Common Mistakes When Using SDS Hammer Drill Bits and How to Avoid Them


SDS Hammer Drill Bits are widely used in drilling concrete, masonry and other hard materials due to their efficient striking power and excellent drilling performance. However, many users tend to make common mistakes when using SDS hammer drill bits due to improper operation or lack of experience, resulting in damage to the drill, inaccurate drilling and even safety issues. Below are five common mistakes made when using SDS hammer drill bits and how to avoid them.


1. Wrong choice of drill bit

A common mistake is choosing the wrong type and size of drill bit. Different materials and drilling needs require different types of drill bits. For example, a drill bit used for concrete is different from one used for masonry or tile. Using the wrong drill bit may result in inefficient drilling or even damage to the drill bit.

--Be sure to select the appropriate SDS hammer drill bit for the type of material before starting work. Read the product manual carefully or consult a professional to ensure that the right tool is selected.


2. Incorrect operating angle

When using SDS hammer drill bits, it is important to maintain the correct operating angle. Drilling at the wrong angle not only affects the accuracy of the drill, but can also cause the drill bit to become stuck in the material, or even cause damage to the drill bit or the machine.

-Make sure the drill is perpendicular to the surface of the material before you start drilling and maintain this angle during the drilling process. Use a guide or ruler if necessary to help maintain the correct angle.


3. Neglect of lubrication and cooling


When SDS hammer drill bits are used for extended periods of time, the bit generates a lot of heat due to friction. Without proper lubrication and cooling, the drill bit may become overheated and wear may increase or even break.

-Use a suitable coolant or lubricant and take regular breaks during continuous operation to allow the drill bit to cool down. Also consider intermittent drilling to minimize heat buildup in the drill bit.


4. Neglect of drill bit maintenance


Many users of SDS hammer drill bits neglect routine maintenance of the drill bits. After long-term use, the cutting edge of the drill bit will wear out, affecting its drilling efficiency and service life.

-Check the wear of the drill bits regularly and sharpen or replace them if necessary. In addition, clean the surface of the drill bit after use to avoid the accumulation of dust and debris, which can affect the performance of the drill bit.


5. Excessive force


When using SDS Hammer Drill bits, many users habitually apply too much pressure in the belief that this will increase drilling speed. In fact, over-application of force does not improve efficiency, but can damage the drill bit and even cause the machine to malfunction.

-Allow the drill and machine to function as they should by applying just the right amount of pressure and maintaining a steady hand. Let the natural striking force of the tool do most of the work; applying excessive force is counterproductive.


SDS hammer drill bits are a great tool for efficient drilling, but only if they are used and maintained correctly. Avoiding the common mistakes mentioned above will not only prolong the life of the drill bit, but also improve efficiency and ensure safe construction. We hope these tips will help you achieve better results in your daily use.
