Why We Use PCD Diamond Tooling at TrueCore

At TrueCore MDF Doors, we’re obsessed with quality and that obsession doesn’t stop at materials. It extends to every step of our production process, including the cutting tools we use on our CNC. That’s why we’ve invested in PCD (Polycrystalline Diamond) tooling for all of our door profiles.

Sure, you can cut MDF with cheaper carbide bits. And for some, that’s enough. But if you’ve ever run your hand across a door fresh off the machine, you know there’s a difference between “cut” and clean. With PCD tooling, that difference is night and day.

Why PCD Tooling Beats Carbide Every Time?

1. Finish Quality That Speaks for Itself

We’ve run both carbide and PCD extensively. Carbide bits get the job done—but the surface is always just a little rough. It takes extra sanding, and the detail edges often don’t come out as crisp. PCD, on the other hand, produces a silky-smooth finish right off the machine. Less sanding. Less post-processing. Better quality, instantly.

2. Extended Tool Life

PCD tooling isn’t cheap and for good reason. These diamond-tipped bits last 10 to 15 times longer than traditional carbide bits. For a shop like ours, where we're cutting MDF day in and day out, that durability matters. It keeps our quality consistent, our machine time efficient, and our production flowing without constant tool swaps.

3. Precision That Stays Sharp

Carbide wears down fast, especially on dense MDF and HDF. The edge degrades, and suddenly your profiles look fuzzy, and your machine needs tweaking. PCD stays sharp for the long haul, which means your door details stay crisp, your edges stay clean, and your standards stay high.

4. A Smart Long-Term Investment

Yes, PCD bits are expensive. But if you're serious about MDF door production especially at scale it’s not a cost. It’s an investment. One that pays off in smoother finishes, less rework, and fewer bit changes. Over time, the durability and speed make up for the initial price tag and then some.

At TrueCore, quality isn’t an option it’s our standard. That’s why we run high-end diamond tooling across all of our door styles. When you order from us, you're not just getting a well-designed product you’re getting precision cuts, buttery-smooth edges, and doors that are ready to impress before they even hit the finish room.

Because in this business, the little details make the biggest difference.
