MT3-ER32 18-Piece Collet Set with Chuck Spanner 2–20mm Clamping Range, Hardness 40-50HRC Thread M12 Precision Milling Drilling Tools for CNC, Lathe Engraving Machines

• 【Versatile Milling/Drilling】This collet chuck set includes 18 collets of different specifications, covering a wide clamping range of 0.08-0.79in (2-20mm).This versatility allows you to adapt to various tool diameters, whether you’re working with drills, end mills, reamers, or straight shank tools, making it an essential companion for both professionals and hobbyists in metalworking, woodworking, and other precision machining tasks
• 【High-Strength Materials】Crafted from high-quality steel and reinforced with aluminum alloy components, the set undergoes a quenching process to achieve a hardness of 40-50HRC.This combination ensures exceptional durability, wear resistance, and corrosion resistance, maintaining structural integrity during heavy-duty operations and minimizing deformation, so it can reliably withstand the rigours of frequent use in demanding workshops
• 【Precision Serrated Design】The serrated collet and precisely machined card slot are engineered to prevent tool deviation during clamping.This design ensures smooth, stable milling and drilling, delivering high accuracy of 0.0006" to maintain tool alignment and reduce errors.Clear size markings on each collet further streamline selection, saving time and enhancing workflow efficiency
• 【Secure Storage】All components—collet chuck, 18 collets, spanner, and clamping nut—are housed in a sturdy aluminum alloy carrying case.The interior is lined with EVA foam to keep collets organized, separated, and protected from slipping or damage.Rounded edges on the case add practicality by preventing accidental scratches and improving aesthetics, making it easy to carry and store at any workplace
• 【Simplified Cleaning & Maintenance】The collet chuck set features a smooth surface and straightforward structure, enabling quick and easy cleaning with just a damp cloth.This design minimizes downtime for maintenance, ensuring the tool remains in optimal condition with minimal effort.Combined with its lightweight net weight of 8.82lbs and compact case size (10.637.876.3in), it’s ideal for on-site work where convenience and reliability are key
