Let’s Talk About Grizzly Industrial Adjustable Parallel Set
The Grizzly Industrial Adjustable Parallel Set is a six-piece kit designed to provide machinists and hobbyists with a versatile solution for setting up workpieces in milling machines, lathes, and other precision machining applications. Manufactured by Grizzly Industrial, these parallels allow for creating precise heights between 3/8″ and 2-1/4″, making them essential for ensuring accurate cuts and consistent results.
I needed to accurately and repeatedly machine parts to specific thicknesses. Traditional solid parallels often require a large collection to achieve different setups, and I was looking for a more efficient and space-saving solution.
Upon unboxing, I was immediately impressed by the solid feel of the Grizzly Industrial Adjustable Parallel Set. The machined and ground faces look meticulously crafted, promising a high degree of accuracy. The locking set screws inspire confidence that settings will be maintained during use.
While I considered individual solid parallels from brands like Starrett and Mitutoyo, the adjustable nature of this set ultimately won me over. I felt like the cost justified the utility provided by one kit providing the range of many expensive fixed parallels. I was excited to see if the build quality and accuracy lived up to my expectations.
Real-World Testing: Putting Grizzly Industrial Adjustable Parallel Set to the Test
First Use Experience
I first tested the Grizzly Industrial Adjustable Parallel Set when milling a series of aluminum brackets for a custom electronics project. I used them to elevate the brackets in my milling vise, allowing me to machine features on the underside without interference. The parallels were instrumental in maintaining a consistent height across all the brackets, leading to a professional finish.
The machining environment is often prone to lubricant and metal chip contamination. Even with these conditions, the locking set screws held their settings, and the parallels did not slip, allowing me to focus on the task. I didn’t have to constantly recalibrate or worry about the workpiece shifting.
The ease of use was immediately apparent. It only took a few minutes to dial in the desired height using a dial indicator and then lock the set screws.
After my first project, I realized just how much time this set saves compared to fumbling around trying to find the right combination of fixed parallels.
Extended Use & Reliability
After several months of regular use in my machine shop, the Grizzly Industrial Adjustable Parallel Set continues to perform admirably. The hardened steel construction has held up well, showing minimal signs of wear and tear, despite frequent contact with cutting fluids and abrasive materials. Their ability to consistently and repeatedly provide exact spacing is still very useful to my workflow.
While the surfaces have picked up some minor scratches from handling, the precision-ground faces remain flat and accurate. The locking set screws continue to function flawlessly, preventing any unwanted movement during machining operations. I have no cause to doubt the longevity of the tools.
Cleaning the parallels is a simple task. A quick wipe-down with a shop towel and some solvent removes any accumulated grime and keeps them in good working order. They are still as useful as they were on day one.
Compared to my previous reliance on shims and makeshift setups, the Grizzly Industrial Adjustable Parallel Set has significantly improved my machining efficiency and accuracy. I haven’t looked back.
