Review: Great product but no chuck key - The product is excellent but it did not come with a chuck key. Normally when Jacobs chucks are sold they come with a matching chuck key. When I contacted the seller after the product arrived they stated that the chuck does not come with a key. If that is the case then the seller should have stated that. On the Jacobs website they do not state that their chucks come with a key because it is standard practice to supply the proper chuck key. ## Features - Heavy duty models for threaded mounting; T.I.R. 0.004-Inch maximum at half capacity - Jaws center-ground for absolute straightness and alignment - One-piece sleeve eliminates crack between driving teeth often found in other designs - Through-hardened sleeve teeth, plus hardened nose and keyholes provide outstanding wear resistance - Each chuck 100-Percent inspected for performance and precision ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0000DCZ3Y | | Brand Name | Jacobs | | Capacity | 0.38 Inches | | Compatible Devices | Drilling Machine, Lathe, Milling Machine | | Customer Reviews | 3.0 3.0 out of 5 stars (1) | | Global Trade Identification Number | 00095456088597 | | Handle Type | keyed | | Included Components | Chuck Key | | Item Diameter | 0.38 Inches | | Item Weight | 0.88 Pounds | | Lock Type | Independent | | Manufacturer | Jacobs Chuck | | Manufacturer Part Number | 8859C | | Material Type | Alloy Steel | | Model Number | 8859C | | Thread Size | 1/2-20 UNC | | UPC | 095456088597 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Jacobs - **Compatible Devices:** Drilling Machine, Lathe, Milling Machine - **Item Diameter:** 0.38 Inches - **Item Weight:** 0.88 Pounds - **Material:** Alloy Steel ## Images ![Jacobs 8859C 32BA Heavy Duty Plain Bearing Keyed Chuck 1.0 to 0.0 Millimeter Capacity with 1/2- Inch 20 Threaded Mount - Image 1](https://m.media-amazon.com/images/I/51mRyNR-B5L.jpg) ## Customer Reviews ### ⭐⭐⭐ Great product but no chuck key *by G***3 on December 13, 2013* The product is excellent but it did not come with a chuck key.
