This High-Speed Steel (HSS) drill bit set, with a Titanium coating, is a solid recommendation for drilling into hardened steel and is perfect for sheet metal and other thin materials. COMOWARE Step Drill Bit Set – Best Step Drill Bit for Metal While this set isn’t specifically designed for hardened steel, the durability of the Titanium Nitride coating and the advantageous 135-degree cutting angle makes it a strong choice for working with regular metal and hardened steel.
Their 30-day money-back guarantee provides extra assurance of the quality of their products. Importantly, these bits have a cutting angle of 135 degrees, an ideal design for hardened steel, as it reduces drilling force and prevents bit ‘wandering’.ĭEWALT is a reputable industry brand known for producing durable and reliable tools. The set features a straight shank design, compatible with most drills, and the bits come in various sizes, ranging from 1/16 inch up to 1/2 inch, ensuring versatility for different drilling needs. The bits are coated with Titanium Nitride, a finish that significantly enhances hardness and longevity, allowing for smooth, efficient cutting even through tough materials. The DEWALT DW1354 14-Piece Drill Bit Set is an optimal choice for drilling metal and hardened steel. DEWALT DW1354 – Best 14PC SET for Hardened Steel
We have included various drill bits that we are confident will be a drill through even the hardest metal: 1. Some bits are designed to handle heat or work with certain coolants.Īlways use the correct drill speed and pressure to prevent overheating or breakage. Coolant: Use a coolant or cutting fluid to reduce heat and prolong bit life.Manufacturer: Research and read reviews to find reliable brands.Shank Design: A straight shank works for hand drills, while a tapered shank may be better for drill presses.You might need to test different sizes initially. Size: Ensure the drill bit size matches your needs.Bit Design: A 135-degree split point design reduces the force needed to drill and prevents ‘wandering’ at the start.Coating: Coatings like Titanium Nitride (TiN), Titanium Carbon Nitride (TiCN), Titanium Aluminum Nitride (TiAlN), or diamond enhances hardness, reduce friction, and increase bit lifespan.Diamond is typically overkill for most steels. Carbide is even harder but can chip easily. Cobalt is more durable and heat-resistant. Material: Bits for hardened steel are usually made from high-speed steel (HSS), cobalt, carbide, or diamond.Additionally, slower drill speeds, constant lubrication to manage heat, and a 135-degree split point bit for better penetration and to prevent ‘wandering’ are recommended.Ĭhoosing the right drill bits for hardened steel involves several considerations: However, due to its increased hardness and strength, hardened steel demands more robust materials like cobalt, carbide or titanium nitride drill bits.
High-speed steel (HSS) bits work well for most metals, proper speed prevents overheating, and lubrication extends the bits lifespan. What should you consider when looking at getting drill bits for hardened steel:įactors such as drill bit material, speed, and lubrication are important when drilling metal. Thank you to the 911 community for their feedback and support in finalizing the list: 3 Drill Bits for Hardened Steel That We Recommend in 2023: We have analyzed the latest customer sentiment data and broken them down by specific metal-cutting needs.
Luckily, we’ve done enough research for the best drill bits for this type of metal. So, what drill bits should you use for hardened steel?įinding the right drill bits for hardened steel can be tricky because drilling through hard metal is harder than drilling through wood, glass, or plastic, and you’ll need a tougher drill bit. That being said, the effectiveness of a drill isn’t measured by the power of the drill itself but rather by the quality of the drill bits. Trying to drill holes with the wrong bits can make anyone insane as the drill bit spins in one place. If your drill bits aren’t up to the task, even the most powerful drill won’t help you. Your drill bits need to be sturdy enough to cut holes in various materials, including steel, while following the same quality and dimensions requirements to be practical for your business. Are you looking for drill bits to cut holes in hardened steel?ĭrills are among the most essential tools that can be found in a DIYer’s toolbox.
