Mounted points are small grinding tools used for precision grinding, deburring, and finishing operations. They consist of abrasive grains bonded together and attached to a spindle or mandrel, allowing them to be mounted onto a rotary tool or grinder. These tools are essential in various industries, including metalworking, woodworking, and manufacturing, due to their versatility and ability to perform detailed work. In metalworking, mounted points are used for deburring sharp edges, smoothing weld seams, and finishing intricate parts. They are ideal for reaching tight spaces and corners that larger grinding tools cannot access. In woodworking, they help in shaping and smoothing wooden surfaces, especially in detailed carvings and intricate designs. Mounted points are also used in the automotive and aerospace industries for precision grinding of engine components, turbine blades, and other critical parts. They ensure that these components meet strict tolerances and surface finish requirements. In jewelry making and watchmaking, mounted points are employed for polishing and finishing delicate pieces, ensuring a high-quality finish without damaging the material. They are also used in dental laboratories for shaping and polishing dental prosthetics. The variety of shapes, sizes, and abrasive materials available for mounted points allows them to be tailored to specific applications, whether it involves removing material, refining surfaces, or achieving a particular finish. Common abrasive materials include aluminum oxide, silicon carbide, and diamond, each suited for different materials and tasks. Overall, mounted points are indispensable tools for achieving precision and quality in detailed grinding and finishing tasks across various industries.

To choose the right mounted point for a specific task, consider the following factors: 1. **Material of Workpiece**: Identify the material you are working on (e.g., metal, glass, plastic). Harder materials require mounted points made of tougher abrasives like aluminum oxide or silicon carbide. 2. **Shape and Size**: Select the shape (e.g., cylindrical, conical, ball) and size of the mounted point based on the contours and dimensions of the workpiece. Smaller points are suitable for precision work, while larger ones are for broader surfaces. 3. **Abrasive Type**: Choose the abrasive material based on the task. Aluminum oxide is versatile for general-purpose grinding, while silicon carbide is ideal for non-ferrous metals and softer materials. 4. **Grit Size**: Determine the grit size according to the finish required. Coarse grits (lower numbers) are for rapid material removal, while finer grits (higher numbers) provide a smoother finish. 5. **Bond Type**: Consider the bond type (e.g., vitrified, resin) that holds the abrasive grains. Vitrified bonds are durable and heat-resistant, suitable for heavy-duty tasks, while resin bonds offer flexibility and are good for finer finishes. 6. **RPM and Tool Compatibility**: Ensure the mounted point is compatible with the RPM of your tool. Exceeding the recommended speed can lead to tool failure or safety hazards. 7. **Application**: Match the mounted point to the specific application, such as deburring, polishing, or grinding. Each task may require a different type of mounted point. 8. **Durability and Cost**: Consider the durability and cost-effectiveness of the mounted point. High-quality points may have a higher upfront cost but offer longer life and better performance. By evaluating these factors, you can select the most appropriate mounted point for your specific task, ensuring efficiency and quality in your work.

To attach mounted points to rotary tools, follow these steps: 1. **Select the Right Collet or Chuck**: Ensure the rotary tool is equipped with a collet or chuck that matches the shank size of the mounted point. Most rotary tools come with interchangeable collets or an adjustable chuck to accommodate different shank sizes. 2. **Power Off and Unplug**: For safety, ensure the rotary tool is powered off and unplugged before making any adjustments. 3. **Loosen the Collet Nut or Chuck**: Use the provided wrench or tool to loosen the collet nut or chuck. This will allow you to insert the shank of the mounted point. 4. **Insert the Mounted Point**: Slide the shank of the mounted point into the collet or chuck. Ensure it is inserted deeply enough to be secure but not so deep that it affects the tool's balance or performance. 5. **Tighten the Collet Nut or Chuck**: Once the mounted point is in place, use the wrench to tighten the collet nut or chuck securely. Ensure it is tight enough to hold the mounted point firmly during operation. 6. **Check Alignment and Security**: Before powering on the tool, check that the mounted point is aligned properly and securely fastened. Spin the tool manually to ensure there is no wobbling. 7. **Test Run**: Plug in and power on the rotary tool at a low speed to test the mounted point's stability. Gradually increase the speed to the desired level, ensuring the mounted point remains secure and balanced. 8. **Adjust as Necessary**: If there is any wobbling or instability, power off the tool, readjust the mounted point, and retighten the collet or chuck. Following these steps ensures the mounted point is securely attached, allowing for safe and effective operation of the rotary tool.

Mounted points come in various shapes, each designed for specific applications and surface finishes. The most common shapes include: 1. **Cylindrical**: Used for surface grinding and finishing flat surfaces. They are ideal for deburring and smoothing. 2. **Conical**: These are tapered and used for precision grinding in hard-to-reach areas. They are excellent for deburring and finishing in tight spaces. 3. **Ball**: Spherical in shape, these are used for contouring and finishing curved surfaces. They are also effective for deburring and polishing. 4. **Tapered**: These have a gradual taper and are used for precision work in confined spaces. They are suitable for grinding and finishing in narrow areas. 5. **Flame**: Shaped like a flame, these are used for detailed work and finishing in intricate areas.
