Grizzly Industrial Thin Parallel Set Review

How I Used the Grizzly Industrial Thin Parallel Set and What I Found

As a seasoned gear and equipment specialist with over a decade of putting tools through their paces in diverse environments, I’ve learned that the humble parallel is a foundational element in countless precision tasks. I was in the market for a reliable set of thin parallels for my workshop, specifically for tasks requiring fine adjustments and consistent support under my milling vise. The Grizzly Industrial Thin Parallel Set, with its promise of hardened and ground steel, caught my eye.

My current bench had a collection of mismatched parallels, a hodgepodge acquired over years of projects, and they were beginning to show their age and inconsistency. This often led to frustrating setups and a need for constant shimming, eating away at valuable machining time. I considered a few higher-end, bespoke sets, but for the general-purpose work I do, their cost seemed prohibitive. The Grizzly Industrial offering presented a compelling balance of quality and affordability.

Upon receiving the Grizzly Industrial Thin Parallel Set, my initial impression was one of solid, no-nonsense craftsmanship. They felt substantial and precisely manufactured, a welcome contrast to some of the softer, less accurate parallels I’d encountered. This immediate sense of quality offered a quiet promise of reliability.

Real-World Testing: Putting Grizzly Industrial Thin Parallel Set to the Test

First Use Experience

I primarily tested this set in my home workshop, focusing on milling operations where precise fixturing is paramount. I used them as parallels under my milling vise to elevate my workpiece, ensuring clearance for cutting tools and providing a stable, parallel base. This involved setting up and removing workpieces multiple times throughout a week, exposing the parallels to the usual workshop dust and occasional light mist of cutting fluid.

The initial setup was straightforward; their consistent thickness made it easy to achieve a level vise bed without extensive trial and error. There were no immediate surprises or quirks, just a smooth integration into my existing workflow. Their slim profile was a significant advantage in accommodating taller workpieces that might have otherwise interfered with the machine’s components.

Extended Use & Reliability

After several weeks of consistent use, the parallels have held up remarkably well. They continue to provide a flat and true surface, crucial for maintaining accuracy in my milling projects. Despite being subjected to the typical wear and tear of a busy workshop environment, including the occasional bump against a tool or workpiece, there are no noticeable cracks, significant scuffs, or performance drops.

Maintenance has been minimal; a quick wipe-down with a soft cloth after use is usually sufficient. I store them in their included protective case, which keeps them organized and prevents them from getting scratched or damaged. Compared to some budget parallels I’ve used in the past, which tended to dent or lose their flatness relatively quickly, this set from Grizzly Industrial has demonstrated superior durability and longevity.

Breaking Down the Features of Grizzly Industrial Thin Parallel Set

Specifications

The Grizzly Industrial Thin Parallel Set features ten pairs of parallels, each measuring a consistent 6 inches long. Their defining characteristic is their 1/8″ thickness, a critical dimension for creating precise setups in milling and machining operations. The set offers a range of widths, starting from 1/2″ and incrementing by 1/8″ all the way up to 1-5/8″.

These specifications are vital for versatility. The consistent length ensures predictable contact points, while the graduated widths allow for fine adjustments when setting up workpieces or fixtures. This variety means you can achieve a wide spectrum of heights and spacing, catering to numerous machining needs without needing an overwhelming number of individual parallels. The hardened and ground steel construction promises longevity and resistance to deformation under pressure.

Performance & Functionality

In practice, the Grizzly Industrial Thin Parallel Set performs its primary function exceptionally well, providing a stable and parallel foundation for my work. Their hardened and ground surfaces ensure that they don’t mar easily and maintain their flatness over time, which translates directly into more accurate machining results. The consistency across all pairs is a significant strength, eliminating the guesswork often associated with less precise fixturing tools.

A minor weakness, if one could call it that, is their relatively thin profile. While this is their primary advantage for accommodating taller workpieces, it also means they are more susceptible to damage from overtightening a vise or dropping them with significant force. However, within their intended use, their performance is robust and reliable, meeting and often exceeding expectations for a set in this price range.

Design & Ergonomics

The design of these parallels is straightforward and purposeful. They are made from hardened and ground steel, which gives them a satisfying heft and perceived sturdiness. The finish is smooth and precise, free from burrs or imperfections, and they feel solid and well-made in the hand.

Ergonomically, they are simple blocks of steel – their function is their form. Their slimness is their key ergonomic advantage in practical use, allowing for easy placement and manipulation under workpieces. There’s no real learning curve; their design is intuitive for anyone familiar with workshop practices. The consistent dimensions make them predictable and easy to work with, minimizing frustration during setup.

Durability & Maintenance

Given their hardened and ground steel construction, the Grizzly Industrial Thin Parallel Set is designed for longevity under typical workshop conditions. I anticipate these parallels lasting for many years of regular use, provided they are handled with a reasonable degree of care. Their robust build suggests they can withstand moderate clamping forces without deforming.

Maintenance is refreshingly simple. A quick wipe with a clean rag to remove dust or cutting fluid after each use is generally all that’s required. Storing them in their included case is essential to protect the precise ground surfaces from damage and prevent them from getting lost. There are no obvious failure points, though extreme impacts or bending forces could obviously cause damage due to their relatively thin profile.

Accessories and Customization Options

The Grizzly Industrial Thin Parallel Set comes with its own protective case, which is a crucial accessory for maintaining the integrity and organization of the set. This case features individual slots for each pair, preventing them from sliding around and potentially scratching or damaging each other.

Beyond the case, there are no specific customization options inherent to the parallels themselves. Their value lies in their precision and variety of sizes as supplied. However, their standard dimensions mean they integrate seamlessly with other common workshop accessories like vises, clamps, and milling machines.
