Model RT3L Tumbler is Heavy-Duty triple 1.5lb barrel rotary tumbler with direct drive motor Ideal for tumbling gemstones or glass.
SPECIFICATIONS HIGHLAND PARK RT3L ROTARY TUMBLER FEATURES AND SPECIFICATIONS:
LOAD SIZE: 6 lbs of stone carried in two 3 lbs barrels
FRAME – Brushed heavy gauge 304 Stainless steel.
BARREL GUIDES - Adjustable barrel guides make it easy to get your barrels running smoothly every time and prevent barrel damage from the barrel rubbing on the frame.
MOTOR – Variable Speed High Torque Low Voltage brushless DC motor - Motor is mounted in a direct drive configuration which eliminates all the historical issues with belts and pulleys eliminating the problems of fiddling with the machine to get the right belt adjustment. The brushless DC motor has a much higher torque than conventional tumbler motors and generates much less heat because it operates on low voltage DC power. Additionally, this eliminates the electrical hazard associated with the conventional tumblers.
POWER SUPPLY - 110v to 24v adapter that supplies the low voltage power to the tumbler. Safer and reduces the heat that the motor will produce over other machines. BUSHINGS and SHAFTS- The bushings are machined from durable solid nylon rod and the shafts are made from 304 stainless steel.
BARREL – Durable molded rubber barrel with stamped 6061 Aluminum lid anodized red to minimize oxidation. Retention thumb-knob is solid brass for durability and long life.
SERVICABILITY - We designed this machine with the focus of producing a very reliable and easy to service machine.
