The Pro-Graad 5.5" Long Reach 1/4" Collet Extension Tool is a heavy-duty solution designed for professionals who need reliable access to deep, tight, or awkward spaces. With its extended 5.5-inch length, this tool enables die grinders to reach areas that are typically inaccessible with standard extensions—making it an essential addition for engine porting, precision grinding, and maintenance work in automotive, industrial, and construction settings. Built with a secure 1/4” collet, the extension holds carbide burrs, drill bits, and rotary tools firmly in place. This stability not only ensures precise performance during detailed tasks like deburring, polishing, and finishing, but also reduces the risk of tool slippage or operational errors. The added reach gives users better leverage and control, helping to produce cleaner results with less effort. Comfort and safety are also enhanced thanks to the tool's extended length. Operators can maintain a safer distance from flying debris and hot surfaces, lowering the chance of accidental contact or injury. Additionally, it allows for a more ergonomic working position, which minimizes fatigue and hand strain—especially important during long or repetitive jobs. Whether you're navigating around engine blocks, inside confined equipment housings, or working along tight weld seams, the Pro-Graad 5.5" Extension Tool makes it easier to complete tough jobs with precision and confidence. It's a perfect match for USA-made carbide burrs and various ¼” shank accessories, delivering dependable performance in demanding environments. If you're serious about your craft and need a tool that helps you work smarter and safer, this long-reach collet extension is a must-have in your toolkit.
