Can confirm this is a direct replacement for the Milwaukee factory chuck on a 0299-20 heavy duty drill. The inside retaining screw is a 3/16” left hand thread allen. I found it easiest to chuck up a 12mm impact grade allen socket and remove the chuck with an impact. Lefty loosy (normal right hand thread so counter clockwise to remove chuck). Chuck does include complete instructions and they work for this replacement. R Review: Great chuck - Used this to replace old metal heavy duty Chraftsman drill chuck, I've been fighting g with for years, as no key worked properly. Installed easily using impact drill to remove old chuck. Works great with smooth action. ## Features - It has industrial quality - Through hardened jaws provide hard, durable gripping surfaces - One piece sleeve eliminates crack between driving teeth often found in other designs - Fluted sleeve finish - Each chuck 100 percent inspected for performance and precision ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0000DCZ46 | | Best Sellers Rank | #223,290 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #228 in Power Drill Chucks | | Brand Name | JACOBS | | Capacity | 0.5 Inches | | Compatible Devices | Drilling Machine | | Customer Reviews | 4.5 4.5 out of 5 stars (190) | | Global Trade Identification Number | 00095456310520 | | Handle Type | hand-tightened | | Included Components | 72 Jacobs Branded Item | | Item Diameter | 1.72 Inches | | Item Type Name | Drill Chuck | | Item Weight | 0.01 Pounds | | Lock Type | Possible keyed lock | | Manufacturer | Jacobs Chuck | | Manufacturer Part Number | 31052D | | Material Type | Stainless Steel | | Model Number | 31052 | | Thread Size | 1/2-20 | | UPC | 095456310520 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** JACOBS - **Compatible Devices:** Drilling Machine - **Item Diameter:** 1.72 Inches - **Item Weight:** 0.01 Pounds - **Material:** Stainless Steel ## Images ![Chuck 31052D Professional Duty Chuck, 1/2-20 Mount, 0.5" Maximum Capacity, 1-23/32" Diameter x 3" Closed Length - Image 1](https://m.media-amazon.com/images/I/61ar9BVIhhL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great quality *by R***T on February 24, 2026* As always, Jacobs delivers quality.

Installed easily using impact drill to remove old chuck. Works great with smooth action. ### ⭐⭐⭐⭐⭐ Nice upgrade. Worth the money *by D***L on May 19, 2024* When doing hundreds of holes, my drivers tend to drop the pre-drill bit every 20 holes or so. I wanted at least one driver with a keyed chuck. This fits perfectly. It is heavier, and did change the balance a bit. Jacob's is an established name with quality products.
