Essential for automotive technicians, fabricators, and bodywork professionals who demand precision control and operator comfort during extended sanding operations.
Key Features & Benefits
| Feature | Benefit |
|---|---|
| Reduced Operator Fatigue | Precision-balanced motor and comfortable molded grip absorb vibration by 50% and reduce noise levels, enabling extended work sessions without the hand strain typical of unbalanced sanders. The 97-degree head angle provides natural wrist positioning on vertical surfaces, reducing muscle fatigue during overhead and side panel work. |
| Variable Speed Control | Variable speed trigger delivers precise control over sanding aggression from 0–15,000 RPM, preventing oversanding and reducing rework time by up to 30%. This is essential for automotive paint prep and delicate blending where consistent material removal and finish quality matter most. |
| Dual Mount Versatility | Switch seamlessly between direct mount for maximum visibility and control, or collet mount for extended reach in confined spaces up to 6 inches deeper than standard configurations. Ideal for open panel work and tight engine bay access without tool changes. |
| Professional Grade Construction | Lightweight 2.2 lb aluminum body with 0.45 HP motor delivers consistent performance at ~4 CFM air consumption while maintaining portability for all-day use. Precision engineering ensures reliability in demanding shop environments with minimal maintenance. |

Frequently Asked Questions
How does this compare to orbital sanders for automotive work?
This disc sander offers superior material removal rates and better access to tight spaces compared to orbital sanders. While orbitals provide smoother final finishes, this pistol grip disc sander excels at paint removal, weld cleanup, and spot repairs where aggressive cutting is needed.
What type of sanding discs work best with this tool?
Use 3" Roloc or hook-and-loop sanding discs rated for at least 15,000 RPM. 3M Roloc discs provide the most secure attachment and are engineered for this tool’s performance characteristics.
Is this disc sander suitable for woodworking applications?
Yes—great for detail sanding, edge finishing, and surface prep. Variable speed lets you tune to different woods and grain patterns, and the compact head is ideal for curves and tight spots.
What air pressure and CFM requirements does this sander need?
Operate at 90 PSI with approximately 4 CFM at working pressure. Ensure your compressor can maintain pressure and use a quality regulator for best performance and longevity.
