Chuck Reducer

What is a chuck reducer?

A chuck reducer is a speed reducer. It is mounted onto a chuck to control the power output of the drilling tool. It is usually seen on a drill. A drill is a tool that creates holes in a workpiece by providing force to the rotating drilling tool. A chuck is set behind to clamp the rotating tool; it prevents the rotating drilling tool from falling off the machine in such a high-speed revolution. A chuck reducer is installed between the chuck and the drilling tool so that the drilling tool's optimal performance can be reached.

A chuck reducer is made as a cylinder in conjunction with a clamp handle, which is used to hold the chuck reducer firmly when the drill is operating and help the chuck reducer set up on the drill or the chuck. Sometimes, between the reducer and the chuck, there is an adapter used to make the chuck reducer and the chuck with different diameters and shapes on each end fitting. By using the clamp handle, the chuck reducer can be tightly fixed on the adapter, and further connected with the chuck.


Why do we need a chuck reducer?

● to better control the force
 A chuck reducer is often applied with a type of hand tool, the drill, which can be held by the operator to make holes on the workpieces. In other words, the drill is completely controlled by manual force instead of being fixed on a larger device. With the high-speed torque of the rotating tool, a drill requires a higher controlling force as well as firmness. However, with merely the manual force, it is not stable enough to control this device. Therefore, a chuck reducer is made to deal with this problem. With the chuck reducer, it can not only act as a medium that connects the chuck and the drill but also play the role in providing a better controlling force of the drill.

 ● to reduce deviation
 A chuck reducer is used to keep a firm grip on the drilling tool while maintains its torque at the same time. The chuck reducer holds the drill with optimal firmness. The drilling tool will not easily fall off with the assistance of the clamp handle. Though the reducer extends the length of the drilling tool, it is not an obstruction that restricts the function of either the chuck or the drilling tool. Instead, it reduces the RPMs without deviating from the original torque.

RPM stands for revolutions per minute, which describes how fast the drilling tool rotates every minute. It can be difficult for the operator to control the drill when the rotation speed is too high, and it may further lead to deviation when drilling the workpieces. Therefore, the RPMs should be kept in an appropriate number. Besides, we don’t want the rotating speed to be lower down too much and lose its torque to drill. Applying a chuck reducer can avoid this problem because it can reduce the RPMs and maintain the optimal torque simultaneously. Therefore, it should be a necessary accessory when you use a chuck to hold the drill.


How to install a chuck reducer?

A chuck reducer can be installed on a drill with a chuck or without a chuck. Here we will focus on the installation with a chuck. To install a reducer on a drill with a chuck, a shank adapter is required. The shank adapter fits both the chuck reducer and the chuck on each end. Inside the chuck reducer, there is an input shank used to connect the reducer with the adapter.

The first step is to screw the shank adapter on the input shank. Next, fasten the shank adapter on the chuck. Then, set the clamp handle on the chuck reducer on the end that is close to the drill motor. Rotate the clamp handle and make it fix to the desired position, which is helpful for the operator to hold. The last step is to install the pilot drill, the hex washer, and the cutter on the opposite end against the adapter. Once these accessories are installed, the installation completes.


How to maintain a chuck reducer?

Between each use of the chuck reducer, appropriate maintenance is necessary because careful maintenance makes the tool live longer. To maintain a chuck reducer, you should apply lubricant on the surface as well as other accessories. By doing so, the reducer can be well-functioned for a long period.
