This makes them worth it considering you’ll be holding this machine for some time with your hands.
Why are brushless drills so expensive?
These magnets don’t come cheap since they are made from rare-earth metals like neodymium that doesn’t come cheap too. Their demand makes them very expensive. So why not use cheaper alternatives? It’s because cheaper permanent magnets are not as strong and permanent as the current magnets . This will make the drill bigger and heavier to provide the same torque, and that will increase the cost. As a result, the weight will increase and the performance will be compromised. This will lead to fatigue at a higher working rate.
What is the difference between a brushless motor and an outrunner motor?
There are two types of motors – Inrunner and Outrunner. The difference between the two is where the rotor is located. Inrunner motors have the rotor on the inside while the Outrunner motor has it on the outer side. A brushless drill mostly uses an Inrunner motor which has a restricted space inside. This forces its windings to be installed by hand which is a difficult job and takes a lot of time. All these factors combined make them that expensive.
Why is friction important in a drill?
Friction reduces a machine’s lifespan due to wear and tear. Due to lack of friction , less heat which is a catalyst of early breakdown is generated internally keeping the drill cool regardless of the speed it runs at.
