Common Power Tool Replacement Parts

Accessories & Bits

Accessories and bits are known to wear out over time. Sometimes they chip and break or get stuck in whatever it is that you’re working on. You must make sure that you’re choosing the right one for the job and for the tool . 


Your cordless tool batteries and chargers will eventually need to be replaced, especially if you are using them every day. Batteries and chargers  are a common replacement items. If you’re storing the batteries where the temperature is too high or too low, heat or cold will burn out the cells that is in it and the batteries can die. Make sure you unplug your charger once the battery is fully charged .


Running your tool high or for anything other than its intended use could cause the bearings to wear out sooner. Bearings are what make the movement in your power tool possible. These will eventually wear out over time from standard use. When they wear down, they may cause the tool to overheat, make high-pitched squealing noises or stop working altogether.

Carbon Brushes

Carbon brushes are the component that allows the electrical current to flow through the tool and to its rotating parts. Replacing them is very common to power tool repairs. The motor brushes are normally sold as a pair because they  wear out evenly  just from normal use. To know if you need new brushes, your tool might have trouble starting, run low or it might not start at all. You may also see sparks during use of the tool.


There are two major types of drill chucks, keyed and keyless drill chucks. The most likely reason your drill bit keeps coming loose is the chuck on your drill is worn out and not locking properly. To fix the issue you can replace the chuck. Don't forget to oil and clean the chuck once in a while, they will seize up if you don’t.

Drive Belts

Power tools with motors most likely have belts to operate them. Drive belts are predisposed to dry rot, can crack and loose elasticity. They are common replacement parts because of the natural wear and tear that will occur.

Power Cords

Power cords get damage with regular use. Overtime the rubber unravel through constant rubbing and cause the wiring to be exposed. You may also end up with bent or broken prongs. This is very unsafe and should be replaced immediately.

Power Switches

A power switch controls the flow of power to an electric device. It is extremely important to understand that the design of power tool switches varies greatly from switch to switch. When trying to use a tool and the switch will not power on can be frustrating. Worse is when it will run on and off again. Using the tool frequently can cause the switch to burn out or wear out fast.
