Mounted points are tiny grinding instruments that are mounted on a metal shaft. They carve, smoothen, and polish narrow or tight areas.

It might sound simple to do precision grinding, but every person working with metal is aware that it requires the appropriate method to achieve a clean, smooth, and accurate finish. The mounted points are useful in any shop, whether it is a small shop or a large machine shop, to shape, smooth, and finish small areas. Most of the professionals purchase their mounted points from an abrasive tools supplier Dubai to do their daily tasks.

Additionally, they come in a variety of shapes, sizes, and materials as mounted points. With the right knowledge on how to use them, your grinding can turn out to be different. This guide will help you to know how to use mounted points to achieve the best finish without damaging the tool and the workpiece.

What are mounted points?

Mounted points are miniature grinding instruments produced of bonded abrasive grains. They are attached to a steel shaft, which is inserted into a rotary tool, a grinder, or a drill. They are small but handy when you need precision where a regular grinding wheel is unable to reach.

They are commonly used for:

• Deburring small edges
• Cleaning welds
• Finishing cavities or slots
• Smoothing tight corners
• Polishing dies and molds

However, there are also mounted points of various grades depending on the hardness of the workpiece.

Why are mounted points used in precision grinding?

Mounted points are ideal in use where big wheels just cannot go. They allow you to work slowly and with care and are thus ideal in delicate work.

This is why they are trusted by professionals:

• They provide much control in limited areas.
• They assist in the attainment of smooth finishes.
• They do not leave material waste in the surroundings.
• They minimize chances of over grinding.
• They are good at detail or final finishing.

Furthermore, abrasive tools dealers in Dubai also sell these tools to many technicians since they have a variety of tools depending on the materials.

How to choose the right mounted point?

It is important to select the appropriate mounted point and not just to use it. Most users choose the incorrect point and spoil the workpiece.

Here’s what you should look at:

1. Shape

Various occupations require various forms:

• Cylindrical: Use on flat surfaces.  
• Cone: Good for small corners  
• Ball: Good for curves  
• Oval: Suited to general finishing.

2. Material Type

Common types include:

• Aluminum oxide:  General purpose.  
• Silicon carbide: One of the harder metals or stones.  
• Ceramic: Cutting high performance.

3. Grit Size

• Fine grit: smooth finish  
• Coarse grit: fast material removal.

4. Shank Size

Select the size of the shank to match your rotary tool or grinder.

Moreover, depending on the project, other workshops also use cutting and milling tools Dubai in bigger projects.

Steps to use mounted points for precision grinding

The proper use of mounted points contributes to the extended life of the tools and better finish and eliminates errors. These fundamental procedures are to be used in nearly all precision grinding jobs.

Step 1: Choose the appropriate mounted point 

Consider the form, roughness, and substance. Ensure that the point aligns with the metal or surface that you are working on.

Step 2: Secure the Workpiece  

You should be tightening your workpiece first. This lessens vibration and puts you in control.

Step 3: Install the mounted point in a proper manner  

Place the shank completely into the collet of the tool. Do not leave it half‑in. When rotating fast, a loose shank may bend or break.

Step 4: Adjust the speed  

Begin slowly and then go up. Do not start at a high speed, as it may lead to burning or irregular grinding.

Step 5: Begin to grind with light pressure  

Apply only light pressure. Allow the tool to do the majority. Excessive pressure causes the tool to get hot and lose precision.

Step 6: Keep the tool moving  

Do not leave the mounted point in one place for too long. Move it in gentle movements to prevent marks or dents.

Step 7: Monitor heat  

In case the workpiece becomes excessively hot, wait a few seconds. Heat may destroy both the mounted point and your material.

Step 8: Inspect the Finish  

Inspect the surface regularly. This ensures that you do not end up taking away too much material accidentally.

Step 9: Change the mounted point when necessary 

An overloaded point may scratch the surface and reduce accuracy. Change it in time to achieve the best finishing.

However, others depend on reputable suppliers of tools, such as saif precision tools, to get reliable grinding and finishing tools.

Safety tips you should never ignore

Even though mounted points are small, they should be treated with care. Always remember these safety precautions:

• Wear a mask, goggles, and gloves.  
• Do not overrun the suggested RPM.  
• Be sure that the shank is tightened.  
• Do not keep your hands in rotating parts.  
• Cracked or damaged points should not be used.  
• Operate in a clean and dry place.  
• Never ignore the instructions of the tool.  

Therefore, it is recommended to check the mounted point prior to every use to avoid sudden breakage.

Conclusion

Mounted points can be small; however, they drive precision grinding. When properly utilized, they can assist you in getting into tight spots, carving your piece of work into shape, and producing a smooth finish. The kind of type, correct speed, and gentle pressure can serve a great purpose in improving your results. 

Furthermore, no matter whether you are an amateur or a professional technician, these steps will help you work more confidently and safely and in a shorter time. A large number of workshops have a reliable supplier of abrasive tools in Dubai to maintain quality and consistency in each grinding project.

Therefore, using the methods of this guide, you will be able to achieve clean and professional-quality finishes and ensure the durability of your tools with ease.
