Lathe Tool Combined ER Collet Chuck AA — ER11, ER16, ER20, ER25, ER32 Spring Collet Tool Holder for CNC Milling, Drilling, Engraving, Tapping (ER32 AA 12PCS Set 3) A versatile ER collet chuck system designed for precision clamping and reliable tool holding in a variety of machining tasks. The combined ER collet chucks (AA model) accept standard ER collets and are intended for CNC milling, drilling, engraving, tapping, and general lathe operations. This listing is the ER32 AA 12PCS Set 3; the product family also covers ER11, ER16, ER20, ER25 and ER32 sizes. Key benefits Versatility: Works across common machining applications — milling, drilling, engraving and tapping — reducing the need for multiple dedicated holders. Secure, concentric clamping: Spring ER collet design provides consistent axial grip on tool shanks for stable cutting and reduced tool movement during use. Easy tool changes: Straightforward collet insertion and tightening speed up setup and tool swap times on the floor or in a production environment. Broad compatibility: Fits the ER collet system and the AA shank/toolholder configuration referenced in the model name, making it compatible with many CNC and lathe setups. What you get Product family: Lathe Tool Combined ER Collet Chuck AA Collet sizes referenced: ER11, ER16, ER20, ER25, ER32 Specific listing: ER32 AA 12PCS Set 3 Type: Spring collet tool holder for CNC, milling, drilling, engraving, tapping Features and attributes Functionality: Springtype ER collet chuck provides axial and radial clamping for roundshank tools and adapters. Compatibility: Designed for standard ER collet sizes (ER11–ER32) and the AA shank configuration in the product name. Use cases: Intended for CNC milling machines, drill presses, engraving and tapping operations, and lathe tool holding where ER collets are used. Performance: Built to deliver stable clamping during common machining operations, supporting accurate and repeatable tool positioning. Typical applications CNC milling: Securely hold end mills and cutters for light to mediumduty milling and profiling. Drilling and tapping: Provide repeatable concentric clamping for drilling and tapping heads to improve hole quality and thread alignment. Engraving and light turning: Enable precise tool holding for engraving cutters and light lathe operations where ER collets are used. Who should choose this product Machine shops and hobbyists that use ER collet tooling and need flexible, quickchange holders. Users who require a dedicated ER32 AA set (this listing) or who want compatibility with the ER11–ER32 ER collet system. Operators seeking reliable springcollet clamping for milling, drilling, engraving, and tapping tasks. Ordering note This listing specifies the ER32 AA 12PCS Set 3 variant. The product line includes ER11, ER16, ER20, ER25 and ER32 sizes; confirm the size and set variant you need before ordering. Care and handling Follow your machine and tooling manufacturer's instructions for mounting, torqueing, and collet selection. Inspect collets and chucks regularly for wear, debris, and correct seating to maintain concentricity and performance. Precision clamping for a wide range of machining tasks — ER collet compatibility, AA model identification, and the ER32 AA 12PCS Set 3 variant provide a practical solution for shops and hobbyists using ERsystem tooling.
