When drilling glass, cutting holes in ceramic tiles, or engraving detailed patterns into stone, choosing the right diamond tool is essential for achieving precise results and reducing material damage.
Electroplated diamond drill bits, diamond hole saws, and diamond grinding burrs are widely used for processing hard and brittle materials such as glass, marble, ceramic, and selected natural stones.
Unlike conventional cutting tools, electroplated diamond tools use diamond abrasive particles secured to a metal body through a nickel electroplating process. This creates an exposed abrasive surface suitable for controlled drilling, grinding, carving, and detail finishing.
In Electroplated Diamond Tools Buying Guide Part 1, we introduced electroplated diamond saw blades, grinding wheels, and stone profile wheels.
In Part 2, we focus on two additional product categories:
- Electroplated Diamond Drill Bits and Hole Saws for drilling glass, ceramic tiles, marble, and other compatible materials.
- Electroplated Diamond Burrs and Grinding Bits for stone carving, glass engraving, edge finishing, and precision grinding.
This guide explains their applications, available specifications, diamond grit options, and how to choose suitable tools for professional use.
1. What Are Electroplated Diamond Drill Bits and Burrs?
Electroplated diamond drill bits and burrs are abrasive tools manufactured by attaching diamond particles to a metal base using an electroplated nickel bonding layer.
The diamond particles form the working surface that removes material through abrasion.
Most conventional electroplated diamond tools have a single layer of diamond abrasive particles.
This design offers several advantages:
- High diamond grain exposure for efficient material removal.
- Precise abrasive action for detailed drilling and grinding.
- Flexible manufacturing of different shapes and sizes.
- Compatibility with many specialized glass, stone, and ceramic processing applications.
However, because standard electroplated tools generally contain only one abrasive layer, their working performance gradually decreases as the diamond particles wear or detach.
For this reason, electroplated diamond tools should be selected according to the workpiece material, operating conditions, and required processing quality.
2. Main Types of Electroplated Diamond Drilling and Grinding Tools
Electroplated diamond drilling and grinding tools are available in different configurations.
The two main categories discussed in this guide are diamond drill bits and hole saws, and diamond grinding bits and burrs.
2.1 Electroplated Diamond Drill Bits and Hole Saws
Electroplated diamond drill bits are designed for creating holes in suitable hard and brittle materials.
Many electroplated drilling tools use a hollow cylindrical cutting head, commonly known as a diamond hole saw.
Instead of removing the entire hole area like a conventional twist drill, a diamond hole saw grinds through the material around the circumference of the hole.
This structure can reduce the amount of material that needs to be removed when drilling larger openings.
Electroplated diamond hole saws are commonly used for:
- Drilling glass panels and glass products.
- Making holes in ceramic tiles.
- Drilling marble and decorative stone.
- Processing certain ceramic products.
- Creating openings in other compatible brittle materials.

For OEM buyers, custom diamond burr shapes can be reviewed according to technical drawings or samples.
3. Applications of Electroplated Diamond Drill Bits
Different drilling materials require different cutting conditions.
An electroplated diamond hole saw suitable for glass may not provide the same performance when drilling dense porcelain or highly abrasive stone.
Understanding the material is therefore one of the most important steps in selecting the right diamond drill bit.
3.1 Diamond Hole Saws for Glass Drilling
Glass is hard and brittle, making it vulnerable to cracking or chipping when excessive pressure is applied.
A properly selected diamond hole saw for glass removes material through grinding rather than conventional sharp-edge cutting.
This makes diamond abrasive drilling suitable for many glass processing applications.
Typical uses include:
- Drilling glass panels.
- Creating holes in glass bottles and decorative products.
- Glass craft processing.
- Manufacturing glass components with drilled openings.
Tips for Drilling Glass with Diamond Hole Saws
For suitable glass materials and approved drilling tools:
- Secure the glass firmly on a stable support.
- Select the correct diamond hole saw diameter.
- Use the recommended drilling speed.
- Apply water cooling when required by the tool and machine.
- Maintain controlled pressure and avoid excessive force.
- Reduce feed pressure as the drill approaches the exit surface.
For better hole quality, proper workpiece support is particularly important.
