The DMT Dia-Flat Diamond Lapping Plate is designed to tackle a variety of sharpening stones, including oil stones. It features DMT’s Hardcoat Technology, providing a durable diamond surface that the manufacturer claims outperforms other available coatings. This makes the plate a handy tool for flattening stones with relatively little effort.
However, the plate's performance can vary based on the type and hardness of the stone you're dealing with. From our research, it generally works well, but there might be some challenges with very hard stones, like older oil stones that are around 38 years old. In cases like these, you might need to look into other flattening methods.
On the brighter side, the plate shines with standard water stones and softer materials.
The plate's grit is quite aggressive at 95 microns / 160 mesh, which is effective for flattening. Though, keep in mind, this might be too much for stones requiring a finer finish. Some have found this grit level helpful, especially for demanding stones, achieving the flatness they were aiming for.
When it comes to flatness and durability, the feedback varies. Many users appreciate its precise flatness, certified to within +/- 0.0005 inches, and its durability after years of use. Yet, some express concerns about the diamond surface wearing down unevenly over time.
So, results can really depend on how you use the plate, including the pressure you apply and the types of stones you work with.
In short, the DMT Dia-Flat is generally reliable for a range of stones, but it's important to consider your stones' specific hardness and needs for the best outcome and longevity of the plate.
When it comes to how long the DMT Dia-Flat Diamond Lapping Plate lasts, it really depends on a few factors like its design and quality. The manufacturer uses something they call Hardcoat Technology, which is meant to make the diamond surface more durable than other diamond sharpeners out there. They also claim it has a precision-ground flatness, which is important for keeping your sharpening stones and waterstones in good shape.
Based on our research, folks who've used it are pretty happy with how long it lasts. Some say it's great at flattening waterstones and works really efficiently. There's even a review mentioning that after ten years, it's still as solid as when it was first bought—that's a pretty good sign of its longevity if used properly.
On the flip side, a few people have had issues with the diamonds not being evenly spread across the surface, and some have noticed them coming off early on. It seems like using light pressure, as the manufacturer suggests, could help with these issues.
So, while it might be a bit pricey, a lot of the feedback is positive about its long-term reliability and how well it works.
Of course, as with anything, people have different experiences, so it’s a good idea to think about if these might impact you before making a decision.
The DMT Dia-Flat Diamond Lapping Plate is pretty impressive when it comes to flattening sharpening stones—whether you’re dealing with conventional stones, waterstones, or oilstones. The manufacturer highlights its DMT Hardcoat Technology, which supposedly lasts longer than other diamond coatings. Plus, it's hand-certified to be flat within a super precise tolerance of +/- 0.0005 inches. This means you'll get a consistently flat surface on your sharpening stones.
Our research shows that people really like its aggressive diamond surface, which seems to flatten various types of stones quickly. It even works well on fine grit stones, like 10000 grit waterstones. It's got a solid rating of 4.5 out of 5 stars from 208 reviews, indicating that most folks are pretty happy with it.
On the flip side, you’ve got to be careful with it. Some folks have noticed that its diamond coating can wear down, especially if too much pressure is used. To avoid this, using gentler pressure can help preserve the plate and make it last longer. This tip is worth considering, especially given that the lapping plate isn’t cheap.
So, if precision is your thing and you're careful with your tools, the DMT Dia-Flat Diamond Lapping Plate could be a good investment. It's perfect for keeping your sharpening stones flat and ready to use. Just handle it with care to make the most of it.
