Durable, precise ER16 collet chuck designed for consistent performance and broad compatibility Key benefits Built to last: manufactured from high-quality, durable materials to withstand regular shop use and provide long service life. Fits your tools: compatible with all ER16 collets, so it integrates easily into existing ER16 tool setups. Accurate results: minimal runout (TIR) of 7.6 cm minimizes wobble for more consistent drilling and milling. Flexible clamping: wide holding range from 3/16" to 1/2" (approx. 4.76 mm to 12.7 mm) covers a variety of tool shank sizes. How this product solves problems Reduces tool vibration and runout-related errors, producing cleaner holes and more accurate cuts. Eliminates the need for multiple specialty chucks by accepting any ER16 collet, simplifying tool inventory and changeover. Durable construction lowers the risk of premature wear, helping maintain concentricity and reducing downtime. Typical applications CNC milling and routing: hold small end mills and drill bits with improved concentricity for fine-detail cuts and engraving. Bench drilling and hobbyist work: stable clamping for precision drilling in metals, plastics, and composites. Light production and prototyping: fast changeovers between ER16 collets make this suitable for short-run machining and iterative setup work. Technical details (as specified) Material: high-quality, durable construction (material of manufacture per original specification). Compatibility: works with all ER16 collets. Runout: minimal chuck runout (TIR) 7.6 cm. Clamping range: 3/16" to 1/2" (approx. 4.76 mm to 12.7 mm). Purchase considerations Ideal if you already use ER16 collets and need a robust, accurate chuck to improve part quality. Check that the stated runout and clamping range meet your tolerance and tool-size requirements before ordering.
