Hardin HD-4800 5-Inch Variable Speed Dual Action Random Orbital Polisher / Buffer 700W 1300-4800 RPM Replaces OEM# 7424, 7424SP Random Orbit Sander

The Hardin HD-4800 5" Variable Speed Dual-Action Random Orbital Polisher is designed for professional surface finishing on automotive, marine, and metal applications. Powered by a 700-watt, 6-amp motor, it delivers smooth, controlled performance across a variable speed range of 1,300–4,800 RPM. The dual-action orbiting system combines cutting power with a swirl-free finish, preventing holograms and burns even during extended use. Its balanced counterweight and ergonomic D-style handle ensure comfortable control for both horizontal and vertical polishing. A 5" hook-and-loop backing pad and light-cutting orange foam pad are included for quick pad changes and versatile detailing performance. Built with a reinforced housing, cast aluminum gearbox, and sealed motor, the Hardin HD-4800 provides dependable performance for professional detailers and demanding workshop environments.

Features:

  • Eliminates swirl marks and buffer trails using a dual-action random orbital motion that produces a smooth, uniform finish on automotive, marine, and composite surfaces.
  • Maintains precision and control with a variable speed range of 1,300–4,800 RPM, allowing seamless transitions from paint correction to final polishing.
  • Delivers steady torque through a 6-amp, 700-watt motor with constant-speed electronics that prevent RPM drop under load.
  • Minimizes heat buildup and surface damage with an orbital pattern that evenly distributes pressure during polishing and waxing.
  • Includes a 5" hook-and-loop backing pad as well as a light-cutting orange foam pad designed for polishing and surface correction on clear coat, gel coat, and painted finishes.
  • Enhances operator comfort with a balanced counterweight system and ergonomic D-style top handle for stable two-handed operation.
  • Enables precise speed selection with a 6-position variable dial conveniently placed for quick adjustments during use.
  • Built for professional shop and field environments with reinforced polymer housing, cast aluminum gearbox, and sealed motor resistant to dust and moisture.
