Tip #1: Choosing the Right Diamond Bit for the Job

Not all diamond bits are created equal. Selecting the right bit for the task is crucial for achieving optimal results and preventing damage to your tools.

Factors to Consider:

Grit Size:
- Coarse (60-120 grit): For removing significant amounts of material, reshaping damaged edges, or sharpening very dull tools.
- Medium (120-200 grit): For general sharpening and maintaining a sharp edge.
- Fine (400+ grit): For honing and polishing the edge to a razor-sharp finish.
Bit Shape:
- Cone-shaped: Ideal for sharpening curved edges, such as gouges or carving tools.
- Cylindrical: Suitable for sharpening straight edges, like chisels or plane blades.
- Disc-shaped: Useful for sharpening larger surfaces or creating a bevel.
- Ball-shaped: Great for detail work and reaching tight corners.
Diamond Coating:
- Single-layer: More aggressive cutting, but shorter lifespan.
- Multi-layer: Longer lifespan, but less aggressive cutting.
Shank Size: Ensure the shank size of the bit is compatible with your Dremel tool.

Actionable Steps:

Identify the Tool: Determine the type of tool you need to sharpen and the shape of its cutting edge.
Assess the Dullness: Evaluate how dull the tool is. If it’s very dull or damaged, start with a coarse grit. If it’s just a little dull, a medium grit will suffice.
Select the Bit: Choose the appropriate bit shape and grit size based on the tool and its condition.
Consider the Material: For very hard materials like carbide, always opt for a diamond bit specifically designed for carbide.
Test: Before committing to sharpening the entire tool, test the bit on a small, inconspicuous area to ensure it’s removing material effectively and not causing damage.

Example:

I was recently sharpening a set of masonry drill bits that had seen better days. The tips were worn down from drilling through concrete. I started with a coarse, cone-shaped diamond bit (80 grit) to reshape the tips. Then, I switched to a medium grit (150 grit) to refine the edge. Finally, I used a fine grit (400 grit) to polish the cutting surface for optimal performance.

Cost Considerations:

Diamond bits can range in price from a few dollars to upwards of $30 or more, depending on the grit, shape, and quality. Investing in a set of high-quality bits is generally more cost-effective in the long run, as they will last longer and provide better results.

Tip #2: Mastering the Sharpening Technique

Sharpening with a Dremel diamond bit requires a delicate touch and a steady hand. Here’s how to master the technique:

Step-by-Step Guide:

Secure the Tool: Firmly clamp the tool you are sharpening in a vise or use a specialized sharpening jig to ensure it doesn’t move during the process. Stability is key to achieving a consistent edge.
Set the Speed: Start with a low to medium speed on your Dremel. High speeds can generate excessive heat, which can damage the diamond bit and the tool. Experiment to find the optimal speed for your specific bit and material.
Apply Light Pressure: Let the diamond bit do the work. Applying too much pressure can cause the bit to overheat, wear down prematurely, or even break. Use light, controlled strokes.
Maintain a Consistent Angle: Hold the Dremel at the correct angle relative to the cutting edge. This angle will vary depending on the tool you are sharpening. Refer to the tool’s specifications or use a sharpening guide to determine the appropriate angle.
Move the Bit: Keep the bit moving across the cutting edge. Avoid dwelling in one spot for too long, as this can create flat spots or uneven sharpening.
Cooling: Periodically dip the diamond bit in water to cool it down. This helps prevent overheating and extends the life of the bit. You can also use a coolant specifically designed for sharpening.
Inspect the Edge: After each pass, carefully inspect the cutting edge to assess your progress. Use a magnifying glass if necessary.
Repeat: Continue sharpening until the cutting edge is sharp and free of any nicks or burrs.
Honing (Optional): For a razor-sharp finish, you can hone the edge with a fine-grit diamond bit or a leather strop.
