💡 What factors determine proper clearance for a rotary tool dust extraction seal?
A quality spindle brush gasket maintains negative pressure inside the motor housing while tolerating slight shaft wobble.
- Size the bristle diameter to leave zero gap around the mounting collar
- Check the packing density to block fine particulate without overheating the cutting bit
- Swap the strip out when stiffness drops too low to hold back heavy chip loads safely
