Why Cobalt Drill Bits For Hardened Steel Is Necessary?
Choosing the right drill bit for hardened steel is essential to ensure an effective and successful drilling job. Hardened steel is a tough material that requires specialized drill bits, specifically designed to withstand its strength and hardness. This type of metal may cause regular, high-speed steel (HSS) bits to wear out quickly, so it’s recommended that cobalt drill bits are used instead.
Cobalt-based alloy HSS drills tend to be more durable than standard HSS options due to their ability stay sharper longer when carving through metal at higher speeds—an important factor when dealing with anything harder than normal carbon steels like 316 stainless or Chromoly tubular alloys. This increased durability also lends longevity when tackling hardened materials such as chrome molybdenum or nickel plated bar stock from automotive or aerospace factories.

Buying Guide for Best Cobalt Drill Bits For Hardened Steel
Types of Cobalt Drill Bits
Cobalt drill bits are a type of high-speed steel drill bit with an increased amount of cobalt in the alloy. This makes them harder and more wear resistant than typical HSS drill bits, making them ideal for drilling through hardened steel. They come in a variety of sizes and styles, so it is important to know which type is best for your project.
• Regular Cobalt Drill Bits – Regular cobalt drill bits are ideal for drilling through softer metals such as aluminum, brass, and copper. They are generally less expensive than other types of cobalt drill bits.
• Titanium-Coated Cobalt Drill Bits – Titanium-coated cobalt drill bits are designed to provide increased wear resistance when drilling through hard metals such as stainless steel and titanium alloys. They also offer superior corrosion resistance compared to regular cobalt drill bits.
• Parabolic Flute Cobalt Drill Bits – Parabolic flute cobalt drill bits feature a unique fluted design that helps to clear chips away from the hole being drilled faster than traditional straight flute designs. This makes them ideal for drilling through hard materials such as hardened steel.
Factors To Consider When Buying Cobalt Drill Bits
When buying cobalt drill bits for hardened steel, there are several factors to consider:
• Material – The material you’re drilling into will determine which type of cobalt bit is best suited for the job. If you’re drilling into softer metals such as aluminum or brass, a regular HSS bit may be sufficient, while harder materials like stainless steel or titanium require a titanium-coated or parabolic flute bit.
• Size – The size of the hole you need to drill will determine which size bit you need to purchase. Make sure you buy a bit that is large enough to accommodate the hole size needed but not so large that it risks damaging the material being drilled into.
• Quality – Pay close attention to the quality of the cobalt drill bits you purchase as this can have a major impact on their performance and longevity when drilling into hard materials like hardened steel. Look for products from reputable brands that offer good quality control and warranty coverage if anything goes wrong with your purchase.
• Price – Price is always an important factor when shopping for tools, but it’s especially important when buying something like high-quality cobalt drill bits that need to perform well in order to get the job done right. Look for products that offer good value by balancing price with quality in order to get the most bang for your buck without sacrificing performance or longevity.
Tips For Using Cobalt Drill Bits For Hardened Steel
• Make sure your drill is set up properly and securely before beginning any drilling operation with a cobalt bit, as this will help ensure accuracy and reduce potential damage due to wobbling during use.
• Always use cutting oil or lubricant while using any type of high-speed steel or carbide bit on metal surfaces as this will help reduce friction and keep chips from clogging up the flutes while drilling into hard materials like hardened steel.
• Make sure you choose an appropriate speed setting based on the material being drilled into in order to reduce heat buildup during use which can cause premature wear on both the tool and material being drilled into if not done correctly.
• If possible, try using a lower speed setting combined with multiple passes at increasing depths instead of one pass at full depth in order to reduce heat buildup which can cause premature wear on both the tool and material being drilled into if not done correctly
