Chicago Pneumatic CP879C
Score: 72/100Rankings
The Astro Pneumatic 525C is a lightweight, reversible pneumatic drill designed for versatile drilling and driving applications with full power in both directions. Its moderate speed and moderate torque make it a balanced tool for general maintenance rather than heavy construction. It is best suited for professionals requiring a portable pneumatic drill where battery tools are impractical.
The Chicago Pneumatic CP879C is a specialized angle air drill designed for precision work in confined automotive and industrial spaces. Its main trade-off is limited torque output, making it unsuitable for heavy-duty large-hole drilling. It is best suited for professionals in body shops and maintenance who need maneuverability over raw power.
