Glass Tools Diamond Drill Bits, Chamfering Sleeves and Milling Wheels

Today we introduce a group of commonly used abrasive products in the glass industry, diamond drill bits, chamfering sleeves, and diamond milling wheels. Diamond drill bits are mainly used for glass drilling and gem coring; chamfering sleeves are mainly used in conjunction with diamond drill bits to process the edges of holes; diamond milling wheels are mainly used for grinding optical glass. Let's take a detailed look at the characteristics and functions of each product.

Diamond Drill Bit

Definition and composition

The diamond drill bit is a tool specially used for glass drilling and coring, which is characterized by high efficiency and high precision. It consists of a steel matrix and a diamond abrasive layer, which has excellent wear resistance and cutting ability. This combination is able to form high-quality holes and cores on glass materials.

Design features

• Abrasive layer: The diamond abrasive layer is typically made of high-quality diamond particles that are carefully selected and bonded to ensure optimal cutting performance and durability. The standard thickness of this layer is approximately 1 mm, while the overall height of the drill bit is approximately 10 mm. This thin-walled design helps to easily penetrate glass, minimize wear, and extend the life of the tool.

• Shank variations: Diamond drill bits come in a variety of shank designs, including:

• Straight shank: Typically used for standard applications.

• Tapered handle: provides better grip and stability.

• Threaded shank: allows secure attachment to drilling equipment.

These shank designs enhance the versatility of diamond drill bits, making them suitable for a wide range of applications in glass processing and laboratory environments.

Application and usage

• Importance of outside and inside diameters: When selecting a diamond drill bit for glass drilling, the outside diameter is critical to ensure the hole is the correct size and has a smooth surface. For coring applications, the inside diameter is even more important as it determines the size of the core material to be extracted. In areas such as gemstone processing, where precise measurements are essential, the accuracy of the inside diameter is particularly important.

• Coolant use: To achieve high-quality results and maintain the integrity of the drill bit and the glass material, it is recommended to use a suitable coolant during the drilling and coring process. The coolant helps to dissipate heat, reducing the risk of glass damage and ensuring smoother operation.

Diamond Chamfer Sleeve

Definition and purpose

The diamond chamfering sleeve is a special tool used with a diamond drill bit. Its main function is to make the edge of the glass after drilling smoother. By using the chamfering sleeve, users can improve the quality and aesthetics of the finished glass.

Design features

• Easy to install: The chamfered sleeve is designed to be easily installed on diamond drill bits, allowing for effective treatment of glass hole edges immediately after drilling.

• Smoothness and precision: The chamfered sleeve ensures the edges of the glass hole are smooth and precise, which is critical for both functional and aesthetic considerations.

Diamond Chamfering Grinding Head

Function

In addition to the chamfering sleeve, a diamond chamfering head is also available. This tool is specially designed for machining the inner edge of glass holes.

Design features

• Flexible handle: The grinding head is equipped with a flexible handle, which allows multiple operation methods, including handheld use or connected to a machine. This versatility makes it suitable for different working environments and user preferences.

• High quality abrasive: The grinding head is made of high-quality diamond abrasive, which can effectively remove burrs and sharp edges inside the glass hole and enhance the smoothness of the hole.

Usage tips

Coolant use

When using diamond chamfering sleeves or grinding points, it is recommended to use a suitable coolant. This helps:

• Reduce tool temperature during operation.

• Ensure smooth and efficient processing.

Diamond Grinding Wheel

Definition and purpose

A diamond grinding wheel is a diamond tool specifically designed for grinding optical glass. It looks similar to a diamond drill bit, but has a thicker abrasive layer, making it particularly effective in this application.

Design features

• Abrasive layer: Diamond milling cutters are equipped with a high-quality abrasive layer consisting of carefully selected diamond particles. This ensures excellent cutting performance and durability, which is essential for achieving high-quality results in optical glass processing.

• High hardness steel matrix: Grinding wheels are typically constructed with a high hardness steel matrix, providing the necessary strength and durability to withstand the demands of grinding operations.

• Handle design: The shank of the diamond milling cutter is specially designed to match the specifications of the internal thread shank. This design facilitates easy installation and disassembly, thereby improving processing efficiency and reducing operating difficulty.

Usage tips

Coolant use

When using diamond grinding wheels for optical glass grinding, it is highly recommended to use a suitable coolant. The coolant has several important functions:

• Temperature control: It helps to reduce the temperature of the milling wheel during operation, preventing overheating and potential damage to the tool and glass.

• Smoother machining: Using coolant ensures a smoother grinding operation, resulting in a better surface finish and improved overall quality.
