Review DMT Inch Dia sharp Mdiamond Bench Stone Extra coarse Handheld Sharpener
The **DMT 711181277890 Dia-Sharp MDiamond Bench Stone Extra-Coarse Handheld Sharpener** is a premium, high-performance sharpening tool designed for both professional craftsmen and dedicated DIY enthusiasts who demand precision, durability, and efficiency in their metalworking, woodworking, or general sharpening tasks. Engineered with DMT s signature innovation, this handheld diamond bench stone combines an aggressive extra-coarse grit (100-grit) with a robust, diamond-infused abrasive surface that delivers rapid material removal and exceptional edge restoration, making it ideal for resharpening dull chisels, gouges, knives, drills, and other cutting tools with ease. The compact yet sturdy design features a **low-profile, ergonomic handle** that ensures a secure, fatigue-free grip, allowing users to apply consistent pressure while maintaining control during sharpening. Unlike traditional whetstones or coarse stones that require constant lubrication and frequent flattening, this diamond-impregnated stone maintains its flatness and sharpness for extended periods, reducing downtime and maximizing productivity. Its **durable aluminum oxide base** provides stability on the workbench, while the **self-sharpening diamond particles** embedded in the abrasive matrix ensure a consistently smooth, even finish without the need for frequent resurfacing. Whether tackling stubborn, heavily worn tools or restoring edges on high-carbon steel blades, this bench stone excels in both speed and accuracy, making it a versatile addition to any workshop. Built to last, the Dia-Sharp MDiamond series is resistant to clogging, waterproof, and capable of handling a wide range of materials, from soft metals like aluminum to tougher alloys such as stainless steel. For those who prioritize performance without compromise, this extra-coarse diamond bench stone is an indispensable tool for achieving professional-grade results with minimal effort.
### **Pros and Cons of buying a DMT 711181277890 Dia-Sharp MDiamond Bench Stone (Extra-Coarse, Handheld Sharpener)**
#### **Pros**
1. **High Durability and Longevity** Made with diamond-infused abrasive material, this sharpener is designed to last significantly longer than traditional ceramic or aluminum oxide stones. The diamond particles remain effective for extended use, even on tough materials like carbide-tipped tools.
2. **Versatility** Suitable for sharpening a wide range of cutting tools, including:- Carbide-tipped tools (e.g., chisels, gouges, planer irons)
- High-speed steel (HSS) bits
- Drills and reamers
- Some types of knives and scissors (though finer grits are better for delicate edges)
- The extra-coarse grit (typically around 300 400) makes it ideal for restoring dull or damaged blades quickly.
3. **Handheld Convenience** Unlike fixed bench stones, this handheld model allows for portability and ease of use in workshops or job sites. It can be held in one hand while the other operates the tool, improving efficiency.
4. **Effective for Heavy-Duty Work** The coarse grit is designed to remove material quickly, making it useful for:- Restoring severely worn tools
- Shaping and refining edges before moving to finer grits
- Handling tools with stubborn or uneven wear patterns
5. **Compatibility with Lubrication** While not strictly required, using a lubricant (like water, oil, or diamond sharpening fluid) enhances performance by reducing heat and debris buildup, extending the stone s life.
6. **Budget-Friendly for Diamond Stones** Diamond stones are generally more expensive than ceramic or aluminum oxide stones, but this model offers a cost-effective option for serious woodworkers, metalworkers, or DIY enthusiasts who need reliable sharpening.

#### **Cons**
1. **Limited for Fine Edge Work** The extra-coarse grit is not suitable for achieving razor-sharp edges on delicate tools (e.g., pocket knives, high-end kitchen knives, or precision saws). Users will need additional finer grit stones (e.g., 1000 grit) for final honing.
2. **Requires Proper Technique** Unlike automatic sharpeners, this stone demands skill to use effectively. Incorrect angles or pressure can lead to uneven sharpening or damage to the tool. Beginners may struggle with consistency.
3. **Dust and Debris Production** Diamond stones generate fine abrasive dust when sharpening carbide or hard materials. This can be messy and may require proper ventilation or a dust extraction system to avoid inhalation or clogging.
4. **Not Ideal for Soft Metals** While it works well on hard materials like carbide and HSS, it may not be efficient for softer metals (e.g., mild steel) where finer grits are more appropriate. Overuse on soft metals could wear down the stone prematurely.
5. **Maintenance Needed** The stone must be periodically cleaned of embedded debris (using a brush or water) to maintain its effectiveness. Neglecting maintenance can reduce its lifespan.
6. **Size and Portability Trade-Off** While handheld, the stone is not as compact as some smaller sharpeners. It may be bulkier than pocket-sized tools, limiting its use in tight spaces.
7. **Cost of Replacement** Diamond stones are more expensive to replace than traditional stones, so users should ensure they will get sufficient use out of it before purchasing.

### **Conclusion**
The **DMT Dia-Sharp MDiamond Bench Stone (Extra-Coarse)** is a robust, high-performance sharpening tool best suited for **heavy-duty, high-wear applications**, particularly with carbide-tipped tools, HSS bits, and other tough materials. Its diamond abrasive ensures durability and efficiency for removing material quickly, making it a valuable addition to workshops focused on woodworking, metalworking, or general tool maintenance.
However, it is **not a standalone solution** for achieving ultra-fine edges. Users will need to pair it with finer grit stones (e.g., 1000 grit) for final honing. Additionally, its coarse nature means it s better for restoration and rough shaping rather than precision work.
For **serious hobbyists, professionals, or DIYers** who frequently work with hard materials and prioritize longevity and performance, this stone is a worthwhile investment. For **casual users or those needing fine-edge sharpening**, a more versatile setup (e.g., a combination of coarse and fine stones) may be preferable.
---
### **Recommendation**
**Buy this stone if:**- You frequently sharpen **carbide-tipped tools, HSS bits, or other hard materials**.
- You need a **durable, long-lasting** sharpening solution that can handle heavy wear.
- You already own or plan to purchase **finer grit stones** for final honing.
- You value **portability and ease of use** in a handheld format.
**Avoid or reconsider if:**- You primarily work with **soft metals or delicate tools** (e.g., knives, scissors) that require fine edges.
- You are a beginner and lack experience with manual sharpening techniques.
- You do not have access to **proper ventilation or dust control** for diamond stone use.
- You are on a tight budget and cannot afford to replace it if it wears out quickly due to improper use.
**Best Use Case:**Pair this stone with a **waterstone or oilstone (1000 grit)** for a complete sharpening system. Use it for **initial restoration and coarse grinding**, then move to finer stones for polishing. For optimal results, invest in a **sharpening guide or angle gauge** to maintain consistent bevels.
