Hardened steel is much harder than the materials that regular drill bits are designed to drill through. No, you cannot drill through-hardened steel with a regular drill bit. Take breaks often to allow the drill bit to cool down.Ĭan I drill through-hardened steel with a regular drill bit?.If you drill too quickly, the bit will overheat and break. Drill slowly and apply steady pressure to the drill bit.Water is the best lubricant for this application, but oil can also be used. Use a lubricant to help cool the bit and prevent it from overheating.These bits are made of a harder material than carbide-tipped bits. Diamond-tipped drill bits are another option for drilling through hardened steel.They are designed to withstand the high temperatures and pressures associated with drilling through hard materials. Carbide-tipped drill bits are the most common type of bit used for this application.There are two main types of drill bits for hardened steel: carbide-tipped drill bits and diamond-tipped drill bits: What are the different types of drill bits for hardened steel? With these tips in mind, you should be able to drill through hardened steel successfully. Apply steady pressure to the drill bit and drill slowly to avoid breaking it.Use a lubricant to help cool the drill bit and prevent it from overheating.Always use a carbide-tipped drill bit as they are designed for this application.There are a few tips to keep in mind when drilling through hardened steel to ensure success as follows: ![]() Tips for drilling hardened steel successfully Once the pilot hole is created, switch to a larger drill bit and slowly increase the size of the hole.Īs with a power drill, it is important to use a lubricant to help cool the drill bit and prevent it from overheating. ![]() Start by creating a small pilot hole with a carbide-tipped drill bit. This will require more effort on your part, but it is possible. If you don’t have access to a power drill, you can drill hardened steel with a hand drill. Drilling hardened steel with a hand drill Start with a small pilot hole before drilling the final hole to the desired size. Water is the best lubricant for this application, but oil can also be used.įinally, it is important to drill slowly and apply steady pressure to the drill bit to avoid breaking it. When drilling through hardened steel, it is important to use a lubricant to help cool the drill bit and prevent it from overheating. This type of bit is designed to withstand the high temperatures and pressures associated with drilling through hard materials. The best way to drill hardened steel is with a carbide-tipped drill bit. It is often used in applications where strength and durability are required, such as in construction or mining. Hardened steel is a type of steel that has been heat treated to resist wear, breakage, and deformation.
