Makita Genuine 150178-0 Torque Limiter Complete for Makita 8406 Diamond Core Drill

The Makita 150178-0 Torque Limiter Complete is a genuine OEM replacement part for the Makita 8406 Diamond Core Drill, restoring the machine's built-in overload protection when the original assembly is worn or damaged. Constructed from steel and alloy components, this assembly employs a slip-clutch mechanism to regulate drive torque during core drilling. When a diamond core bit binds in masonry or similar materials, the limiter disengages at a preset torque threshold, protecting the gearbox and motor from overload stress and reducing the risk of sudden kickback. As a direct-fit, factory-specified replacement, the 150178-0 is designed to reinstate the performance characteristics of the original part without modification. For contractors and tradespeople who depend on the 8406 for demanding site work, fitting a genuine Makita component ensures consistent, reliable drilling performance and helps minimise unplanned downtime caused by drivetrain damage.