Important: Ordinary glass drilling techniques must not be assumed suitable for tempered or safety glass. Many types of tempered glass cannot be drilled after tempering without shattering.
3.2 Diamond Drill Bits for Ceramic Tile and Porcelain
Ceramic tiles are widely used in bathrooms, kitchens, and construction projects.
Drilling holes in tile requires suitable tools because the hard glazed surface and brittle body can make conventional drilling difficult.
Electroplated diamond drill bits for ceramic tile can be useful for drilling compatible ceramic materials under appropriate conditions.
Common applications include:
- Bathroom tile installation.
- Kitchen wall tile drilling.
- Drilling holes for plumbing fixtures.
- Decorative tile processing.
- Ceramic product manufacturing.
Ceramic Tile vs Porcelain Tile
Not all tiles have the same characteristics.
Glazed Ceramic Tile
Glazed ceramic tiles generally have a ceramic body with a decorative or protective glazed surface.
Depending on their hardness and structure, some can be drilled using suitable electroplated diamond hole saws.
Porcelain Tile
Porcelain tiles typically have a dense, low-absorption body and can be more demanding to drill.
For hard porcelain tile, vacuum brazed or other specialized diamond drilling tools may offer better performance, depending on the application.
Therefore, buyers should not assume that every electroplated diamond hole saw is suitable for continuous drilling of dense porcelain.
Before placing bulk orders, professional users should test the selected tool on the actual tile material.
3.3 Diamond Hole Saws for Marble and Natural Stone
Marble is widely used for countertops, wall decoration, architectural elements, and interior stone products.
A suitable diamond hole saw for marble can be used to create openings for fittings, decorative components, and other installations.
Applications may include:
- Marble slab drilling.
- Stone countertop fabrication.
- Decorative stone product manufacturing.
- Drilling holes in natural stone accessories.
- Customized stone processing.
When drilling marble, users should consider material thickness, internal cracks, machine stability, and cooling requirements.
For granite and other harder natural stones, the tool design and bonding method should be selected according to the stone’s abrasiveness and the required production volume.
4. Applications of Electroplated Diamond Burrs and Grinding Bits
While diamond hole saws are primarily used for drilling, electroplated diamond grinding bits are designed for detailed grinding, engraving, shaping, and localized material removal.
They are especially useful when larger grinding wheels cannot reach narrow or complicated areas.
4.1 Diamond Burrs for Stone Carving
Diamond carving burrs for stone are used to shape small details and decorative features on suitable natural and engineered stone materials.
Typical applications include:
- Marble carving.
- Decorative stone engraving.
- Stone sculpture detail work.
- Small groove grinding.
- Edge correction and shape adjustment.
Different burr shapes are selected according to the required carving geometry.
For example, a pointed burr can be suitable for narrow details, while a cylindrical burr may be more appropriate for processing straight areas or grooves.
Stone hardness and abrasiveness can significantly affect burr performance and service life.
4.2 Diamond Grinding Bits for Glass Engraving
Glass engraving requires accurate control because the material is brittle and can be damaged by excessive pressure or vibration.
Diamond burrs for glass engraving can be used to create decorative patterns, shallow grooves, and localized surface textures.
Applications include:
- Decorative glass engraving.
- Glass craft production.
- Small detail grinding.
- Surface texture processing.
- Edge and corner correction.
Finer diamond grit sizes may be selected when a more controlled surface finish is required.
However, the final appearance also depends on the burr shape, operating speed, contact pressure, and engraving technique.
4.3 Diamond Burrs for Ceramic Grinding and Edge Finishing
Ceramic products may require localized grinding after forming, cutting, or drilling.
Small diamond burrs can be useful for reaching narrow areas and processing detailed edges.
Typical tasks include:
- Ceramic edge correction.
- Small hole enlargement.
- Localized chamfering.
- Grinding curved sections.
- Removing minor surface irregularities.
For particularly hard technical ceramics or highly dense porcelain, a specialized diamond tool may be required.
5. How to Choose the Right Electroplated Diamond Drill Bits and Burrs
Choosing the correct electroplated diamond tool depends on the material, processing method, required accuracy, and machine configuration.
