Also, look for ones that are carbide tipped. Although some drill bits are marketed as multi-function, it’s best to get the right bit for the job.

Choose high-quality masonry drill bits.

If you are drilling into a concrete wall that is 8 inches thick you need a bit at least 9 inches long.

Drill bits to the length you need – the length should be at least an inch longer than the material you need to drill through.

Make sure you get one powerful enough for your needs, that it does not only have one speed and that it is safe with a stop function. If you do not want to invest in one to add to your tool collection rent one.

Hammer drills (or rotary hammers as they are also called) – the good ones can go down into two inches of concrete in only a minute which is a lot faster than a rotary drill.

You are probably going to have to invest in some more concrete drilling tools or rent the right ones out to have any success with drilling into concrete. Here is a guide with some useful tips on drilling concrete.

But that strength and durability can have a double-edged sword when you are trying to change things up. Concrete is a great material, it is versatile, strong and durable.

However, whether you love DIY or are new to it, it does not mean you know properly how to drill into concrete. Low-quality bits tend to be less precise and efficient and would often break sooner than you expect.If you are carrying out a construction project yourself you are likely someone who enjoys the process and has some knowledge and experience with various DIY jobs. While most drilling bits can make a hole in hard materials, it doesn’t mean the proficiency is the same. Not sure if you need to replace your bits? Here are some signs that you may have to do it sooner than you think. Signs You Need to Replace Your Drill Bits Configuring the settings the wrong way – using the wrong settings like bit load and speed can break your bits.Using too much or too little pressure – applying too much pressure causes the bit to break while less pressure can make it dull.Using the wrong drilling bits – using the wrong bits can make them break faster or dull sooner.Mistakes You Make That Cause Drill Bits to Break You can also use coolants and lubricants to fasten the cooling time of the bits. Make sure to rest your drill from time to time to let it cool down. The extreme heat can soften up bits and make them break easily. Extreme Heatĭrilling for too long can cause extreme heat because of the friction the drill creates. Make sure to check the drill point geometry and correct it or replace the bit altogether. This can be related to the chisel point, lip height gap, or chipping. Sometimes, the geometry of your drill bits is wrong. Just use the right length bit to avoid breaking. This would also lead to the drill bit breaking because of too much length. When the bit length is too long, the drilling can be problematic and you might see reduced accuracy. You can enlarge the chip pocket volume or the thickness or taper to accommodate more load. Increased load causes breakage, especially in the middle of the bit. If you want your low-quality bit to last a little longer, you can change the web thickness and web taper. It happens when deflection causes the bit to break at the end of the flute. This reason is evident in low-quality bits. High torque will also cause the drill to break. A drill generally breaks at the end of the flute because of radial force. This happens when you don’t use them properly. Your bits can break way before 150 holes. Some types of bits can last for around 10,000 holes with a minimum of 1,500 holes. Other types of drilling bits can last even longer. It can be stainless steel, aluminum, structural steel, or low-carbon steel. High-speed steel drilling bits can last from 150 to 450 holes depending on where they’re drilled at.
