Let’s Talk About Grizzly Industrial Insert Type Blade
The Grizzly Industrial Insert Type Blade is a seemingly simple, yet crucial component for any serious machinist using a lathe. Made by Grizzly Industrial, this parting blade is designed to work with their T10382 Parting Blade Holder and uses readily available GTN3 wedge type inserts. What sets it apart is its promise of precision and efficiency in parting operations, something any experienced machinist knows can be a delicate and time-consuming process.
I’ve spent years wrestling with traditional high-speed steel (HSS) parting tools. I needed a system that offered faster cutting speeds, better surface finishes, and reduced chatter – something that HSS tools often struggle with, especially on harder materials.
My initial unboxing experience was straightforward; the blade arrives as a single, solid piece of steel. The finish is clean and the dimensions, 26 mm L x 110mm W x 3.1mm T, appear accurate, lending an immediate impression of quality and precision.
Compared to solid HSS parting blades, this insert type blade offers a huge advantage; you can easily replace worn or damaged cutting edges without having to regrind the entire tool. I considered a few other insert parting blade options, including some from Sandvik and Kennametal, but the Grizzly Industrial option seemed like a good balance of price and performance. I decided to go with Grizzly Industrial because I had previously had a pleasant experience with the Grizzly Industrial lathe.
My first impression was one of cautious optimism. While the blade itself looks well-made, the real test would be in its performance.
Real-World Testing: Putting Grizzly Industrial Insert Type Blade to the Test
First Use Experience
I first tested the Grizzly Industrial Insert Type Blade on a project involving parting off some 1.5-inch diameter 4140 steel on my lathe. I used a moderate spindle speed and feed rate, ensuring proper lubrication to avoid overheating. I was working in a shop environment, so weather was not a concern for this blade.
Right off the bat, I noticed a significant reduction in chatter compared to my HSS parting tools. The blade cut cleanly and efficiently through the steel, producing a surprisingly smooth surface finish.
My initial concern was that without the proper setup the blade would not work, or cause harm. To my surprise and relief, the setup was very easy and the tool worked exactly as it was designed to.
Extended Use & Reliability
After several weeks of using the Grizzly Industrial Insert Type Blade on various materials, including aluminum, brass, and stainless steel, I can confidently say it has held up exceptionally well. I would estimate I have used it for around 40 hours of machine time. There is no sign of any degradation in performance at this point.
The blade itself shows no signs of wear and tear, and the replaceable inserts make maintenance a breeze. I simply swap out the worn insert for a new one and I am back in business.
Compared to my previous experience with HSS parting tools, the Grizzly Industrial Insert Type Blade is a game-changer. It offers superior performance, increased efficiency, and reduced downtime due to sharpening and tool changes. I would absolutely recommend this to anyone in a similar machine shop situation.
