## Description

Jacobs Chuck professional duty chuck. 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. It is 1/2-20 mount. 0.063-incehs minimum capacity and 0.5-inches maximum capacity. Measures 1-23/32-inches diameter by 3-inches close length and 2-19/64-inches open length.

Review: Great quality - As always, Jacobs delivers quality. 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.

### ⭐⭐⭐⭐⭐ 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. No real comments about that.
