Katool RL-8500 - Professional Combination Brake Lathe with DC Servo Motor Technology

The Katool RL-8500 is a professional combination bench brake lathe engineered for automotive repair shops to resurface brake rotors, drums, and flywheels. Utilizing independent DC servo motors, this gearless design eliminates traditional mechanical transmissions to reduce vibration. The machine accommodates both standard and composite rotors through a Quick-Change Adapter-Plus system with comprehensive adapter package coverage.

Gearless DC servo motor design eliminates mechanical transmissions for zero gearbox maintenance
Handles rotors up to 17 inches (432 mm) diameter and drums up to 28 inches (711 mm)
Quick-Change Adapter-Plus system enables sub-30-second rotor/drum changeover
Accommodates composite rotors with center holes from 4 to 6.25 inches (102-159 mm)

Key Features & Benefits

Gearless DC Servo Motor Architecture

The RL-8500 employs independent DC servo motors for both cross-feed and spindle-feed drives, completely eliminating mechanical gearboxes, belts, and transmission systems. This direct-drive architecture removes wear-prone components and provides vibration-free power delivery for smoother rotor finishes.

Infinitely Variable Feed Rate Control

The servo motor system delivers continuous adjustment of cutting speeds rather than fixed gear settings. Technicians can fine-tune feed rates anywhere within the operating range to optimize parameters for aggressive rough cuts or precision finish passes without stopping the machine.

Quick-Change Adapter-Plus System

The Quick-Change Adapter-Plus system features integrated spring mechanisms that eliminate conventional bell clamps and centering cones. Adapters install with simple quarter-turn movements, securing rotors and drums with automatic spring-loaded centering that compensates for minor variations in hub dimensions.

Comprehensive Composite & Standard Rotor Compatibility

The included adapter package covers standard rotors with center holes from 2-5/32 to 4 inches and composite rotors with center holes from 4 to 6.25 inches. This dual-range capability handles domestic and foreign passenger car and light truck applications without requiring additional adapter purchases.

Tapered Spindle Bearing System

The RL-8500 utilizes massive tapered spindle bearings rather than standard cylindrical bearings. This distributes radial and axial loads across a larger contact area, providing superior stability and rigidity when machining heavy truck drums approaching the 28-inch capacity.

Applications & Use Cases

  • Automotive Repair Shops: Rotor and drum resurfacing for domestic and foreign vehicles.
  • Fleet Maintenance: High-volume drum reconditioning for commercial fleets.
  • Performance Shops: Composite rotor resurfacing for European imports.
  • Machine Shops: Flywheel resurfacing for engine rebuilds and clutch service.
  • Heavy Equipment Repair: Brake drum machining for light commercial equipment.
