What Size Orbital Polisher for Car Detailing?

Choosing the right orbital polisher can feel overwhelming, especially with terms like “throw” and “dual-action” being thrown around. Understanding what size orbital polisher is best for car detailing depends on your experience level, the type of detailing you plan to do, and the size of the vehicle you’re working on. This guide will break down everything you need to know about choosing the perfect orbital polisher for your detailing needs.

Understanding Orbital Polishers: DA vs. Rotary

Before diving into sizes, let’s clarify the two main types of orbital polishers: Dual-Action (DA) and Rotary. DA polishers are the go-to for most detailers, especially beginners. They move in a random orbital pattern, minimizing the risk of burning or swirling the paint. Rotary polishers, on the other hand, spin on a single axis and offer more cutting power but require a skilled hand to avoid damaging the paint. This article will focus on DA polishers, the safer and more versatile option for most car detailing applications.

What Does “Throw” Mean?

“Throw” refers to the diameter of the orbit the polishing pad makes on a DA polisher. This measurement is crucial as it determines the size of the area you can effectively polish at a time. Larger throws cover more ground quickly, while smaller throws offer more precision in tighter areas.

Common Orbital Polisher Sizes and Their Uses

DA polishers are typically categorized by their throw, with the most common sizes being 3-inch (75mm), 5-inch (125mm), and 6-inch (150mm).

3-Inch (75mm): Ideal for spot correction, intricate details, and smaller panels like bumpers and spoilers. Its smaller size allows for precise work and maneuverability in tight spaces.
5-Inch (125mm): The most versatile and popular size for car detailing. It balances coverage and precision, making it suitable for both large panels and smaller areas.
6-Inch (150mm): Best for large, flat panels like hoods, roofs, and doors. It covers more ground quickly but can be less maneuverable in tighter spaces.

Choosing the Right Size: Factors to Consider

Selecting the ideal orbital polisher size depends on several factors:

Your Detailing Experience: Beginners are generally recommended to start with a 5-inch DA polisher due to its versatility and forgiving nature. More experienced detailers might opt for a 3-inch for intricate work or a 6-inch for larger vehicles.
Types of Detailing Jobs: For regular maintenance and light paint correction, a 5-inch is usually sufficient. However, for heavy correction or working on larger vehicles, a 6-inch polisher might be more efficient. For spot correction and detailing intricate areas, a 3-inch polisher is the best choice.
Vehicle Size: Larger vehicles like trucks and SUVs benefit from a 6-inch polisher, while smaller cars are better suited for a 5-inch or 3-inch.

Why a 5-Inch Orbital Polisher is Often the Best Starting Point

For many car detailing enthusiasts, the 5-inch DA polisher strikes the perfect balance. It’s versatile enough to handle most detailing tasks, easier to control than a 6-inch, and still provides ample coverage.
