RYOBI 18V Corner Cat Finish Sander - Compact Precision Tool

Our review of the RYOBI 18V Corner Cat Finish Sander finds it best suited to hobbyists, furniture makers, and DIYers who need a small, controllable tool for tight spots. The single biggest reason to buy is its compact triangular base combined with 50% reduced vibration versus the prior model, which together deliver more precise sanding and a finer finish in corners, ledges, and detailed trim work. The tool is lightweight and easy to handle, making it a practical choice when access and control matter more than full-scale aggressive stock removal.

Key Features

• Compact Triangular Base: The pointed base lets users reach tight corners and narrow spaces that round or rectangular sanders cannot access.
• Compact Size: The small form factor improves grip and control for detail sanding and keeps fatigue low during longer tasks.
• 50% Reduced Vibration: Lower vibration than the previous model increases user control and helps produce a smoother, more consistent finish.
• Hook & Loop Sandpaper Attachment: The easy hook and loop system speeds pad changes and ensures sandpaper stays secure during use.
• Included Samples and Manual: Sample sandpaper and an operator manual are included so users can start on small projects right away.

Who It's For

The Corner Cat is ideal for woodworkers, furniture refinishers, and DIY homeowners who often work on tight corners, moldings, and small surfaces where a full-size sander is awkward. Its compact design and reduced vibration suit precision work like detail sanding and final finishing.

Those who need heavy material removal, continuous long runtime, or an all-day production tool should look elsewhere; battery and charger are sold separately, and users relying on high amperage batteries for extended runtime may find a larger random-orbit sander more appropriate.

Pros & Cons

Pros

• Excellent access to corners and tight spaces thanks to the triangular base.
• Reduced vibration provides better control and a finer finish on delicate work.

• Compact size fits comfortably in hand and is suitable for detailed sanding tasks.

Cons

• Battery and charger are not included, and battery life depends on the pack used.
