Whether you’re building new cabinets from scratch, preparing existing cabinets for fresh paint, or smoothing out imperfections before staining, choosing the best sander for sanding cabinets makes all the difference. After 40 years in professional cabinet work, I’ve discovered that the best sander for sanding cabinets isn’t what most DIYers think it is. Walk into any professional cabinet shop, and you’ll notice we don’t reach for orbital sanders when cabinet sanding needs to be done right. There’s a better tool that handles every cabinet sanding task faster and with superior results.
Why Professional Cabinet Makers Avoid Orbital Sanders
The woodworking community has convinced most DIYers that orbital sanders are the “safe” choice for cabinet work. This misconception costs countless hours and delivers mediocre surface preparation. Orbital sanders move in tiny circles, which sounds gentle, but this action actually creates micro-scratches that telegraph through paint and stain applications.
Professional cabinet shops abandoned orbital sanders for cabinet work because they simply don’t remove material efficiently. What takes an orbital sander 20 minutes per cabinet door, a proper sander accomplishes in 5 minutes with better surface quality. Whether you’re smoothing raw wood for initial finishing or preparing surfaces for new paint, time efficiency matters.
The real issue with orbital sanders goes beyond speed. Their random orbital action creates inconsistent scratch patterns that show through finishes, especially on hardwoods like oak and maple. Professional cabinet builders know that consistent, controlled sanding creates the foundation for flawless paint adhesion and even stain penetration.
The Hidden Problems with Orbital Sanders on Cabinet Work
Orbital sanders suffer from fundamental design limitations that make them unsuitable for serious cabinet sanding. Their small 5-inch pads require excessive passes to cover cabinet door centers, increasing the risk of uneven sanding and creating lap marks where passes overlap. This becomes especially problematic when preparing cabinets for paint, where surface uniformity is critical.
Heat buildup presents another problem with orbital sanders during cabinet projects. Extended sanding sessions cause the pads to heat up, which can burn delicate wood fibers and create surface defects that show through stain or paint. Professional sanders dissipate heat more effectively through their larger pads and superior engineering.
Cabinet work demands controlled aggressiveness for various tasks – removing mill marks from new wood, smoothing brush marks between paint coats, or leveling minor surface imperfections. Orbital sanders lack this controlled power, forcing multiple passes and extending project timelines unnecessarily.
The Best Sander for Sanding Cabinets: PORTER-CABLE 7346SP
PORTER-CABLE Sander with Polishing Pad, 4.5-Amp, 6-Inch Polisher, 2,500-6,800 OPM, Corded (7346SP)
The PORTER-CABLE 7346SP represents everything orbital sanders should be but aren’t. Its 6-inch polishing pad covers 44% more surface area than standard 5-inch orbital sanders, dramatically reducing sanding time for cabinet doors, face frames, and panels. The variable speed control ranges from 2,500 to 6,800 OPM, providing the power needed for aggressive material removal while maintaining finesse for final surface preparation.
This sander’s polishing action differs fundamentally from orbital sanders’ random movement. The controlled polishing motion creates consistent scratch patterns that accept paint and stain evenly, providing superior finish adhesion. Professional cabinet shops rely on this predictable action for the consistent results that separate amateur work from professional quality.
The 4.5-amp motor delivers sustained power that maintains consistent performance throughout entire cabinet projects. Unlike orbital sanders that bog down under pressure, the Porter-Cable maintains its selected speed regardless of sanding pressure, ensuring uniform results whether you’re working on a single cabinet door or an entire kitchen’s worth of cabinets.
Why This Sander Handles All Cabinet Sanding Tasks
The Porter-Cable 7346SP serves as a one-tool solution for complete cabinet sanding projects. Its 6-inch pad handles large door centers and face frames efficiently, while careful technique allows it to sand detailed areas that would typically require additional tools. This versatility eliminates tool changes whether you’re preparing new cabinet components or refreshing existing ones.
For new cabinet construction, this sander removes mill marks and prepares raw wood surfaces for staining or painting in a fraction of the time orbital sanders require. When working on existing cabinets, it smooths brush marks between paint coats, removes minor scratches, and prepares surfaces for fresh finishes with professional efficiency.
Professional Technique: How to Use the Porter-Cable Like a Pro
Running the Porter-Cable at full speed with 120-grit sandpaper handles 90% of cabinet sanding situations. This setup removes mill marks from new wood efficiently while providing the surface texture needed for optimal paint and stain adhesion. Lower speeds serve specific purposes, but full speed delivers the best balance of efficiency and control for general cabinet work.
The cardinal rule with this sander is constant motion. Its powerful polishing action can create gouges and low spots if held stationary, even briefly. Professional technique involves smooth, overlapping passes that maintain consistent pressure while never dwelling in one location. This approach requires practice but delivers superior surface preparation once mastered.
Proper pressure application makes the difference between professional and amateur results. Let the sander’s weight and aggressive pad do the work rather than applying excessive downward pressure. Heavy pressure causes the motor to bog down, reduces efficiency, and increases the risk of surface damage on your cabinet components.
Sanding Different Cabinet Components
Cabinet doors require technique that accounts for panel construction and grain direction. The Porter-Cable’s large pad handles flat door centers beautifully, removing mill marks and preparing surfaces for paint or stain application. Raised panel doors need careful attention to grain direction changes and surface transitions.
Face frames demand consistent technique across rails and stiles with different grain orientations. Professional approach involves following the grain direction for each component while maintaining uniform scratch patterns. The Porter-Cable’s polishing action accommodates these requirements better than orbital sanders’ inconsistent movement.
Cabinet boxes and shelves benefit from the sander’s efficient coverage of large flat surfaces. Whether you’re smoothing plywood edges before painting or preparing solid wood shelves for staining, the 6-inch pad covers ground quickly while maintaining surface quality.
Understanding Grit Selection for Cabinet Sanding
Professional cabinet sanding typically starts and ends with 120-grit sandpaper for most situations. This grit removes mill marks and surface imperfections efficiently while providing the surface texture that paint and stain products require for optimal adhesion. Finer grits may seem logical, but they often create surfaces too smooth for proper finish bonding.
Coarser grits like 80 or 100 serve specific purposes when dealing with heavily damaged cabinet surfaces or significant imperfections. However, these aggressive grits require careful technique to avoid surface damage and typically necessitate progression through finer grits to achieve finish-ready surfaces.
The key insight from professional practice is that grit progression often wastes time without improving final results for most cabinet work. Starting and finishing with 120-grit handles most cabinet sanding situations effectively while maintaining efficient workflow and consistent surface preparation.

Safety Considerations for Power Sanding Cabinet Projects
Professional-grade sanders demand respect and proper safety precautions during cabinet work. Always wear safety glasses and dust masks rated for fine particles. Cabinet sanding generates tremendous amounts of airborne dust that poses respiratory hazards without proper protection, especially in enclosed spaces like kitchens.
Hearing protection becomes essential during extended sanding sessions with powerful tools. Professional sanders operate at sound levels that can cause hearing damage during prolonged cabinet projects. Quality ear protection maintains safety while allowing communication and awareness of tool operation.
Proper ventilation and dust collection protect both health and work quality during cabinet sanding. Fine sanding dust settles on cabinet surfaces and can contaminate finishes if not controlled effectively. Professional approach includes both personal protective equipment and environmental controls.
