufacturer may use gearing to provide more torque, but if the chuck is turning slowly, you won't get much work done. If the motor is larger, the manufacturer may not need to use gearing to give you the same torque.
No, this is not a new feature. Sounds like you are simply not tightening the chuck enough. - If you are, and it still happens then the chuck is faulty, -take it back for another.
A drill works by rotating a drill bit to create holes in materials. The key components that enable it to function effectively are the motor, chuck, gears, and trigger. The motor provides power to rotate the drill bit, the chuck holds the drill bit in place, the gears control the speed and torque, and the trigger allows the user to control the drilling action.
An electric drill has a small electric motor inside, driving a series of gears. The power from the gears turn a chuck, which holds the bit placed into it thereby drilling a hole.
When buying a drill, consider factors such as the type of projects you will be using it for, the power source (corded or cordless), the drill's speed and torque, the chuck size, the ergonomics and weight of the drill, and the availability of additional features like a hammer function or adjustable clutch settings.
To use a drill as a router for woodworking projects, you can attach a router bit to the drill chuck and secure it tightly. Adjust the drill speed to a suitable setting for routing, and then guide the drill along the wood surface to create the desired shape or groove. Be sure to practice proper safety precautions and techniques when using a drill as a router.
This variable speed drill is for drilling different diameter chose different speeds. Workpiece material in the drill speed is important.

variable speed drill No. The correct answer is: Variable Speed Reversing, meaning it has a switch that lets you run the drill clockwise or counterclockwise, at any speed from 0 RPM to the maximum rated speed for the drill in question.
A drill works by rotating a drill bit to create holes in materials. Its main components include a motor that powers the rotation, a chuck that holds the drill bit in place, a trigger to control the speed, and gears to transfer power efficiently. These components work together to enable the drill to function effectively.
To use a Phillips drill bit for woodworking projects, make sure to choose the correct size bit for the screw you are using. Secure the bit in the drill chuck and set the drill to the appropriate speed. Hold the drill perpendicular to the wood surface and apply steady pressure while drilling to create a clean and precise hole for the screw.
A hand drill can be various things, such as an old fashioned S shaped drilling device that you turn by hand, or a straight drill with a geared wheel which you turn to rotate the bit. In more modern terms,a hand drill is aa electric motor in plastic case that has a chuck in front of it where you can fit drill bits and have the motor turn the bit at high speed.
