Grizzly Industrial Pin Jaws For 4 Jaw Chuck Review

Let’s Talk About Grizzly Industrial Pin Jaws For 4 Jaw Chuck

As a seasoned woodturner with over a decade of experience, I’ve relied on various chucking methods to secure workpieces. When I first encountered the Grizzly Industrial Pin Jaws For 4 Jaw Chuck, I was immediately intrigued by their potential to simplify bowl mounting. These jaws are specifically designed to expand into a 1″ diameter recess, offering a dovetailed lip for a secure grip.

The promise of a quick, reliable method to mount bowls without relying on external tenons was immediately appealing. Upon unboxing, I noted the solid steel construction, giving me confidence in their durability.

I’ve used similar expanding chucks from other manufacturers such as Nova and Oneway. However, the price point of the Grizzly Industrial jaws combined with the Grizzly Industrial reputation for decent quality made them worth trying.

Real-World Testing: Putting Grizzly Industrial Pin Jaws For 4 Jaw Chuck to the Test

First Use Experience

My initial test involved turning a small cherry bowl. I used a forstner bit to drill a 1″ recess into the bottom of the bowl blank. After fitting the Grizzly Industrial Pin Jaws For 4 Jaw Chuck into my existing 4-jaw chuck, I carefully expanded the pin jaws into the recess.

The grip felt surprisingly secure, even at moderate speeds. I tested the stability by applying pressure with my gouge. There was minimal vibration or slippage. I also tested with slightly out-of-round stock to observe if the chuck could handle the imbalance.

Extended Use & Reliability

After several weeks of consistent use, the Grizzly Industrial Pin Jaws For 4 Jaw Chuck have proven to be a valuable addition to my workshop. I’ve used them on various wood types, including maple, walnut, and exotic hardwoods. The jaws have held up exceptionally well.

There are minimal signs of wear and tear despite repeated use and clamping force. Maintenance is straightforward; a quick wipe-down with a dry cloth after each use keeps them clean and free of debris. Compared to my previous method of creating custom tenons, these jaws have significantly reduced setup time and material waste. They outperformed my expectations by providing a consistent and reliable grip for bowl turning.