5.1 Choose the Right Tool for Your Material
Different workpiece materials require different tool characteristics.

This table provides general selection guidance rather than a guarantee of suitability for every material.
Professional buyers should confirm the actual tool design and conduct sample testing when necessary.
5.2 Select the Correct Diameter and Shank Type
For electroplated diamond drill bits, diameter determines the size of the hole.
The available product range discussed in this guide covers common diameters from 5 mm to 170 mm.
For diamond grinding burrs, the working diameter affects accessibility and the amount of material removed.
Common working diameters include:
- 6 mm.
- 8 mm.
- 10 mm.
- 12 mm.
Common shank diameters include 3 mm and 6 mm.
Before purchasing, verify that the tool shank or thread matches the intended machine.
The tool’s maximum rated RPM must also be compatible with the equipment.
5.3 Understanding Diamond Grit Size: 60, 80, 100 and 150 Mesh
Diamond grit size plays an important role in grinding performance and surface quality.
In general, lower mesh numbers indicate coarser abrasive particles, while higher mesh numbers indicate finer particles.
Common electroplated diamond burr grit options include:
| Diamond Grit | Relative Grade | Typical Application |
|---|---|---|
| 60 Mesh | Coarse | Aggressive grinding and initial shaping |
| 80 Mesh | Medium-Coarse | General material removal |
| 100 Mesh | Medium | Controlled grinding and detail work |
| 150 Mesh | Fine | Finer grinding and surface preparation |
These applications are general guidelines. The actual abrasive grading system and results should be confirmed according to the specific product.
Coarse vs Fine Diamond Burrs
Coarse Diamond Burrs
Coarse diamond burrs are typically selected when faster material removal is more important than obtaining a fine surface.
Fine Diamond Burrs
Finer diamond grinding bits can be useful for controlled detail processing and improving the intermediate surface finish.
For certain precision applications, several grit stages may be required.
A 150-mesh diamond burr should not be considered a substitute for final polishing when a high-gloss finish is required.
5.4 Choose the Right Diamond Burr Shape
The working shape directly affects how the diamond burr contacts the material.
For example:
- Cylindrical burrs can be selected for flat areas and straight-sided surfaces.
- Ball burrs can be selected for rounded details and concave areas.
- Conical burrs can be used for tapered surfaces and narrow grooves.
- Pointed burrs can be selected for fine engraving and intricate patterns.
The shape should be chosen according to the workpiece geometry rather than simply selecting the largest or most aggressive burr.
6. Electroplated vs Vacuum Brazed Diamond Drill Bits: What’s the Difference?
Electroplated and vacuum brazed diamond drill bits both use diamond abrasives attached to a metal tool body.
However, their bonding technologies are different.
Electroplated diamond drill bits generally use nickel electroplating to secure diamond particles.
Vacuum brazed diamond drill bits use a brazing alloy to create a metallurgical bond between the abrasive particles and the tool body.
These differences can influence diamond retention, cutting behavior, and tool design.
| Feature | Electroplated Diamond Drill Bits | Vacuum Brazed Diamond Drill Bits |
|---|---|---|
| Bonding Technology | Nickel Electroplating | Vacuum Brazing |
| Diamond Structure | Usually Single Layer | Usually Single Layer |
| Abrasive Exposure | High | High |
| Typical Advantage | Controlled Abrasive Drilling | Strong Diamond Attachment |
| Suitable Materials | Selected Glass, Ceramic, Stone | Selected Tile, Stone and Other Compatible Materials |
| Tool Life | Depends on Application | Depends on Application |
| Main Selection Factors | Material, Finish, Speed, Cooling | Material, Cutting Performance, Cooling |
For example, an electroplated diamond hole saw may be appropriate for certain glass drilling applications.
For demanding porcelain tile drilling, a properly designed vacuum brazed diamond hole saw may offer advantages.
However, neither bonding method guarantees superior performance in every application.
The best choice depends on the diamond specification, tool construction, machine, workpiece, and operating conditions.
7. Tips for Better Drilling and Grinding Performance
Correct operation is essential for achieving consistent performance from electroplated diamond drill bits and grinding burrs.
