Adam Savage's One Day Builds - Annular Cutter Storage!
**The Art of Tool Storage: Creating a Custom Holder for Annular Cutters**
Hey there! It’s later than I usually shoot a video—it’s 5:30. I’m starting this video right now because I just got back from my summer vacation. Just to give you a quick update, I’m currently a bachelor since my wife is still enjoying her vacay. Anyway, here we go.
So, as per the title of this video, I have something special here—a piece of wood that’s going to be my storage solution for annular cutters. Now, what exactly are annular cutters? Well, I’m so glad you asked! I’ve covered them in recent videos on my channel, but before diving into annular cutters, let me first talk about drill bits because that sets the foundation.
Imagine you’re a maker, and you think to yourself, “Maker, I want to make a hole of a certain size.” That’s a funny thing to say to yourself, right? But let’s say you want to make a 1.5-inch diameter hole in some deep material. You have several options, especially if you’re a beginning maker with access to affordable tools.
Most beginners start with a hole saw—plumbers use them all the time. There are abrasive ones and toothed ones, and it’s a good idea to set yourself up with a complete system of hole saws. I’ve got an entire drawer full of them; they’re incredibly useful. For instance, you can cut sideways into steel pipe to make roll cages for your car. These things are like the bottom rung of a ladder because they’re affordable and everywhere—you’ll find them at every hardware store.
Now, about the pilot drill here—it’s not sticking out far enough, but that’s okay. Unlike a regular drill bit, which excavates material by rotating and cutting through it, a hole saw only cuts around the perimeter. Instead of dealing with the entire area (pi r squared), you’re working within the width of the saw, which is typically about 60 thou or half a millimeter.
But let me introduce you to another tool that’s a game-changer: the Forstner bit. These bits are like something out of science fiction—they’re not even in the main aisle at Sears, yet they’re amazing. A full set can be had for around $30, though you could spend up to $100 if you want premium ones. I prefer the cheaper sets because I’m hard on tools and cycle through them regularly.
The Forstner bit is designed to cut through solid stock and create clean, beautiful holes. It has chisels that balance against a central point, making it excellent for precision work. However, it’s still labor-intensive because it does a lot of material removal.
Now, let’s talk about annular cutters—courtesy of John Knoll from Lucasfilm and Mandalorian fame (though he’s been doing this for decades). These cutters operate much like hole saws but are far more refined. Each leading edge is precision-engineered, resulting in a superior surface finish—one that’s every bit as good as what you’d get from a Forstner bit.
I’ll admit it: I can be a bit excessive with my tool collection. When I got excited about annular cutters, I bought a set containing six or seven of them. They were incredibly useful, but then I kept running into situations where I needed different sizes. So, I looked it up—annular cutters are available in every size from 7/16 inches all the way up to 2 inches by the inch. That’s pretty amazing when you get to the larger sizes; they can cost around $50 each.
But here’s where things got interesting: I decided to buy them all. I figured, “Why not? I’ll always need these.” So, I invested in a set—though I’m not exactly sure of the exact number now, let’s say 29 of them—and I’m about to set this up in my mill to create a custom holder for all of them.
The idea is simple: gang them up like this and have them sit in pockets they’ve made themselves. This setup keeps their edges protected and prevents dust buildup. It’s a brilliant way to store them. I can already see that it’ll hold 26 of my bits perfectly, even if the three larger ones are a bit more challenging to fit in.
To be honest, I thought I was showing you the drilling process with the annular cutters earlier, but I ended up doing most of it off-camera. Apologies for the confusion! But what I can show you now is the result: solid holding and beautiful precision. It’s the kind of satisfaction that comes from a well-executed build.
As I sit here on my stool, putting my tools away, I realize this is exactly why I love machining—everything fits together perfectly, and there’s nothing quite as satisfying as seeing a tool slide into its custom-made pocket. This holder is like the most beautiful drill set hole saw ever, even if it does cost a fortune.
But hey, what can I say? It’s worth every penny to me. These annular cutters are truly remarkable tools, and I’m thrilled with how this storage solution turned out. Even though I have three extra ones that need their own little holder, the rest fit perfectly in this custom setup.
I could talk about this all day, but I think it’s time to wrap things up. It’s been too long since I’ve been on camera, and I’m just getting my bearings back. Thanks for joining me—next time, we’ll dive into another exciting project!
